Etymology: Brycinus: Greek, ebrykon, brykomai = to bite, to gnaw (Ref. 45335); epuluensis: The Latin adjective epuluensis refers to the type locality of the species, the Epulu River (Ref. 113515).

Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 0; Dorsal soft rays (total): 10; Anal spines: 0; Anal soft rays: 15 - 18; Vertebrae: 33 - 34. Diagnosis: Brycinus epuluensis is distinguished from all species belonging to the macrolepidotus group by having a short snout, more than 3 times in head length vs. less than 3 times, and fewer premaxillary teeth, 6-7 vs. 8-11; it is distinguished from all species belonging to the longipinnis group by the absence of a fronto-parietal fontanelle in adults vs. fronto-parietal fontanelle always present, fewer lateral line scales, 18-22 vs. 25-36, and generally fewer anal-fin rays, iii,12-15 vs. iii,14-25; it is distinguished from aal species of the nurse group by having 6 or exceptionally 7 premaxillary teeth vs. 8-10, exceptionally 7 (Ref. 113515). The species is most similar to Brycinus imberi, from which it is mainly distinguished by fewer premaxillary teeth, 6-7 vs. 7-8, fewer lateral line scales, 18-22 vs. 21-31, and the presence of a black mid-lateral band (Ref. 113515).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.1 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
