Abstract

Sclerodorcinus Soares & Grossi new genus is described from the Peruvian Andes to include four species that had been classified in Sclerostomus Burmeister, 1847 and Metadorcinus Kriesche, 1922. Those species are Sclerodorcinus wendyae (Arnaud & Bomans, 2006) new combination, Sclerodorcinus. damasoi (Arnaud & Bomans, 2006) new combination, Sclerodorcinus. bartolozzi (Arnaud & Bomans, 2007) new combination, and Sclerodorcinus yamauchii (Arnaud, Noguchi & Bomans, 2007) new combination. Sclerostomus kirchneri Schenk 2006 is placed in synonymy with Sclerostomus wendyae Arnaud & Bomans, 2006. A species identification key and distribution map of known localities are provided for the new genus. Sclerodorcinus can be characterized by the absence of a ventral groove on the male mandibles, the absence of a temporal process in both sexes, the presence of a dorsal groove on the female mandibles, and the hexagonal shape of the dorsal plate of the genital capsule in males, with ventral plate being strongly sclerotized.
