Descripción breve
Claves de identificación | Morfología | Morfometría
Radios blandos dorsales (total) : 16 - 26; Radios blandos anales: 17 - 25; Vértebra: 27 - 29. Can be diagnosed from other species of the Austrolebias alexandri group by the following combination of characters: posterior margin of each pectoral fin in male reaching a vertical between base of second and fifth anal-fin rays (vs. between urogenital papilla and base of second anal-fin ray); origin of dorsal fin either on vertical through anal-fin origin or posterior to it (vs. anterior); and presence of vertical rows of light blue dots on entire flank in larger males (vs. light blue bars) (Ref. 57613).
Body shape (shape guide): elongated.
