Abstract
Species of the genus Lathrobium Gravenhorst (Coleoptera: Staphylinidae: Paederinae) from North America north of Mexico are reviewed and 41 species are recognized. Morphology and mitochondrial COI sequence data were used to guide species designations in three flightless lineages endemic to the southern Appalachian Mountains, a biologically diverse region known for cryptic diversity. Using a combination of phylogeny, algorithm-based species delimitation analyses, and genitalic morphology, five new cryptic species are described and possible biogeographic scenarios for their speciation hypothesized: L.balsamense Haberski & Caterino, sp. nov., L.camplyacra Haberski & Caterino, sp. nov., L.islae Haberski & Caterino, sp. nov., L.lividum Haberski & Caterino, sp. nov., L.smokiense Haberski & Caterino, sp. nov. Five additional species are described: L.absconditum Haberski & Caterino, sp. nov., L.hardeni Haberski & Caterino, sp. nov., L.lapidum Haberski & Caterino, sp. nov., L.solum Haberski & Caterino, sp. nov., and L.thompsonorum Haberski & Caterino, sp. nov. Two species are transferred from Lathrobium to Pseudolathra Casey: Pseudolathraparcum (LeConte, 1880), comb. nov. and Pseudolathratexana (Casey, 1905), comb. nov. Twenty-six names are reduced to synonymy. Lectotypes are designated for 47 species. Larvae are described where known, and characters of possible diagnostic value are summarized. Species diagnoses, distributions, illustrations of male and female genitalia, and a key to Lathrobium species known from the Nearctic region (including several introduced species) are provided.

Abstract
The Pseudoscorpiones fauna of North America is diverse, but in regions like the southern Appalachian Mountains, they are still poorly documented with respect to their species diversity, distributions and ecology. Several families have been reported from these mountains and neighbouring areas. Here we analyse barcoding data of 136 specimens collected in leaf litter, most of them from high-elevation coniferous forest. We used ASAP as a species delimitation method to obtain an estimation of the number of species present in the region. For this and based on interspecific genetic distance values previously reported in Pseudoscorpions, we considered three different genetic Kimura two-parameter distance thresholds (3%/5%/8%), to produce more or less conservative estimates. These distance thresholds resulted in 64/47/27 distinct potential species representing the families Chthoniidae (33/22/12 species) and Neobisiidae (31/25/15) and at least six different genera within them. The diversity pattern seems to be affected by the Asheville Depression, a major biogeographic barrier in this area, with a higher diversity to the west of this geographic feature, particularly within the family Neobisiidae. The absence of representatives from other families amongst our studied samples may be explained by differences in their ecological requirements and occupation of different microhabitats.

Abstract
The close association between bacteria and insect hosts has played an indispensable role in insect diversity and ecology. Thus, continued characterization of such insect-associated-microbial communities is imperative, especially those of saprophagous scarab beetles. The bacterial community of the digestive tract of adults and larvae of the cetoniine scarab species Cotinis nitida is characterized according to life stage, gut structure, and sex via high-throughput 16S rRNA gene amplicon sequencing. Through permutational ANOVAs of the resulting sequences, bacterial communities of the digestive system are shown to differ significantly between adults and larvae in taxon richness, evenness and relatedness. Significant bacterial community-level differences are also observed between the midgut and hindgut in adult beetles, while no significant host-sex differences are observed. The partitioning between bacterial communities in the larval digestive system is shown through significant differences in two distinct hindgut regions, the ileum and the expanded paunch, but not between the midgut and ileum portion of the hindgut region. These data further corroborate the hypothesis of strong community partitioning in the gut of members of the Scarabaeoidea, suggest hypotheses of physiological-digestive association, and also demonstrate the presence of a seemingly unusual non-scarab-associated taxon. These findings contribute to a general portrait of scarabaeoid digestive tract bacterial communities while illuminating the microbiome of a common new world cetoniine of the Gymnetini-a tribe largely neglected in scarab and beetle microbiome and symbiosis literature.

