Tribe Oxypodini Thomson, 1859 Oxypodides Thomson 1859: 36 (ICZN, 1957: Name No. 150). Oxypodini: Seevers 1978: 14; Newton and Thayer 1992: 53; Ashe 2001: 360; Klimaszewski and Winchester 2002: 54; Klimaszewski and Pelletier 2004: 447; Klimaszewski et al. 2005: 9. Type genus: Oxypoda Mannerheim 1830: 69 (ICZN, 1957: Name No. 1078). Diagnosis Adults. Structurally diverse group of aleocharine beetles that may be recognized by the following combination of characters: tarsal formula usually 5-5-5 but in some taxa 4-5-5 or 4-4-4, mouthparts generalized, mesocoxae moderately to narrowly separated and with slender and often sharply pointed mesoventral process; acetabula usually margined; pronotal hypomera not visible laterally in some genera (e.g. Oxypoda and close allies); abdominal tergite 9 narrowly subdivided at base (Seevers 1978); median lobe of aedeagus with an elongate compressor plate and without an “athetine bridge” (Seevers 1978); paramerite usually with elongate apical lobe and striated velum. There are 48 genera in 5 subtribes in North America (Ashe 2001) and 24 genera in 3 subtribes in Canada and Alaska (Gouix and Klimaszewski 2007). At the present time the placement of the genus Gnypeta in the tribe Oxypodini should be considered as a tentative arrangement due to existing controversy between different authors and the lack of comprehensive analysis at the tribal level (see discussion under Phylogenetic affiliations).
