Short description Identification keys | Morphology | Morphometrics

This species, a member of the orthodus species-group of Astyanax, differs from other members of the group by the following characters: differs from othodus, villwocki, superbus, bopiensi, boliviensis, yariguies by the absence of a spot on the caudal peduncle; differs further from villwocki by having a short lateral stripe extending from the caudal spot and it does not extend anteriorly beyond a vertical through the origin of the anal fin (vs. lateral stripe extending anteriorly beyond a vertical through the origin of the anal fin; differs from A. bopiensis in having less teeth that do not cover more than a third of the length of the maxillary (vs. larger number of teeth covering more than two thirds of the maxillary); differs from A. moorii for dorsal-fin-hypural distance < 45% SL (vs. > 50), by dorsal-pectoral distance > 50% SL (vs. < 50), interorbital distance > 32% HL (vs. < 32), upper jaw length less < 35% HL (vs. > 40) (Ref. 119406).

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=0.01738 (0.00782 - 0.03863), b=3.06 (2.89 - 3.23), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.9   ±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).
