Dorsale zachte stralen (totaal): 13-16; Anale zachte stralen: 8 - 10. This species is distinguished from other members of the Hoplias lacerdae group by having the following characters: laterosensory canal along the ventral surface of dentary always with 4 pores that become gradually subdivided into four patches of multiple pores in specimens larger than 6 cm SL; head and body with a dark brown ground coloration; scales on the lateral line 34-39; snout width 13.1-27.2% of HL; and interorbital width 16.0-35.5% of HL. Differs from Hoplias brasiliensis and Hoplias intermedius by its anterior profile of head rounded in lateral view vs. angular (Ref. 81195).
Inhabits large rivers and igarapés. Occurs usually in pairs. Exhibits diurnal as well as nocturnal habits and preys on various insects, larvae, small fishes, shrimps, worms and fruits (Ref. 81195).
