Genus Pygirhynchus Audinet-Serville, 1838: 260

See Brock et al. (2023) for a complete reference list

This genus occurs in the Atlantic Forest of Brazil. The locality of the transferred species is either known to be the Atlantic Forest or is simply “ Brazil ” but highly likely to be from the Atlantic Forest as well. The genus now contains 11 species. Ocnophila brevifemur syn. nov. has its types lost and was described from the same locality and in the same work as Ocnophila armata syn. nov., right after it, and both are here synonymized under Pygirhynchus bispinosus (Redtenbacher, 1906) . Furthermore, with the transfer of Pygirhynchus fortior comb. nov., the species Pygirhynchus carioca Piza, 1944 syn. nov. is synonymized under the former. Characteristics contained by the transferred species that allowed generic assignment are the following: large head, rugose and with strong vertex in female, smooth in male; tectiform and robust body; legs somewhat thick without spiniform strong setae in the carinae of tibia; similar morphology of teminalia, especially tergum X of the female declined and projected posteriorly, subgenital plate of the female projected, thorn pads of the male with dozens of small thorns.