Abstract
We describe a second species of Nearctomeris Wesener, 2012, a genus of pill millipede endemic to the southern Appalachians, based on morphological and molecular evidence. The fauna of Glomerida in America is characterized by its low diversity, and Nearctomerissmokysp. nov. is only the fifth species of the order known from the eastern United States. Our phylogenetic analyses based on COI sequences recover a tentatively monophyletic lineage including both eastern American genera Onomeris Cook, 1896 and Nearctomeris, with a common ancestor in the Late Cretaceous to Mid Eocene and extant diversity within genera dating back to the Miocene. Our results suggest that the observed low diversity of the group in the eastern US is likely caused by extinction events, but it is also possible that new species are yet to be found. We provide new records for Nearctomerisinexpectata Wesener, 2012, Onomerisunderwoodi Cook, 1896 and O.australora Hoffman, 1950; the latter is here reported for the first time from South Carolina. We also present DNA barcoding data for all species of Glomerida present in the US that are not yet publicly available.

Abstract
The beetle fauna of the California Channel Islands is here enumerated for the first time in over 120 years. We provide an annotated checklist documenting species-by-island diversity from an exhaustive literature review and analysis of a compiled dataset of 26,609 digitized specimen records to which were added over 3,000 individual specimen determinations. We report 825 unique species from 514 genera and 71 families (including 17 new family records) comprising 1,829 species-by-island records. Species totals for each island are as follows: Anacapa (74); San Clemente (197); San Miguel (138); San Nicolas (146); Santa Barbara (64); Santa Catalina (370); Santa Cruz (503); and Santa Rosa (337). This represents the largest list of species published to date for any taxonomic group of animals on the Channel Islands; despite this, we consider the checklist to be preliminary. We present evidence that both inventory and taxonomic efforts on Channel Islands beetles are far from complete. Rarefaction estimates indicate there are at least several hundred more species of beetles yet to be recorded from the islands. Despite the incomplete nature of existing records, we found that species diversity is highly correlated with island area. We report 56 species which are putatively geographically restricted (endemic) to the Channel Islands, with two additional species of questionable endemic status. We also report 52 species from the islands which do not natively occur in the southern California region.

Abstract
Thirteen new species of Euconnus Thomson (Staphylinidae: Scydmaeninae: Glandulariini) are described from the southern Appalachian Mts, USA: Euconnusmegalops sp. nov., E.vexillus sp. nov., E.cumberlandus sp. nov., E.vetustus sp. nov., E.adversus sp. nov., E.astrus sp. nov., E.cultellus sp. nov., E.falcatus sp. nov., E.cataloochee sp. nov., E.kilmeri sp. nov., E.draco sp. nov., E.tusquitee sp. nov., and E.attritus sp. nov. These share a number of morphological characters with the Old World subgenus Cladoconnus Reitter, representing a diversification of species distinct from anything previously known from the western hemisphere. Most of the species occur at higher elevations, some at the tops of the region's highest mountains, and a few are single-peak endemics. No females of these species are winged, and in several species neither sex is winged. A preliminary phylogeny suggests the wingless species represent a clade within a clade of wing-dimorphic species.

Abstract
For the first time, an extant histerid genus Anapleus Horn, 1873 is described from a specimen found in mid-Cretaceous Kachin amber. Anapleus kachinensis sp. nov. Although the genus Anapleus has not been precisely defined by synapomorphies, the new species shares numerous features with extant species while differing in comparatively few external characteristics. Anapleus kachinensis represents the first record of an extant histerid genus from Cretaceous deposits and provides further evidence of the ancient origin of the genus.

Abstract
In order to place a newly discovered species Antigracilus costatus gen. sp. n. from the Lower Cretaceous Yixian Formation (China) and to assess previously unplaced fossil taxa, we investigated the relationships of extant and extinct lineages of Histeridae based on three data sets: (i) 69 morphological characters belonging to 48 taxa (representing all 11 subfamilies and 15 of 17 tribes of modern Histeridae); (ii) partitioned alignment of 6030 bp from downloaded nucleotide sequences (28S, CAD, COI, 18S) of 50 taxa (representing 10 subfamilies and 15 of 17 tribes of modern Histeridae); and (iii) a combined morphological and molecular dataset for 75 taxa. Phylogenetic analyses of the morphology and combined matrices recovered the new Lower Cretaceous taxon as a sister group to remaining Histeridae and it is placed in †Antigracilinae subfam. n. †Antigracilinae constitutes the earliest record of Histeridae from the Lower Cretaceous Yixian Formation (∼125 Myr), backdating the minimum age of the family by 25 Myr from the earliest Cenomanian (~99 Myr) to the Barremian of the Cretaceous Period. Our molecular phylogeny supports Histeridae to be divided into seven different clades, with currently recognised subfamilies Abraeinae (sensu lato), Saprininae, Chlamydopsinae, and Histerinae (sensu lato) recovered as monophyletic, while Dendrophilinae, Onthophilinae, and Tribalinae are polyphyletic taxa. The Burmese amber species †Pantostictus burmanicus Poinar & Brown is placed as a sister group to the tribe Plegaderini (Abraeinae) and was assigned as a new tribe Pantostictini trib. n. Both molecular and combined phylogenies recovered the subfamilies Trypanaeinae and Trypeticinae deeply within the subfamily Abraeinae (sensu lato), and they are downgraded into Trypanaeini stat. n. and Trypeticini stat. n.

