簡短描述
檢索表 | 型態特徵 | 形態測量圖
臀鰭軟條: 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.
吻部有一個陡峭的腹輪廓 (吻的腹面角 20 °-26 °) ，相對較多的臀鰭棘條 (98-108) 與較小的眼 (眼直徑 10.7%- 14.0% HL) 分別地那是組進一步 (眼間距 35.4- 40.9% HL). 成熟的雄魚在只有顎觸鬚的前緣上有膜狀的延長。
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).
