Systematics and diversification of the Ichthyomyini (Cricetidae, Sigmodontinae) revisited: evidence from molecular, morphological, and combined approaches. PeerJ 2023; 11:e14319.

Abstract
Ichthyomyini, a morphologically distinctive group of Neotropical cricetid rodents, lacks an integrative study of its systematics and biogeography. Since this tribe is a crucial element of the Sigmodontinae, the most speciose subfamily of the Cricetidae, we conducted a study that includes most of its recognized diversity (five genera and 19 species distributed from southern Mexico to northern Bolivia). For this report we analyzed a combined matrix composed of four molecular markers (RBP3, GHR, RAG1, Cytb) and 56 morphological traits, the latter including 15 external, 14 cranial, 19 dental, five soft-anatomical and three postcranial features. A variety of results were obtained, some of which are inconsistent with the currently accepted classification and understanding of the tribe. Ichthyomyini is retrieved as monophyletic, and it is divided into two main clades that are here recognized as subtribes: one to contain the genus Anotomys and the other composed by the remaining genera. Neusticomys (as currently recognized) was found to consist of two well supported clades, one of which corresponds to the original concept of Daptomys. Accordingly, we propose the resurrection of the latter as a valid genus to include several species from low to middle elevations and restrict Neusticomys to several highland forms. Numerous other revisions are necessary to reconcile the alpha taxonomy of ichthyomyines with our phylogenetic results, including placement of the Cajas Plateau water rat (formerly Chibchanomys orcesi) in the genus Neusticomys (sensu stricto), and the recognition of at least two new species (one in Neusticomys, one in Daptomys). Additional work is necessary to confirm other unanticipated results, such as the non-monophyletic nature of Rheomys and the presence of a possible new genus and species from Peru. Our results also suggest that ichthyomyines are one of the main Andean radiations of sigmodontine cricetids, with an evolutionary history dating to the Late Miocene and subsequent cladogenesis during the Pleistocene.

Abstract
Abstract
Background
For the genus Thylamys, the rivers have been reported as barriers to dispersal, limiting current and historical distribution of its lineages. We hypothesized that the Maipo river has affected the genetic structure of northern and southern lineages of Thylamys elegans, recovering a phylogenetic relationships with reciprocally monophyletic sister groups on opposite river banks. We evaluated the role of other rivers in the Mediterranean zone of Chile as historical and recent modulators of the biogeographic processes of this species.
Methods
We applied a phylogeographic approach, using the cytochrome-b mitochondrial gene for 93 individuals of T. elegans, from 37 localities in a latitudinal gradient between 21°25’ and 35˚56’S, encompassing a geographic area between the Atacama Desert and most of the Mediterranean Chilean zone.
Results
The phylogenetics results recovered six lineages within T. elegans: Thylamys elegans elegans, Thylamys elegans coquimbensis, the Loa lineage and three other lineages not described previously (Aconcagua, South 1 and South 2). We suggest that following rivers play a role like primary barrier: the Maipo river in the genetic differentiation of northern and southern ancestral lineages, and the Mataquito river and its tributary Teno river for the South 1 and South 2 lineages. On the other hand, the Quilimarí river preserve the genetic divergence in T. e. coquimbensis and Aconcagua lineage and the Aconcagua river in Aconcagua lineage and T. e. elegans acting like secondary barriers.
Conclusions
We concluded that the genetic diversity and biogeographic history of T. elegans was shaped by mountain glaciers, changes in river water levels during the Pleistocene glaciations and hyperaridity, promoting the differentiation and persistance of the T. elegans lineages.

Abstract
Systematic revisions of South American marsupials have contributed to our knowledge about genus and species diversity in the last decades, including studies of the most recently described genus Cryptonanus (Didelphidae), currently comprising four recognized species. Herein we provide the first phylogeny for these mouse opossums based on comprehensive sampling, including representatives from all nominal taxa, encompassing most of the geographic distribution of the genus while also extending its known range. The taxonomic status of Cryptonanus species was explored by analyses of multiple mitochondrial and nuclear DNA markers to assess phylogenetic relationships and to provide divergence time estimates, species delimitations and biogeographical hypotheses. Cryptonanus monophyly remained highly supported despite the inclusion of abundant new data from more than a hundred specimens, comprising 10 independent evolutionary lineages. Species-complexes within valid nominal taxa reveal higher species richness in the genus. Based on divergence estimates from a dated phylogeny, we suggest that Cryptonanus diversified along the Quaternary, with speciation events occurring well into the Pleistocene. The best supported biogeographical hypothesis endorses speciation by vicariance and subset speciation across open formations in shaping the evolutionary history of this didelphid genus, strongly associated with dry tropical landscapes of South America.

