Taxonomic note.

The holotype of Sadocus calcar is in a very bad state of preservation; only part of the carapace, with the ozopores, and leg IV remain. The rest of the prosoma and all of the other legs are absent. Even in this condition, we noted that S. calcar lacks the large tubercles and spines on the free tergites, which are diagnostic of Sadocus . Furthermore, the armature of trochanter IV and the long, bifid, C-shaped dorso-basal apophysis on femur IV are strikingly similar to those of Gonyleptes horridus , a common species in the state of Rio de Janeiro. Therefore, we propose S. calcar as a junior synonym of G. horridus . This synonymy made us conclude that the provenance of S. calcar is mistaken, because G. horridus is endemic to the Brazilian Atlantic rainforest. It is widely known that Roewer, unfortunately, indicated wrong provenance of a few species, and this seems to be the case for this species.
