Short description Identification keys | Morphology | Morphometrics

This species can be easily distinguished from its congeners by the following characters: presence of metallic golden-green, with 11-13 large light dark vertical bars in the flank; caudal fin translucent and has no dots; fewer number of pelvic fin rays; dorsal-fin origin through base of 8th or 9th anal fin ray; higher number of anterior rostral cephalic neuromasts; and, cylindrical and elongated urogenital papilla in males (Ref. 127992).

Known only from the type locality, in temporary pools of about 1.3 m deep. Commonly found co-existing with other annual fish species of the genus Hypsolebias. Maximum length based on type specimen, to be replaced with a better reference (Ref. 127992).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [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): 3.3 ±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).