Abstract
Cytochrome b sequences from South American specimens of the water opossum Chironectes minimus exhibit uncorrected pairwise differences of 0.6% or less among samples collected thousands of kilometers apart (in Guyana, Bolivia and southeastern Brazil). Despite published evidence of population divergence from recent analyses of craniodental morphology, our results suggest extensive gene flow or recent range expansion across the South American landscapes currently occupied by this seldom-collected species.

Abstract
Abstract
Knowledge about the feeding ecology of didelphid marsupials remains incipient, especially in environments with marked seasonality in resource supply, such as in the Cerrado. We analysed the diet composition of Thylamys macrurus in Cerrado patches in central-western Brazil. We also evaluated seasonal and sexual variation in the species’ diet, as well as if the accumulation of fat in the tail shows a seasonal pattern. We obtained 87 captures of 68 T. macrurus specimens and 29 faecal samples. Six categories of food items (Hymenoptera, Isoptera, Coleoptera, Arachnida, Blattodea and seeds) were identified. Arthropods were recorded in all samples and seeds in 10.3%. The species showed seasonal variation in diet, consuming primarily of arthropods throughout the year but incorporating a higher proportion of fruits during the wet season. Males and females also differed in diet composition; males consumed a wider range of items in the dry season. Although more detailed analyses are still needed to better understand the T. macrurus food consumption pattern, our results indicate a possible relationship between dietary variation and local availability of resources, suggesting an opportunistic foraging pattern. The accumulation of fat in the tail also presents a seasonal pattern, with a larger tail diameter in the dry season.

Abstract
Abstract
In this note, I discuss the advantages of the usage of subgenera as a practical taxonomic rank in mammalian taxonomy. Use of this category preserves traditional usage, reduces nomenclatural instability and avoids unnecessary change of names. Subgenera are useful to label diagnosable clades of closely related species, especially in morphologically and ecologically diverse monophyletic genera, without alteration of traditional binomial usage. Contrary to informal names such as “divisions” or “groups”, subgenera are governed by the rules of the International Commission on Zoological Nomenclature (ICZN), having usage constrained (and stability promoted) by typification and priority.

Abstract
The taxonomy of American deer has been established almost entirely on the basis of morphological data and without the use of explicit phylogenetic methods; hence, phylogenetic analyses including data for all of the currently recognized species, even if based on a single gene, might improve current understanding of their taxonomy. We tested the monophyly of the morphology-defined genera and species of New World deer (Odocoileini) with phylogenetic analyses of mitochondrial DNA sequences. This is the first such test conducted using extensive geographic and taxonomic sampling. Our results do not support the monophyly of Mazama, Odocoileus, Pudu, M. americana, M. nemorivaga, Od. hemionus, and Od. virginianus. Mazama contains species that belong to other genera. We found a novel sister-taxon relationship between "Mazama" pandora and a clade formed by Od. hemionus columbianus and Od. h. sitkensis, and transfer pandora to Odocoileus. The clade formed by Od. h. columbianus and Od. h. sitkensis may represent a valid species, whereas the remaining subspecies of Od. hemionus appear closer to Od. virginianus. Pudu (Pudu) puda was not found sister to Pudu (Pudella) mephistophiles. If confirmed, this result will prompt the recognition of the monotypic Pudella as a distinct genus. We provide evidence for the existence of an undescribed species now confused with Mazama americana, and identify other instances of cryptic, taxonomically unrecognized species-level diversity among populations here regarded as Mazama temama, "Mazama" nemorivaga, and Hippocamelus antisensis. Noteworthy records that substantially extend the known distributions of M. temama and "M." gouazoubira are provided, and we unveil a surprising ambiguity regarding the distribution of "M." nemorivaga, as it is described in the literature. The study of deer of the tribe Odocoileini has been hampered by the paucity of information regarding voucher specimens and the provenance of sequences deposited in GenBank. We pinpoint priorities for future systematic research on the tribe Odocoileini.

Abstract
We undertook a comprehensive, critical review of literature concerning the distribution, conservation status, and taxonomy of species of mammals endemic to the Cerrado and the Caatinga, the two largest biomes of the South American Dry-Diagonal. We present species accounts and lists of species, which we built with criteria that, in our opinion, yielded results with increased scientific rigor relative to previously published lists - e.g., excluding nominal taxa whose statuses as species have been claimed only on the basis of unpublished data, incomplete taxonomic work, or weak evidence. For various taxa, we provided arguments regarding species distributions, conservation and taxonomic statuses previously lacking in the literature. Two major findings are worth highlighting. First, we unveil the existence of a group of species endemic to both the Cerrado and the Caatinga (i.e., present in both biomes and absent in all other biomes). From the biogeographic point of view, this group, herein referred to as Caatinga-Cerrado endemics, deserves attention as a unit - just as in case of the Caatinga-only and the Cerrado-only endemics. We present preliminary hypotheses on the origin of these three endemic faunas (Cerrado-only, Caatinga-only, and Caatinga-Cerrado endemics). Secondly, we discovered that a substantial portion of the endemic mammalian faunas of the Caatinga and the Cerrado faces risks of extinction that are unrecognized in the highly influential Red List of Threatened Species published by the International Union for Conservation of Nature (IUCN). "Data deficient" is a category that misrepresents the real risks of extinction of these species considering that (a) some of these species are known only from a handful of specimens collected in a single or a few localities long ago; (b) the Cerrado and the Caatinga have been sufficiently sampled to guarantee collection of additional specimens of these species if they were abundant; (c) natural habitats of the Cerrado and the Caatinga have been substantially altered or lost in recent decades. Failures either in the design of the IUCN criteria or in their application to assign categories of extinction risks represent an additional important threat to these endemic faunas because their real risks of extinctions become hidden. It is imperative to correct this situation, particularly considering that these species are associated to habitats that are experiencing fast transformation into areas for agriculture, at an unbearable cost for biodiversity.

