Menapia Walker, 1865   ( Menapia xanthophila Walker, 1865   [= Bireta longivitta Walker, 1856   ])

The genus Bireta   includes over 30 species, many of which were previously erroneously attributed to the genus Torigea Matsumura 1934   , that are distributed in Southeast Asia and are best distinguished by male genitalia. Forewings are predominantly yellow, sometimes with an orange brown tint, and contain a small median spot. The basal line extending from the apex to the base of the forewings is brown or silver. Bireta   male antennae are long and bipectinate whereas female antennae are simple and filiform. The male genitalia possesses a short and undivided uncus with a pair of large socii. Sternite VIII is highly modified and the tegumen is massive and robust compared to relatively small valves. The female genitalia have a characteristic round signum.
