Chiavi di identificazione | Morfologia | Morfometria
This species differs from all its congeners except Austrolebias bellottii, A. univentripinnis, A. melanoorus, by the having the urogenital papilla attached to the anal fin in males (vs. free from the anal fin); differs from A. bellottii, A. univentripinnis by having well-defined light blue bands contrasting with the sides of the body in adult males (vs. vertical rows of light blue dots); differs from A. melanoorus by the dark gray colouration of the distal portion of the anal fin in males (vs. black), pelvic-fins dark bluish green (observed in ventral view) and bases united at about 50-80% on their medial margins (vs. dark gray and united about 50% or less), pectoral-fins with iridescent blue sub-marginal band (vs. no sub-marginal band), and general colouration of the body bluish green (vs. grayish sky blue) (Ref. 119404).
