Hypulia convoluta sp. n

Hypulia convoluta

18mm, 15mm. The wings of the male show distinct modifications of shape: the forewing is produced apically somewhat, and the dorsum is convex; the hindwing is produced tornally, with a slight angle at the margin in the position of vein CuA1. The female is similar to that of H. eleuthera, as is the fasciation of both sexes. The genitalia are distinctive. The male has a massively convolute corema on each valve, the uncus is asymmetric, the pseudouncus angled. The valve costa has a central, rather obtuse angle. The aedeagus is extremelly irregular in shape. In the female the ductus and corrugate basal zone of the bursa are relatively short and broad, the bursa elongate rather than spherical, and highly scobinate throughout.
