This paper treats the discovery of new species and new records of Staphylinidae from the subfamilies Omaliinae, Proteininae, Tachyporinae, Oxytelinae, Scydmaeninae, Steninae, Euaesthetinae, Pseudopsinae, Paederinae, and Staphylininae for the province of New Brunswick and other provinces of Canada, and the USA. We report here two species new to science, three new North American records, nine new Canadian records, two new USA records, and 50 new provincial records. The following are the species new to science: Proteinus hughesi Webster & Davies, sp. n. and P. sweeneyi Webster & Klimaszewski, sp. n. (Proteininae). Sepedophilus immaculatus (Stephens) and Carpelimus erichsoni (Sharp), C. mundus (Sharp) are newly recorded from North America. New Canadian records are as follows: Carpelimus difficilis (Casey), C. gracilis (Mannerheim), C. lacustris (Notman), C. probus (Casey), C. pusillus (Gravenhorst), Carpelimus rivularis (Motschulsky), C. spretus (Casey), C. weissi (Notman) (Oxytelinae), and Edaphus lederi Eppelsheim (Euaesthetinae). This is the first record of the genus Edaphus for Canada. Bledius basalis LeConte and Carpelimus obesus (Kiesenwetter) (Oxytelinae) are removed from the faunal list of New Brunswick. Proteinus acadiensis Klimaszewski and P. pseudothomasi Klimaszewski are newly recorded from the USA and several provinces of Canada. Habitat data from New Brunswick are provided for most of the species treated in this contribution.
Plain Language Summary
Rove beetles are a very species-diverse family and occupy numerous microhabitats in forest ecosystems. This paper describes 62 species of rove beetles in several subfamilies, including two species new to science, one new North American record, seven new Canadian records, two new USA records, and 50 new provincial records. The two new species, previously unknown to science, Proteinus hughesi Webster & Davies, sp. n., and P. sweeneyi Webster & Klimaszewski, were named after Cory Hughes and Jon Sweeney, CFS employees whose research into improved methods of surveying for bark and wood-boring beetles resulted in the collection of a number of the rove beetle species reported in this paper. In most trapping studies, the “non-target” species collected in traps are ignored. However, we took advantage of the opportunity provided by our trap samples to identify non-target species in many beetle families, including the rove beetles, and thereby increase our knowledge of beetle species diversity and distribution in Canada. This information improves our knowledge of beetle fauna in Canada, i.e., the species that are present, their relative abundance, and the habitats in which they live. This information is critical if we want to measure changes that may occur in the future due to ecosystem disturbances.
