deskripsi pendek
Kunci identifiaksi (pengenalan) | Morfologi | Morfometrik
duri punggung lunak (Keseluruhan (total)) : 7 - 8; Sirip dubur lunak: 15 - 19; vertebrata, bertulang belakang: 39. This species is distinguished from most congeners, except H. mikrostiktos, H. paez, H. tridens, and H. virolinica, by the number of branched anal-fin rays 15-19 (vs. 20-34); Hemibrycon beni differs from these species by the number of lateral line scales 44-53 (vs. 40-42, 39-42, 39, and 40-44, respectively). H. beni differs from H. virolinica by the number of predorsal scales 17-20 (vs. 10-15). H. beni when compared with H. helleri, overlap somewhat with branched anal-fin ray counts 15-19 (vs. 19-23 for the latter), but can be distinguished from each other by the size of humeral spot 3-4 horizontal series of scales and the total number of vertebrae 38-39 in H. beni (vs. 7-8 in horizontal series of scales and 41-43 vertebrae, respectively for H. helleri) (Ref. 85819).

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=0.00955 (0.00443 - 0.02057), b=3.06 (2.88 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.0 ±0.4 se; based on size and trophs of closest relatives
Daya lenting (Ref.
120179): Tinggi, Waktu penggandaan populasi minimum kurang dari 15 bulan (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