Forty-nine new species of Neotropical Exosternini are described in this work, representing the newly recognized Phelister blairi species group, within the large, heterogeneous taxon Phelister. Eight previously described species are also assigned to this group. Relationships within are indicated with several informal subgroups: P. blairi subgroup: (P. blairi Hinton, 1935, P. erwini sp. nov., P. fimbriatus sp. nov., P. stellans sp. nov., P. sparsus sp. nov., P. pretiosus sp. nov., P. trigonisternus Marseul, 1889, P. globosus sp. nov., P. serratus sp. nov., P. geminus sp. nov., P. parana sp. nov., P. asperatus sp. nov., P. uniformis sp. nov., P. miscellus sp. nov., P. inbio sp. nov., P. sculpturatus Schmidt, 1893, P. tunki sp. nov., P. praedatoris Reichensperger, 1939, P. ifficus sp. nov., P. genieri sp. nov., P. marginatus sp. nov., P. vazdemelloi sp. nov., P. dilatatus sp. nov., P. spectabilis sp. nov., P. pervagatus sp. nov.); P. amazoniae subgroup: (P. morbidus sp. nov., P. annulatus sp. nov., P. sphaericus sp. nov., P. geijskesi Kanaar, 1997, P. fraternus sp. nov., P. conjunctus sp. nov., P. chabooae sp. nov., P. striatinotum Wenzel & Dybas, 1941, P. notandus Schmidt, 1893, P. amazoniae (Lewis, 1898) comb. nov., P. arcuatus sp. nov.); P. gregarius subgroup: (P. gregarius sp. nov., P. praecisus sp. nov., P. rudis sp. nov., P. incongruens sp. nov., P. congruens sp. nov., P. praesignis sp. nov.); P. umens subgroup: (P. umens sp. nov., P. almeidae sp. nov., P. chicomendesi sp. nov., P. microdens sp. nov., P. matatlantica sp. nov.); P. curvipes subgroup: (P. curvipes sp. nov., P. vilavelha sp. nov.); P. rio subgroup: (P. rio sp. nov., P. semotus sp. nov., P. uncinatus sp. nov., P. inscriptus sp. nov.); incertae sedis - unplaced to subgroup: (P. incertus sp. nov., P. okeefei sp. nov., P. blairoides sp. nov., P. pirana sp. nov.). Lectotypes are designated for the following species: P. trigonisternus Marseul, P. sculpturatus Schmidt, P. praedatoris Reichensperger, P. notandus Schmidt, and Discoscelis amazoniae Lewis. Preliminary phylogenetic analyses of the broader Neotropical Exosternini do not support the monophyly of the P. blairi group, nor of all of these subgroups, but the majority do fall within one large clade (which is potentially paraphyletic with respect to some other Neotropical exosternine genera). More work on the phylogeny and taxonomy of this diverse fauna is needed.

Abstract
Background Páramo is a tropical alpine ecosystem present in the northern Andes. Its patchy distribution imposes limits and barriers to specialist inhabitants. We aim to assess the effects of this habitat distribution on divergence across two independently flightless ground beetle lineages, in the genera Dyscolus and Dercylus. Methods One nuclear and one mitochondrial gene from 110 individuals from 10 sites across the two lineages were sequenced and analyzed using a combination of phylogenetics, population genetic analyses, and niche modeling methods. Results The two lineages show different degrees of population subdivision. Low levels of gene flow were found in Dyscolus alpinus, where one dominant haplotype is found in four out of the six populations analyzed for both molecular markers. However, complete population isolation was revealed in species of the genus Dercylus, where high levels of differentiation exist at species and population level for both genes. Maximum entropy models of species in the Dercylus lineage show overlapping distributions. Still, species distributions appear to be restricted to small areas across the Andes. Conclusion Even though both beetle lineages are flightless, the dispersal ability of each beetle lineage appears to influence the genetic diversity across fragmented páramo populations, where Dyscolus alpinus appears to be a better disperser than species in the genus Dercylus.

