Etymology: Hemibagrus: Greek, hemi = the half + Mozarabic, bagre, Greek, pagros = a fish, Dentex sp. (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 Morfologia | Morfometria

Spine dorsali (totale): 2; Raggi dorsali molli (totale): 7; Raggi anali molli: 12 - 13; Vertebre: 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).

Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00438 - 0.02182), b=3.00 (2.82 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.6 se; based on size and trophs of closest relatives
Resilienza (Ref. 120179):  Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (45 of 100) .
