Distinguished from remaining taxa of the genus Austrolebias  ZBK  in having anteromedian rays of anal fin long in females, resulting in a nearly triangular fin shape (vs. rays short and fin rounded), four to six contact organs on each flank scale in males (vs. a single contact organ per scale) (reversed in A. melanoorus  ), and anterior arm of ceratobranchial 5 longer than posterior arm (vs. shorter) (homoplastically occurring in A. cinereus  , but not present in all species of clade A5, considered a reversal).
