Belongs to a clade that also includes Austrolebias viarius, A. arachan, A. adloffi, A. charrua, A. minuano, A. nigrofasciatus, A. vandenbergi, A. bellottii and A. melanoorus, which is diagnosed by having a long and triangular anal fin in females. Similar to A. bellottii and A. melanoorus in having the urogenital papilla completely attached to the anal fin in males; differs from A. bellottii in having the dorsal fin more anteriorly placed in males, a shorter anal-fin base, lesser body depth and wider basihyal; differs from A. melanoorus by the number of rostral neuromasts, degree of pelvic-fin fusion, morphology of dorsum in females, color pattern of unpaired fins in males and color pattern of flank in both sexes (Ref. 56780).
属于一个也包括的进化枝 Austrolebias viarius, A. arachan, A. adloffi, A. charrua, A. minuano, A. nigrofasciatus, A. vandenbergi, A. bellottii 与 A. melanoorus,在雌性中是藉由有一个鉴定长而三角形的臀鳍。 类似 A. bellottii，而且 A. melanoorus 有在雄性中是依附於完全的臀鰭的泌尿生殖器的乳突; 有別於 A. bellottii 有放在更前面之內的雄性的背鰭，較短的臀鰭基底，較少的體高與較寬的基舌骨; 有別於 A. melanoorus 藉由嘴神經瘤的數字，腹鰭融合物的程度, 在雌性中的背面的形態學, 雄性與雌性都有的在雄性與側面的彩色斑紋中的不成對鰭的彩色斑紋.(參考文獻 56780)
