Description of Hydrosmectomorpha Klimaszewski and Webster, a new subgenus of Atheta C. G. Thomson, with three new Canadian species (Coleoptera: Staphylinidae: Aleocharinae)

Abstract

A new subgenus, Hydrosmectomorpha Klimaszewski and Webster, of the genus Atheta C. G. Thomson (Coleoptera: Staphylinidae: Aleocharinae) is erected to accommodate three new species and Atheta newfoundlandica (Klimaszewski and Langor). The new species are: Atheta (Hydrosmectomorpha) meduxnekeagensis Webster and Klimaszewski, new species; Atheta (Hydrosmectomorpha) quebecensis Webster and Klimaszewski, new species, Atheta (Hydrosmectomorpha) vincenti Webster and Klimaszewski, new species. The new species are described, illustrated, and a key is provided. Atheta newfoundlandica (Klimaszewski and Langor), was recently transferred from Hydrosmecta C.G. Thomson to an unspecified subgenus of Atheta. New habitat/collection data are presented for the treated species.
