পৃষ্ঠীয় নরম পাখনা দন্ড (মোট ) : 8; পায়ূর নরম পাখনা্তুন্ড: 6. Diagnosed from its congeners by having reddish-brown tipped teeth. Can be differentiated also by the following combination of characters: 20-40 teeth on premaxillary and 15-38 on the dentary bones; 23-24 plates in longitudinal series; lateral line almost complete, represented by 19-22 perforated +1 or 2 non-perforated plates; dorsal surface of pectoral spine with
about five longitudinal series of odontodes; abdomen in adults (about 2.30 cm SL) entirely covered with large plates, two to four in lateral series between the tip of the cleithrum and pelvic-fin base; a large dark brown lateral stripe extending from tip of snout, through inferior orbit, to end of caudal peduncle; transverse dark bars very inconspicuous or absent (Ref. 75061).
Facultative air-breathing in the genus (Ref. 126274); Found in flat areas in creeks of headwaters of Rio Tapajós in places of shallow clear waters with low current and sandy substrate. The holotype of this species was encountered in a creek severely altered by human activities; alongside a trail with very shallow water, the margin deprived of vegetation at the opposite side of swampy area, where vegetation was mainly represented by Tipha and Grammineae (Ref. 75061).
