Clade A4: Austrolebias bellottii View in CoL View at ENA species group

Diagnosis

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).
