Hemibagrus divaricatus Ng & Kottelat 2013

Distinguished from all members in this species group except Hemibagrus gracilis and Hemibagrus velox in possessing a shorter adipose-fin base (11.1-15.5% SL vs. 15.1-21.1); the adipose fin is also relatively deeper compared to all species except Hemibagrus planiceps (maximum height 1.9-3.2 times in length of base vs. 2.9-6.0). Can be diagnosed from Hemibagrus gracilis in having a deeper caudal peduncle (7.3-8.0% SL vs. 6.2-7.5) and a smaller eye (11-17% HL vs. 17-21); from Hemibagrus velox in having a deeper caudal peduncle (7.3-8.0% SL vs. 6.2-7.6) and shorter inner mandibular barbels (37-44% HL vs. 42-57); from Hemibagrus bongan in having a smaller eye (11-17% HL vs. 16-20); from Hemibagrus lacustrinus in having a shorter adipose-fin base (11.1-15.5% SL vs. 18.8-20.4), a longer dorsal to adipose distance (15.4-17.6% SL vs. 7.6-10.9; adpressed dorsal fin not reaching vs. reaching origin of adipose fi n), and smaller eye (11-17% HL vs. 17-19); and from Hemibagrus planiceps in having a smaller interorbital distance (28-32% HL vs. 32-37), longer dorsal spine (12.3-12.9% SL vs. 8.3-11.7) and maxillary barbels (214-250% HL vs. 148-220) (Ref. 93057).

Dorsal spines (total): 2; Dorsal soft rays (total): 7; Analsoft rays: 12 - 13; Vertebrae: 51
