(Ref. 45335);  divaricatus: Specific epithet is from the Latin 'divaricatus', meaning spread apart, in reference to the relatively large distance between the dorsal and adipose fins of this species..

Short description Morfología | Morfometría

Espinas dorsales (total): 2; Radios blandos dorsales (total): 7; Radios blandos anales: 12 - 13; Vértebra: 51. 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).

Bayesian length-weight: a=0.00977 (0.00440 - 0.02172), b=3.00 (2.82 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nivel trófico (Ref. 69278):  3.5   ±0.6 se; based on size and trophs of closest relatives
Resiliencia (Ref. 120179):  Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (28 of 100).
