This species is distinguished by the following characters: infraorbital 2 expanded ventrally, adjacent to small, almost imperceptible, naked area between sphenotic, compound pterotic, opercle and preopercle; with a roughly oblique, elongate, dark brown blotches along body; large specimens with cranial fontanel completely occluded, leaving just a shallow fossae, delimited by frontal bones, and reaching
anterior tip of parieto-supraoccipital; absence of a black dot on the base of median caudal-fin rays and sexually dimorphic features inconspicuous, i.e. cheek
region similar in males and females, with only minute, scattered odontodes in the former, dorsal and pectoral fins of males slightly longer than in females; tip of snout roughly truncate (Ref. 138468).
Body shape (shape guide): elongated; Cross section: oval.
This species was found mainly in very small (0.5-2 m wide) and shallow streams (30-60 cm depth), with slow current water and surrounded by relatively preserved riparian vegetation; bottom was sandy, sometimes covered with a thin layer of mud or fallen leaves (although there were rocky bottom stretches in the same creeks, the species was never found there). The streams may have a small amount of submerged vegetation. Associated species collected along with this species were Astyanax eigenmanniorum, Cheirodon interruptus, Corydoras paleatus, Heptapterus mustelinus, H. sympterygium, Mimagoniates inequalis, Phalloceros caudimaculatus, Pseudobunocephalus iheringii, Rhamdia sp. and Scleronema sp. (Ref. 138468).
