New distribution records for Canadian Aleocharinae (Coleoptera, Staphylinidae), and new synonymies for Trichiusa

Aleocharine rove beetles of New Hampshire, USA: new taxa and new records (Coleoptera, Staphylinidae, Aleocharinae)

Based on the specimens housed primarily in the University of New Hampshire Insect Collection (UNH) and the Canadian National Collection (CNC), we present here a comprehensive faunal review of aleocharine beetles of the state and provide new distribution and natural history data. We report 252 species from New Hampshire belonging to some 74 genera in 15 tribes; 159 of these constitute new New Hampshire state records (NSR), of which 37 (excluding new species and including 1 New York record) constitute new country distribution records (NCR) for the USA. In addition, we provide 36 new state records for ME, with 5 of these species not yet known from NH, seven new state records for MA, two new state records for PA and VT, and one each for CT, DE, MI, NC, NY (also a NCR), OH, and OK. One new genus, Belladonna Klimaszewski and Chandler is erected, and nine species are described as new to science (alphabetical order): Agaricomorpha hampshirensis Klimaszewski and Chandler, sp. n., Atheta ellisi Klimaszewski and Chandler sp. n, Atheta monroe Klimaszewski and Chandler, sp. n., Atheta struyvei Klimaszewski and Chandler sp. n, Belladonna barryi Klimaszewski and Chandler, sp. n., Belladonna fortieri Klimaszewski and Chandler, sp. n., Colusa smetanai Klimaszewski and Chandler, sp. n., Philhygra pinkhami Klimaszewski and Chandler sp. n., and P. pseudomagniceps Klimaszewski and Chandler, sp. n. Undescribed females of Aleochara daviesi Klimaszewski and Brunke, and Silusa langori Klimaszewski, are described and illustrated. Illustrations of Atheta (Tetropla) tubericauda Bernhauer are provided for the first time, based on a male from New Hampshire. A new combination is proposed for Atheta (Dimetrota) mcalpinei Klimaszewski and Webster.

Annotated checklist of the beetles (Coleoptera) of the California Channel Islands

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.

A review of Canadian and Alaskan species of the genera Clusiota Casey and Atheta Thomson, subgenus Microdota Mulsant & Rey (Coleoptera, Staphylinidae, Aleocharinae)

This paper treats 13 species of the subgenus Microdota Mulsant & Rey of Atheta Thomson and 3 species of the genus Clusiota Casey in Canada and Alaska. We report here 4 species new to science, and 3 new provincial records. The following species are new to science: Atheta (Microdota) curtipenis Klimaszewski & Webster, sp. n., Atheta (Microdota) formicaensis Klimaszewski & Webster, sp. n., Atheta (Microdota) macesi Klimaszewski & Webster, sp. n., and Clusiotagrandipenis Klimaszewski & Webster, sp. n. The new provincial records are: Atheta (Microdota) pseudosubtilis Klimaszewski & Langor, new to AB, and Atheta (Microdota) subtilis (Scriba), an adventive Palaearctic species new to North America, first reported in LB and NB. The two Clusiota Casey species are reviewed, and their distribution is revised. A female Clusiotaimpressicollis was discovered in Ontario and is illustrated here for the first time. A key to all Canadian species of the subgenus Microdota and genus Clusiota are provided. Atheta (Microdota) holmbergi Bernhauer and Atheta (Microdota) alesi Klimaszewski & Brunke are transferred here to the subgenus Dimetrota Mulsant & Rey.
