臀鳍软条: 98 - 108; 脊椎骨: 62 - 65. Snout with a steep ventral profile (ventral angle of snout 20°-26°), relatively more anal-fin rays (98-108), and smaller eyes (eye diameter 10.7% - 14.0% HL) that are set further apart (interorbital distance 35.4 - 40.9% HL). Mature males have membranous extensions on only the anterior edge of the maxillary barbel.
吻部有一个陡峭的腹轮廓 (吻的腹面角 20 °-26 °) ，相对较多的臀鳍棘条 (98-108) 与较小的眼 (眼直径 10.7%- 14.0% HL) 分别地那是组进一步 (眼间距 35.4- 40.9% HL). 成熟的雄鱼在只有颚触须的前缘上有膜状的延长。
In Kapuas Lakes area in Kalimantan Barat, Indonesia, fishermen reported that this species inhabits rivers and major streams with moderate to fast current (Ref. 56749). Appears to be predatory in nature, feeding on aquatic invertebrates (Ref. 38651) and fish (Ref. 56749).
