Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 15 - 25; Anal soft rays: 19 - 24; Vertebrae: 29 - 30. Distinguished from all members of Hypsolebias flavicaudatus complex by having a series of light golden to light blue short lines between the sub-distal portion of the dorsal-fin rays in males (vs. never a similar color pattern). The following combination of characters can be useful to diagnose from other members of the complex: 4-6 dorsal fin filaments, tips in much surpassing posterior margin of caudal fin; a triangular bluish white spot on the anterior portion of the dorsal-fin base in males; largest spot on the centre of the flank in females about equal to eye in size; pre-pelvic length 44.3-47.7% SL in males and 49.5-54.9% SL in females; anal-fin base in males 36.9-41.4% SL; head length in males 29.2-31.4% SL; body depth in males 37.9-40.4% SL; caudal peduncle depth in males 13.6-15.4% SL (Ref. 89836).

Occurs in seasonal swamps (Ref. 89836).

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=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), 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).
