Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 17 - 23; Anal soft rays: 19 - 23; Vertebrae: 27 - 29. This species belongs to Hypsolebias antenori group but it differs from all other members by having a dark grey to black stripe on the distal margin of the dorsal fin in males (vs. stripe absent). It is similar to H. antenori and H. igneus, and distinguished from the remaining species of the genus, by the presence of a broad orangish red zone on the anal fin in males (vs. red zone absent). It can be diagnosed from H. antenori and H. igneus by having 11 scales in the transverse series (vs. 14) and 11 gill rakers on ventral portion of first branchial arch (vs. 13); from H. antenori by having longer filaments on the anal fin in males, reaching the posterior portion of the caudal fin (vs. reaching basal portion of the caudal fin); and from H. igneus by having 6 pelvic-fin rays (vs. 7) and 27 scales in the longitudinal series (vs. 29-30) (Ref. 94133)

Found in a seasonal pool (Ref. 94133).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00891 (0.00396 - 0.02008), b=3.14 (2.94 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-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).
