Beeria nematocera
(Casey, 1915)
Beeria is a of ( ) originally described as Philonthus nematocerus by Casey in 1915, later transferred to the Beeria by Hatch in 1957. The genus combines morphological characteristics of both Staphylinini and Quediini tribes, though its supports placement in Quediini. The species is known from western North America.

Identification
Beeria can be distinguished from other Quediini by the combination of characters linking Staphylinini and Quediini tribes, with prothoracic being particularly diagnostic. The was historically confused with Staphylinini subtribe Xanthopygi due to shared character states. -level identification requires examination of detailed morphological features described in the original taxonomic literature.
Distribution
Western North America: recorded from Alaska, British Columbia (Canada), Oregon, and Washington (USA).
Similar Taxa
- PhilonthusHistorical confusion due to original description of Beeria as Philonthus nematocerus; separated by prothoracic and tribal assignment to Quediini rather than Staphylinini.
- XanthopygiShared character states led to historical misplacement; Beeria differs in prothoracic structure and is properly assigned to Quediini.

Taxonomic History
The has undergone multiple taxonomic revisions. Originally described as Philonthus nematocerus by Casey in 1915, it was later made the species of the new Beeria by Hatch in 1957 as Beeria . The two names were synonymized with taking priority as the senior synonym. The subtribe Triacri, established by Bernhauer in 1931 within Quediini, was found to be identical with Xanthopygi within Staphylinini, contributing to historical confusion about Beeria's placement.
Generic Distinctiveness
Beeria exhibits a mosaic of characters from both Staphylinini and Quediini tribes, making its historically contentious. The prothoracic ultimately supported Quediini placement, though this required detailed comparative study of tribal diagnostic characters.