Abstract
The Phelisterhaemorrhous species group is established here, revising the seventeen included species, four of which are described as new. This group is named for and contains the type species of Phelister, so represents a core around which a modern concept of the dumping-ground genus Phelister may be developed. The group includes several common and well-known species in the Americas, including some of the only Phelister to exhibit distinctive coloration.

Abstract
Background Southern Appalachian forests are dominated by second-growth vegetation following decades of intensive forestry and agricultural use, although some old-growth patches remain. While it’s been shown that second-growth areas may exhibit comparable species richness to old-growth in the area, the extent to which populations of arthropods in second-growth areas have persisted vs. recolonized from other areas remains unexamined. The implications for conservation of both classes of forest are significant. Here we analyze population diversity and relatedness across five old-growth and five second-growth populations of flightless, leaf litter-inhabiting beetles in the genus Eurhoptus (Coleoptera: Curculionidae: Cryptorhynchinae). Our main goal is asking whether second-growth areas show diminished diversity and/or signals of recolonization from old-growth sources. Results Population genetic and phylogenetic analyses do not reveal any consistent differences in diversity between the old-growth and second-growth populations examined. Some second-growth populations retain substantial genetic diversity, while some old-growth populations appear relatively depauperate. There is no phylogenetic indication that second-growth populations have recolonized from old-growth source populations. Conclusions Most populations contain substantial and unique genetic diversity indicating long-term persistence in the majority of sites. The results support substantial resilience in second-growth populations, though the geographic scale of sampling may have hindered detection of recolonization patterns. Broad scale phylogeographic patterns reveal a deep break across the French Broad River basin, as has been reported in several other taxa of limited dispersal abilities. In Eurhoptus this break dates to ~ 2–6 Ma ago, on the older end of the range of previously estimated dates.

Abstract
We describe a new genus and species of Histeridae from Upper Cretaceous Burmese amber, Amplectister tenax Caterino & Maddison, gen. & sp. n. This species represents the third known Cretaceous histerid, which, like the others, is highly distinct and cannot easily be placed to subfamily. It exhibits prosternal characters in common with Saprininae, but other characters appear inconsistent with this possibility. The abdominal venter is strongly concave, and the hind legs are enlarged and modified for grasping. We hypothesize that this represents the earliest example in Histeridae of modifications for phoresy on social insects.

Abstract
We revise the genus Prespelea Park, redefining and redescribing the two previously known species, P.copelandi Park and P.quirsfeldi Park, and adding ten new species: P.parki Caterino & Vásquez-Vélez, sp. n., P.minima Caterino & Vásquez-Vélez, sp. n., P.morsei Caterino & Vásquez-Vélez, sp. n., P.divergens Caterino & Vásquez-Vélez, sp. n., P.carltoni Caterino & Vásquez-Vélez, sp. n., P.myersae Caterino & Vásquez-Vélez, sp. n., P.georgiensis Caterino & Vásquez-Vélez, sp. n., P.enigma Caterino & Vásquez-Vélez, sp. n., P.wagneri Caterino & Vásquez-Vélez, sp. n., and P.basalis Caterino & Vásquez-Vélez, sp. n.. The genus is still only known from a relatively small area in the southern Appalachian Mountains, but the diversity is much greater than previously suspected. The new species exhibit considerable diversity in male secondary sexual characters. A preliminary phylogenetic analysis cannot conclusively resolve the polarity of eye and wing reduction across Speleobamini, but the monophyly of Park’s subgenus Fusjugama, if expanded to include all species with full-eyed and winged males, is not supported, and we therefore synonymize it with Prespeleas. str.

Abstract
The Lepidoptera of North America Network, or LepNet, is a digitization effort recently launched to mobilize biodiversity data from 3 million specimens of butterflies and moths in United States natural history collections (http://www.lep-net.org/). LepNet was initially conceived as a North American effort but the project seeks collaborations with museums and other organizations worldwide. The overall goal is to transform Lepidoptera specimen data into readily available digital formats to foster global research in taxonomy, ecology and evolutionary biology.

