Rhodafra opheltes
Superficially similar to Hyles but immediately distinguishable by the characteristic crest on the second segment of the labial palps and the single pair of subdorsal black spots on abdominal segment 2. Antennae less clubbed than in Hyles.Abdominal tergites with weak spines along the posterior margins (as in Deilephila).Abdomen segment 2 with a single large pair of black subdorsal patches . Scaling of labial palp segment 2 characteristic: the scales medially are short, becoming progressively longer laterally to form a crest that appears as the continuation of the eye-lashes. Forewing upperside similar to Hyles euphorbiarum but inner edge of the olive-green triangular postmedian band uniformly concave (not convex between CuA1 and the inner margin). Hindwing upperside similar to Hyles euphorbiae euphorbiae but black basal area less extensive along the costa. Hindwing underside anal area black basally. Valve with numerous small stridulatory scales.Harpe similar to Deilephila, broad, rounded apically, hollowed dorsally.Aedeagus with apical edge thickened and dentate, ending on both sides in a short process.
