Max length : 8.5 cm SL maschio/sesso non determinato; (Ref. 12693)
Raggi dorsali molli (totale) : 12; Raggi anali molli: 8. A member of the group of species with complete or nearly complete lateral line, 8 1/2 branched dorsal rays, 9+8 branched caudal rays and no sexual dimorphism. Can be distinguished by the following characters: 13-14 bars on body, the anterior ones not conspicuously wider than posterior ones; maximum head width 16.6-17.4% SL; eye diameter 3.1-3.6% SL, 14-17% HL; interorbital width 7.3-7.8% SL, 35-36% HL (Ref. 39226). Its slender caudal peduncle (1.23-1.53 times longer than deep) and its color pattern distinguish it from any congener (Ref. 39226). Presence of a dark blotch at dorsal-fin origin; a faint blotch at base of posterior rays of dorsal fin; scales very sparse or absent in front of dorsal fin and on belly (Ref. 12693).
Inhabits streams and river backwaters at the driest time of the year (Ref. 39226). Frequently found in large rivers with stony bottom (Ref. 43281). A 5.92 cm SL female with ripe ovulae 1.4-1.6 mm in diameter (Ref. 39226). Not caught commercially (Ref. 12693).