Abstract
External and internal morphological characters of extant and fossil organisms are crucial to establishing their systematic position, ecological role and evolutionary trends. The lack of internal characters and soft-tissue preservation in many arthropod fossils, however, impedes comprehensive phylogenetic analyses and species descriptions according to taxonomic standards for Recent organisms. We found well-preserved three-dimensional anatomy in mineralized arthropods from Paleogene fissure fillings and demonstrate the value of these fossils by utilizing digitally reconstructed anatomical structure of a hister beetle. The new anatomical data facilitate a refinement of the species diagnosis and allowed us to reject a previous hypothesis of close phylogenetic relationship to an extant congeneric species. Our findings suggest that mineralized fossils, even those of macroscopically poor preservation, constitute a rich but yet largely unexploited source of anatomical data for fossil arthropods.

Abstract
The formely monotypic Neotropical genus Megalocraerus Lewis is revised to include five species, known from southeastern Brazil to Costa Rica: Megalocraerus rubricatus Lewis, Megalocraerus mandibularis sp. n., Megalocraerus chico sp. n., Megalocraerus madrededios sp. n., and Megalocraerus tiputini sp. n. We describe the species, map their distributions, and provide a key for their identification. Their subcylindrical body form and emarginate mesosternum have previously hindered placement to tribe, although their curent assignment to Exosternini now appears well supported by morphological evidence. Nothing is known of the natural history of the species.

Abstract
Here we present a complete revision of the species of Baconia. Up until now there have been 27 species assigned to the genus (Mazur, 2011), in two subgenera (Binhister Cooman and Baconia s. str.), with species in the Neotropical, Nearctic, Palaearctic, and Oriental regions. We recognize all these species as valid and correctly assigned to the genus, and redescribe all of them. We synonymize Binhister, previously used for a polyphyletic assemblage of species with varied relationships in the genus. We move four species into Baconia from other genera, and describe 85 species as new, bringing the total for the genus to 116 species. We divide these into 12 informal species groups, leaving 13 species unplaced to group. We present keys and diagnoses for all species, as well as habitus photos and illustrations of male genitalia for nearly all. The genus now contains the following species and species groups: Baconia loricata group [Baconia loricata Lewis, 1885, B. patula Lewis, 1885, Baconia gounellei (Marseul, 1887a), Baconia jubaris (Lewis, 1901), Baconia festiva (Lewis, 1891), Baconia foliosomasp. n., Baconia sapphirinasp. n., Baconia furtivasp. n., Baconia pernixsp. n., Baconia applanatissp. n., Baconia disciformissp. n., Baconia nebulosasp. n., Baconia brunneasp. n.], Baconia godmani group [Baconia godmani (Lewis, 1888), Baconia venusta (J.

Abstract
We revise the large Neotropical genus Operclipygus Marseul, in the histerid tribe Exosternini (Histeridae: Histerinae). We synonymize 3 species, move 14 species from other genera, sink the genus Tribalister Horn into Operclipygus, and describe 138 species as new, bringing the total to 177 species of Operclipygus. Keys are provided for the identification of all species, and the majority of the species are illustrated by habitus and male genitalia illustrations. The species are diverse throughout tropical South and Central America, with only a few species extending into the temperate parts of North America. The majority of species can be recognized by the presence of a distinct stria or sulcus along the apical margin of the pygidium, though it is not exclusive to the genus. Natural history details for species of Operclipygus are scant, as most specimens have been collected through the use of passive flight interception traps. Many are probably generally associated with decaying vegetation and leaf litter, where they prey on small arthropods. But a small proportion are known inquilines, with social insects such as ants and termites, and also with some burrowing mammals, such as Ctenomys Blainville. The genus now includes the following species groups and species: Operclipygus sulcistrius group [Operclipygus lucanoidessp. n., Operclipygus schmidtisp. n., Operclipygus simplistriussp. n.,

Abstract
We revise the genus Mecistostethus Marseul, sinking the monotypic genus Tarsilister Bruch as a junior synonym. Mecistostethus contains six valid species: Mecistostethus pilifer Marseul, Mecistostethus loretoensis (Bruch), comb. n., Mecistostethus seagorumsp. n., Mecistostethus carltonisp. n., Mecistostethus marseulisp. n., and Mecistostethus flechtmannisp. n. The few existing records show the genus to be widespread in tropical and subtropical South America, from northern Argentina to western Amazonian Ecuador and French Guiana. Only a single host record associates one species with the ant Pachycondyla striata Smith (Formicidae: Ponerinae), but it is possible that related ants host all the species.

