Diagnosis |
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). |
