Idolopsalinae Steinmann 1975

Idolopsalinae Steinmann, 1975 Updated diagnosis (adapted from Brindle 1971, Steinmann 1989 and Srivastava 1999): Body of typical form, not strongly flattened dorso-ventrally. Head typical (about as broad as long, tumid, lateral margins curving smoothly into posterior margin, the latter almost straight, slightly concave medially), eyes moderately large, but more or less shorter than length of head behind eyes. First antennal segment relatively short, shorter than the distance between antennal bases. Tegmina and wings totally absent. Mesosternum and metasternum with hind margin truncate (even if the hind margin of the mesosternum is broadly rounded, it remains transverse overall and does not form a semicircular (or tongue-shaped) posterior portion, as seen in the Anisolabidinae, Anophthalmolabidinae, and Titanolabidinae). Basal piece of male genitalia deeply incised posteriorly. Ultimate tergite not setose, lateral sides almost parallel. Neotropical distribution.
