Abstract

The male holotype of Hapalopus nondescriptus Mello-Leitão, 1926 is redescribed, illustrated and compared with freshly collected specimens from the type locality. The only difference noted among the holotype and the new material concerns the development of the subapical keel. Its taxonomic position is reinterpreted and discussed, resulting in its transfer to the genus Vitalius Lucas, Silva Junior & Bertani, 1993, and thus making the new combination Vitalius nondescriptus (Mello-Leitão, 1926) comb. nov. The female is described for the first time and the morphological variations in two males, born from the female used in the description, is presented and illustrated. The male differs from those of other Vitalius species by the palpal bulb with short apical keel and bifid tibial spur with narrow prolateral branch and almost straight retrolateral branch. The female differs from those of other Vitalius species by urticating hair of 'type I' having the region 'a' shorter than region 'b'. Hapalopus nondescriptus has a confusing taxonomic history, since the holotype specimen was also used to describe another theraphosid species (Cyclosternum melloleitaoi Bücherl, Thimoteo & Lucas, 1971) which was, consequently, considered its objective synonym. Thus, we consider it a clear example of theraphosid taxonomical chaos. (AU)
