Dindica Moore

Type species basiflavata Moore = polyphaenaria Guenée.

Synonym: Perissolophia Warren (type species subrosea Warren, Sikkim).

This genus has been recently revised by Inoue (1990), who discovered a situation of much greater complexity in S.E. Asia than was suggested by the preliminary investigation of Holloway (1982).

The facies of most species is as in the three Bornean species illustrated here: greenish forewing and yellow hindwings with a brownish or blackish border. In some mainland Asian species the green and yellow tints are reduced or absent. On the underside the pattern is typical of the Pseudoterpniti, often with the ground colour extremely yellow. The male antennae are narrowly bipectinate over most of their length, the termination of the pectinations varying from species to species.

In the male abdomen there is a pair of setal patches on the third sternite. The uncal structure of the genitalia is as in Pingasa: partially fused socii giving the impression of a bifid uncus. The valves bear coremata and consist of a sclerotised, variably spined or divided saccular portion that broadly overlaps the costal portion and the main lamella: the apex of the costa is variably produced into a spur, a group of spines or more of a lobe.

The female genitalia have ovipositor lobes of the modified geometrine type. The bursa is immaculate, the ductus short, narrow. The lamellae vaginales form a shallow pouch within which there is a complexity of folds, corrugation and scobination.

The larva (Sugi, 1987, and see D. polyphaenaria below) is robust, leaf green, marked with a fine, white lateral line and sometimes a yellow subdorsal one. The head can also bear a yellow line. The resting posture is stick-like with head and true legs held tightly together.

The recorded larval host-plants have been restricted to the Lauraceae, e.g. Litsea for D. polyphaenaria below and for D. virescens Butler on Benzoin, Parabenzoin and Lindera in Japan (Nakajima & Sato, 1979; Sugi, 1987).

The genus is restricted to the Oriental tropics and subtropics, with its greatest diversity in China (Inoue, 1990).
