Diagnosis.

Gonyleptes is a genus composed of generally large species (dorsal scutum length longer than 8 mm), which males present femur IV with conspicuous armature and scutal areas I–III convex in lateral view. The penis presents ventral plate very convex and apex of ventral process serrate and semicircular. See taxonomical note below.

Taxonomical note.

Gonyleptes possesses 23 species and its habitus resembles other genera placed in Gonyleptinae . As Kury (2003) already suggested, the generic boundaries are not so clear cut. Collonychium is an objective synonym of Gonyleptes since both type species are synonymous. It can be only distinguished from related taxa, such as Geraeocormobius Holmberg, 1887, by a combination of unsatisfactory Roewerian characteristics. The composition of the genus below includes the changes proposed in this article.
