Sørensen (1884) described Gonyleptes bimaculatus from Brazil without any illustration. Roewer (1913) transferred it to Paragonyleptes Roewer, 1913. Kury (2003) synonymized the type species (Gonyleptes bicuspidatus Koch, 1839) of Paragonyleptes with Collonychium bicuspidatum Bertkau, 1880 and considered some species allocated in Paragonyleptes as Gonyleptinae incertae sedis, such as Gonyleptellus bimaculatus. The examination of Gonyleptellus bimaculatus from detailed photos of the holotype, which is reasonably well preserved, allowed us to recognize it as Gonyleptellus cancellatus, a well-known species from the Brazilian states of Rio de Janeiro and São Paulo (Serra da Bocaina mountain range). Therefore, Gonyleptellus cancellatus is a junior synonym of Gonyleptellus bimaculatus. The other species of Gonyleptellus is Gonyleptellus bufoninus (Mello-Leitão, 1949), known only by its original description, which lacks illustration and its type depository is unknown (Kury 2003).
