Hemiquedius Casey, 1915

Hemiquedius Casey, 1915: 397, 399; Smetana 1971a (diagnosis, as ' Quediini '); Chatzimanolis et al. 2010 (as Staphylinini: Quediina); Brunke et al. 2016 (as Staphylinini: Acylophorina)

Diagnosis.

Hemiquedius can be readily recognized as a member of the subtribe Acylophorina by its elongate, non-lobed and cylindrical mid and hind tarsomeres, and the empodial setae of the hind tarsus, which is distinctly longer than that of the foretarsus. Within the subtribe, Hemiquedius has a unique habitus (Fig. 1A) but is also distinguished by a combination of: foretibia without distinct spines; at least sutural half of elytron lacking regular, evenly distributed setae; antennae non-geniculate; pronotum roughly parallel-sided.
