What is "philodila"

Philodila is a genus of moths in the Sphingidae family, containing only one species Philodila astyanor, which is known from the Society Islands.

It is similar to Gnathothlibus species, but distinguishable by the lack of any yellow or orange on the hindwing upperside. The antennae are very long, extending beyond the discal spot. The forewing apex is produced and the outer margin is obtusely angulate. The forewing upperside ground colour is brown. The antemedian band is slightly and evenly curved, the edges darker brown, medially with a slight purplish tone and situated just basal of the small dark discal spot. The apex has a brown triangular mark. The marginal band has an irregular proximal edge. The hindwing upperside is reddish-brown with a greyish marginal band.
