deskripsi pendek
Kunci identifiaksi (pengenalan) | Morfologi | Morfometrik
Duri punggung (Keseluruhan (total)) : 2; duri punggung lunak (Keseluruhan (total)) : 7; Sirip dubur lunak: 12 - 13; vertebrata, bertulang belakang: 43 - 44. Differs from Hemibagrus baramensis in having a greater dorsal to adipose distance
(8.2-10.2% SL vs. 4.7-8.6), an anal fi n with a straight distal margin, imparting a more rhomboidal appearance (vs. with a convex distal margin, imparting a more rounded appearance)
and the upper lobe of the caudal fin regularly tapering (vs. rounded posteriorly); from H. sabanus in having a smaller adipose fin located further away from the dorsal
fin (length of adipose-fin base 19.3-3.5% SL vs. 8.9-34.3; dorsal to adipose distance 8.2-10.6% SL vs. 1.2-4.4), a deeper caudal peduncle (depth 9.6-11.3% SL vs. 7.2-9.4), and a shorter outer mandibular barbel (81.9-120.1% HL vs. 127.5-162.1) (Ref. 93057).
Body shape (shape guide): fusiform / normal.
Inhabits slow-flowing streams with turbid water and a substrate of mud and gravel at elevation.
Feeds mainly on arthropods (Ref. 93057).
