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).
