Author: (Fink & Weitzman, 1974)
Remark: Redescribed in Fink & Weitzman (1974: 5). Malabarba (1998) and Malabarba & Weitzman (1999) discuss phylogenetic relationships and considered this species more related to Compsurini Cheirodontines than to <i>Odontostilbe</i> species. A new generic assignment is necessary for this species.
Comments: Inhabits stagnant puddles, ditches and creeks of low to moderate velocity, between 20 to 90 m elevation.  Herbivorous and feeds on "aufwuchs", diatoms, filamentous algae and seeds (Ref. 36880).
