Short description
Identification keys | Morphology | Morphometrics
Belongs to the Hypsolebias antenori species group, differing from all congeners of this group by having a rudimentary squamation on the supra-orbital region, a unique color pattern on the caudal fin in males consisting of white dots arranged in transverse rows, 14 scale rows around the caudal peduncle, the dorsal fin slightly more posteriorly placed in males and the basihyal bone narrow (Ref. 88806).

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): 3.2 ±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).