Abstract
We revise the four species of Kaszabister Mazur, 1972, one of which, Kaszabister barrigaisp. n., is described as new. The other species in the genus are Kaszabister rubellus (Erichson, 1834), Kaszabister ferrugineus (Kirsch, 1873) and Kaszabister carinatus (Lewis, 1888). The species are principally known from the subtropics of South America, with one in Central America. Lectotypes are designated for Kaszabister rubellus and Kaszabister ferrugineus, and a key is provided for all the species. Ants of the genus Solenopsis Westwood, mainly Solenopsis invicta Buren and Solenopsis saevissima (Smith), are documented as hosts of three of the four species.

Abstract
The genus Oropodes is characterized and revised with 18 species being treated. Members of this genus are found in temperate forests to desert brush lands from Oregon to Baja California, but are associated primarily with dry forests and shrub lands of California. Keys to males and females, where known, are provided. Seven species are redescribed: Oropodes arcaps (California), Oropodes dybasi (Oregon), Oropodes ishii (California), Oropodes nuclere (California), Oropodes orbiceps (California), Oropodes rumseyensis (California), Oropodes yollabolly (California). The name Oropodes raffrayi (California) is raised from synonymy and the species is redescribed, NEW STATUS. Ten new species are described: Oropodes aalbui (California), Oropodes bellorum (California), Oropodes casson (California), Oropodes chumash (California), Oropodes esselen (California), Oropodes hardyi (California), Oropodes serrano (California), Oropodes tataviam (California), Oropodes tongva (California), and Oropodes tipai (Baja California, Mexico), NEW SPECIES. These species are placed into three species groups: the arcaps-group, the orbiceps-group, and the raffrayi-group. Data for a new record of Euplecterga fideli are given, and a list of the unassociated Oropodes females with distinctive genitalia is included with their label data.

Abstract
BACKGROUND Comparative phylogeography of sympatric sibling species provides an opportunity to isolate the effects of geography and demographics on the evolutionary history of two lineages over the same, known time scale. In the current study, we investigated the phylogeographic structure of two zopherid beetle species, Phloeodes diabolicus and P. plicatus, where their ranges overlap in California's Transverse Ranges. RESULTS Although P. diabolicus and P. plicatus share similar habitats with largely overlapping distributions, the results of this study revealed different evolutionary histories for each species since divergence from their most recent common ancestor. In general, P. plicatus had higher genetic diversity, and more among population isolation than P. diabolicus. The mismatch distributions indicated that one major difference between the two species was the timing of population expansion. This result was consistent with genetic patterns revealed by the Phist values and genetic diversity. Lastly, there were no parallel genetic breaks at similar geographic barriers between the species. CONCLUSIONS Our data revealed that differential demographics rather than geography were responsible for the genetic patterns of the two species.

Abstract
Beetles represent almost one-fourth of all described species, and knowledge about their relationships and evolution adds to our understanding of biodiversity. We performed a comprehensive phylogenetic analysis of Coleoptera inferred from three genes and nearly 1900 species, representing more than 80% of the world's recognized beetle families. We defined basal relationships in the Polyphaga supergroup, which contains over 300,000 species, and established five families as the earliest branching lineages. By dating the phylogeny, we found that the success of beetles is explained neither by exceptional net diversification rates nor by a predominant role of herbivory and the Cretaceous rise of angiosperms. Instead, the pre-Cretaceous origin of more than 100 present-day lineages suggests that beetle species richness is due to high survival of lineages and sustained diversification in a variety of niches.

