The adventive genus xantholinus Dejean (Coleoptera, Staphylinidae, Staphylininae) in North America: New records and a synthesis of distributional data

Abstract

New distributional and bionomic data are provided for species of the genus Xantholinus in North America. Xantholinus elegans (Olivier, 1795) (= X. jarrigei Coiffait, 1956) is recorded from North America for the first time, based on specimens collected in Ontario, Canada from 2007-2010. The armature of the internal sac of the aedeagus in situ is illustrated to aid in identification. Xantholinus linearis (Olivier, 1795), known previously from the Maritime Provinces of Canada and the eastern United States, is newly recorded from Ontario. Xantholinus longiventris Heer, 1839 is still only known from western North America. A key is provided to allow recognition of all three species.