Abstract
Abstract
A previous study showed that Dromiciops gliroides has deep phylogeographic structure, with 3 allopatric and highly differentiated groups. Here, we constructed on that study by assessing the morphologic variation of D. gliroides. Our results show that along its distribution Dromiciops is morphologically highly variable and that the geographic pattern of morphologic variation matches the phylogeographic pattern. Taken together, morphological and molecular data indicate the existence of 2 unrecognized and unnamed species of monito del monte, which are here named and described. Cranial and dental features can easily distinguish species of Dromiciops. One of the new species is endemic of Chile, and the other new species occurs in Argentina and Chile. D. gliroides s.s. is restricted to the southern part of the genus distribution including Chiloé Island. We comment on the conservation significance of our findings and on the need of continuing with field- and collection-based research in order to characterize the richness of the Chilean mammal assemblage.
Un estudio previo mostró que Dromiciops gliroides tiene una marcada estructura filogeográfica con 3 grupos alopátridos bien diferenciados. Dado esos resultados, en el presente estudio analizamos la variación morfológica de D. gliroides. Nuestros resultados indican que D. gliroides es, a través de su distribución, altamente variable y que el patrón geográfico de la variación morfológica es congruente con el patrón filogeografico. Considerada en conjunto, la evidencia morfológica y molecular indica la existencia de dos especies de monito del monte que no han sido reconocidas, las que son aca descritas y nominadas. Las tres especies de Dromiciops se pueden distinguir fácilmente por características craneales y dentales. Una de las nuevas especies es endémica de Chile y la otra se distribuye en Argentina y Chile. D. gliroides s.s. se restringe a la porción sur del área distribucional del género, incluyendo la Isla de Chiloé. Cerramos el trabajo comentado sobre la necesidad de continuar realizando colectas y trabajo basado en colecciones con el fin de caracterizar la diversidad del ensamble de mamíferos de Chile.

Abstract
Abstract
Morphological character data are inadequate to resolve the evolutionary relationships of the didelphid genus Chacodelphys , which previous phylogenetic analyses have alternatively suggested might be the sister taxon of Lestodelphys and Thylamys (tribe Thylamyini) or of Monodelphis (tribe Marmosini) in the subfamily Didelphinae. Because fresh material of Chacodelphys is unavailable, we extracted DNA from microscopic fragments of soft tissue adhering to the 95-year-old holotype skull of C. formosa. Phylogenetic analyses of the resulting sequence data convincingly resolve Chacodelphys as the sister taxon of Cryptonanus , a genus with which it had not previously been thought to be closely related. This novel clade ( Chacodelphys + Cryptonanus ) belongs to an unnamed thylamyine lineage with Gracilinanus and Lestodelphys + Thylamys , but relationships among these taxa remain to be convincingly resolved.
Los análisis basados en caracteres morfológicos han sido inadecuados para resolver las relaciones evolutivas del género marsupial didélfido Chacodelphys . Previos análisis filogenéticos han sugerido como hipótesis alternativas que Chacodelphys sea el grupo hermano de Lestodelphys y Thylamys (tribu Thylamyini) o de Monodelphis (tribu Marmosini), todos estos géneros pertenecientes a la subfamilia Didelphinae. Debido a la ausencia de material fresco de Chacodelphys , extrajimos ADN de fragmentos microscópicos de tejido adherido al cráneo de 95 años del holotipo de C. formosa . Análisis filogenéticos de las secuencias obtenidas resuelven convincentemente la posición filogenética de Chacodelphys como el taxón hermano de Cryptonanus , un género con el cual nunca antes se había pensado que estuviera cercanamente relacionado. Aunque reconocemos a este nuevo clado ( Chacodelphys + Cryptonanus ) junto con Gracilinanus y Lestodelphys + Thylamys pertenecientes a un linaje sin nombre, las relaciones entre estas taxa siguen sin estar convincentemente resueltas.
