Morphology | Morphometrics
This species is distinguished from its congeners by the following set of characters: mouth subterminal, weakly oblique to nearly horizontal (less than or equal to 20° to midline of body); no maxillary barbels; edge of rostral cap is straight, no medial indent; flank immaculate, no longitudinal stripes; caudal peduncle immaculate, no spot; anterior 3/4 of caudal fin dusky, posterior hyaline; in life, pectoral, pelvic, and anal fins red or orange (Ref. 123185).
Seems to be restricted to marginal or temporary habitats, including roadside canals. Has never been seen in flowing water habitats. So far as known, it does not occur sympatrically with other species of the genus.
