Araeopteron vilhelmina. This species was listed in Franclemont and Todd (1983) on the basis of records from Florida. This could be a complex of species, based on slight differences in wing pattern between the material from Florida and Cuba as compared with typical vilhelmina, which occurs in southern Mexico and Central America. The genitalia are very simple structurally, so more material is needed to resolve the identity of the species in southern Florida. The valve is mainly membranous, broad and slightly concave apically and without any processes. None of the New World species of Araeopteroninae examined, including Araeopteron vilhelmina, has the structural characters used to define the Araeopteroninae by Fibiger (2005) and it appears that the Araeopteroninae may be restricted to the Old World. In the Araeopteroninae the male valve is deeply cleft with the lower half of the valve heavily sclerotized and apically clubbed; in the female corpus bursae there is a heavily sclerotized plate covered with long spines. A. vilhemina is structurally close to the genus Sigela Hulst except that M2 extends to the lower margin of the cell, so the forewing is quadrifine and not trifine as in Sigela.
