Parapristella Géry, 1964b

This genus, with two recognized species, is distinguishable from Pristella mainly in having two rows of premaxillary teeth, resembling a Hemigrammus species with a higher number of maxillary teeth (Géry, 1977). Although both Hemigrammus and Pristella are herein included in the Tetragonopterinae, Parapristella does not share presumably apomorphic character-states with any of the genera included in this clade and it is maintained herein as incertae sedis.
