Conchomorphological and anatomic characteristics of species from Punctum (Toltecia) are presented and discussed. The brief recharacterization about the conchomorphology and internal anatomy of Toltecia with related species from this subgenus is presented. The data from this species are compared with other related species from Punctidae, Helicodiscidae and Charopidae. Punctum (Toltecia) pilsbryi, n.comb. is redescribed and its shells features was analyzed by SEM (Scanning Electron Microscope) and commented, as well as the shells dimensions; the anatomy of the excretory and reproductive systems are described too. The anatomic characteristics, mainly from excretory system, characterize Punctum (Toltecia) pilsbryi, n.comb. like Punctidae.