Abstract
The Transverse Ranges in southern California have been identified as having a prominent phylogeographic role. Numerous studies have identified distinct north-south and/or east-west lineage breaks involving the Transverse Ranges. However, in evaluating their findings, most authors have regarded this complex system somewhat simplistically. In this study we more deeply investigate these breaks using two approaches: first we examine the phylogeographic history of Sepedophilus castaneus (Coleoptera: Staphylinidae) and then implement a comparative phylogeography approach applying Brooks parsimony analysis to the topologies of nine additional taxa. Phylogenetic analysis, nested clade analysis, and AMOVAs for S. castaneus agree that there is a major lineage break between the eastern and western Transverse Ranges, localized between the Sierra Pelona and the San Gabriel Mountains. The comparative phylogeographic analysis supports a generally strong concordance of area relationships with geographic proximity. It is notable, however, that the Transverse Ranges as a group do not show phylogenetic cohesion, but rather they are split into three main regions: an eastern region (San Gabriel, San Bernardino, and San Jacinto Mountains), a central region (central Transverse Ranges and Sierra Pelona) that is often grouped with the Tehachapi and Sierra Nevada populations, and a western region (northwestern Transverse Ranges and Santa Ynez Mountains) that is consistently grouped with coast range areas to the north. The lineage break between east and west Transverse Ranges is attributable to the presence of a marine embayment in what is now the Santa Clara River valley 5-2.5 million years ago.

Abstract
The histerid subfamily Chlamydopsinae is a clade of obligate inquilines of social insects, mainly ants. They show a wide range of bizarre morphological characteristics, including highly varied trichomes, associated with this lifestyle. They occur throughout Australia and Indomalaysia, with a few species occurring as far from this centre of diversity as India and Japan. At present the subfamily contains 12 genera and 174 species, several of which are newly described herein (Teretriopsis theryi, gen. nov., sp. nov., Papuopsis andersoni, gen. nov., sp. nov. and Quasimodopsis riedeli, gen. nov. sp. nov.). This paper presents a phylogenetic analysis based on morphological characters of all of the main lineages of the family, provides a complete catalogue of the species, a key to all the genera, and proposes several new combinations. The phylogenetic analysis reveals two large clades, one (including the genera Chlamydopsis Westwood, Eucurtia Mjöberg, and Ectatommiphila Lea) is largely restricted to the Australian continent, whereas the other, containing all other genera, is much more widespread, including many Australian species, but extending also through Indomalaysia into south-east Asia. The beetles are known to utilise many hosts, including ants in four different subfamilies (Myrmicinae, Ponerinae, Dolichoderinae, and Formicinae), as well as termites in the genus Eutermes. However, host records are not yet sufficiently comprehensive to exhibit any clear phylogenetic signal.

Abstract
The Staphyliniformia is one of the most diverse lineages of Coleoptera, with representatives occupying every conceivable non-marine niche. Phylogenetic relationships among its varied families and lower taxa have defied resolution. The problem has been further complicated by the recent suggestion that another major coleopteran series, Scarabaeiformia, is derived from within it. Here we present the first phylogenetic analyses, based on 18S rDNA sequences and morphological data, to explicitly examine this possibility. Thorough evaluation of alternative alignments and tree construction methods support the contention that Scarabaeiformia is derived from within Staphyliniformia. Though the analyses yielded strong support for few family level groupings within the expanded Staphyliniformia, they conclusively support a close relationship between Hydraenidae and Ptiliidae, which has often been debated. The primary factor hindering additional resolution appears to be the inconsistent rate of divergence in 18S among these taxa.

Abstract
Swallowtail butterflies are recognized as model organisms in ecology, evolutionary biology, genetics, and conservation biology but present numerous unresolved phylogenetic problems. We inferred phylogenetic relationships for 51 of about 205 species of the genus Papilio (sensu lato) from 3.3-Kilobase (kb) sequences of mitochondrial and nuclear DNA (2.3 kb of cytochrome oxidases I and II and 1.0 kb of elongation factor 1 alpha). Congruent phylogenetic trees were recovered within Papilio from analyses of combined data using maximum likelihood, Bayesian analysis, and maximum parsimony bootstrap consensus. Several disagreements with the traditional classification of Papilio were found. Five major previously hypothesized subdivisions within Papilio were well supported: Heraclides, Pterourus, Chilasa, Papilio (sensu stricto), and Eleppone. Further studies are required to clarify relationships within traditional "Princeps," which was paraphyletic. Several biologically interesting characteristics of Papilio appear to have polyphyletic origins, including mimetic adults, larval host associations, and larval morphology. Early diversification within Papilio is estimated at 55-65 million years ago based on a combination of biogeographic time constraints rather than fossils. This divergence time suggests that Papilio has slower apparent substitution rates than do Drosophila and fig-pollinating wasps and/or divergences corrected using best-fit substitution models are still being consistently underestimated. The amount of sequence divergence between Papilio subdivisions is equivalent to divergences between genera in other tribes of the Papilionidae, and between genera of moths of the noctuid subfamily Heliothinae.

