Panacra Walker

Type species: automedon Walker.

Species in this genus resemble those of the Theretra and Hippotion group in forewing facies, but have the margin of the forewing more or less angled, the hindwing margins crenulate, and irregular, more sinuous forewing fasciation, particularly in the apical zone where the fasciae become zig-zag, often with white elements.

In the male genitalia the uncus, gnathus and valve are structured much as in the Theretra group and other typical macroglossines. The aedeagus has an apical process with, usually, two arms flexed back and apically spined as in some preceding genera and many of the Theretra group. These structures have been illustrated for numerous macroglossines by Rothschild & Jordan (1903) and for several Panacra by Dupont & Roepke (1941).

The larva is tapered anteriorly, swollen from T3 over A1, with a pair of dorsolateral ocellar markings on the latter segment. The majority of host-plant records are from the family Araceae. The genus is predominantly Oriental but extends into the Papuan Subregion (D'Abrera, 1986: 134).
