Mariaba Walker
Genus Details
Type species: convoluta Walker.
Synonym: Adeta Warren (type species semifascia Warren, New Guinea).
A close relative of Onagrodes, Mariaba has male sexual modifications that distinguish it: very much more deepened forewings (expanded at the dorsum); rather reduced, square or triangular hindwings that are plain dorsally yet fasciated on the underside (strongly so in semifascia). The main expansion of the hindwings is in the anal area posterior to the cell, and the more or less uniformly coloured scales on the upperside are presumably androconial.
The male genitalia have the saccus enlarged, squarish, and the sacculus is distinctly angular.
The genus consists of the type species and M. semifascia Warren (New Guinea, Solomons, Sulawesi).