Abstract
Although it is widely agreed that data from multiple sources are necessary to confidently resolve phylogenetic relationships, procedures for accommodating and incorporating heterogeneity in such data remain underdeveloped. We explored the use of partitioned, model-based analyses of heterogeneous molecular data in the context of a phylogenetic study of swallowtail butterflies (Lepidoptera: Papilionidae). Despite substantial basic and applied study, phylogenetic relationships among the major lineages of this prominent group remain contentious. We sequenced 3.3 kb of mitochondrial and nuclear DNA (2.3 kb of cytochrome oxidase I and II and 1.0 kb of elongation factor-1 alpha, respectively) from 22 swallowtails, including representatives of Baroniinae, Parnassiinae, and Papilioninae, and from several moth and butterfly outgroups. Using parsimony, we encountered considerable difficulty in resolving the deepest splits among these taxa. We therefore chose two outgroups with undisputed relationships to each other and to Papilionidae and undertook detailed likelihood analyses of alternative topologies. Following from previous studies that have demonstrated substantial heterogeneity in the evolutionary dynamics among process partitions of these genes, we estimated evolutionary parameters separately for gene-based and codon-based partitions. These values were then used as the basis for examining the likelihoods of possible resolutions and rootings under several partitioned and unpartitioned likelihood models. Partitioned models gave markedly better fits to the data than did unpartitioned models and supported different topologies. However, the most likely topology varied from model to model. The most likely ingroup topology under the best-fitting, six-partition GTR + gamma model favors a paraphyletic Parnassiinae. However, when examining the likelihoods of alternative rootings of this tree relative to rootings of the classical hypothesis, two rootings of the latter emerge as most likely. Of these two, the most likely rooting is within the Papilioninae, although a rooting between Baronia and the remaining Papilionidae is only nonsignificantly less likely.

Abstract
Insect molecular systematics has undergone remarkable recent growth. Advances in methods of data generation and analysis have led to the accumulation of large amounts of DNA sequence data from most major insect groups. In addition to reviewing theoretical and methodological advances, we have compiled information on the taxa and regions sequenced from all available phylogenetic studies of insects. It is evident that investigators have not usually coordinated their efforts. The genes and regions that have been sequenced differ substantially among studies and the whole of our efforts is thus little greater than the sum of its parts. The cytochrome oxidase I, 16S, 18S, and elongation factor-1 alpha genes have been widely used and are informative across a broad range of divergences in insects. We advocate their use as standards for insect phylogenetics. Insect molecular systematics has complemented and enhanced the value of morphological and ecological data, making substantial contributions to evolutionary biology in the process. A more coordinated approach focused on gathering homologous sequence data will greatly facilitate such efforts.

Abstract
Butterflies of the genus Papilio have served as the basis for numerous studies in insect physiology, genetics, and ecology. However, phylogenetic work on relationships among major lineages in the genus has been limited and inconclusive. We have sequenced 2.3 kb of DNA from the mitochondrial cytochrome oxidase I and II genes (COI and COII) for 23 Papilio taxa and two outgroups, Pachliopta neptunus and Eurytides marcellus, in order to assess the potential of these genes for use in Papilio phylogenetics and to examine patterns of gene evolution across a broad taxonomic range. Nucleotide and amino acid variation is distributed heterogeneously, both within and between genes. Structural features of the proteins are not always reliable predictors of variation. In a combined analysis, these sequences support a nearly fully resolved topology within subgenera and species groups, though higher level relationships among species groups require additional study. The most noteworthy findings are that neither Papilio alexanor nor P. xuthus belongs in the machaon group and that the subgenus Pterourus is paraphyletic with respect to the subgenus Pyrrhosticta. We leave relationships among members of the phorcas species group as a trichotomy. These two protein coding genes, particularly COI, show excellent performance in resolving relationships at the level of species and species groups among Papilionidae. We strongly endorse a similar approach for future studies aimed at these levels.
