Ariolica
Walker
Type
species: lineolata
Walker, Borneo.
Synonym: Chionomera
Butler (type species
superba
Moore, India).
All species have pure white hindwings and most have the forewings transversely
banded with areas of green (or yellow) and white, the coloured areas being edged
or otherwise marked with brown; the exception is A.
nephodes
Prout (Peninsular Malaysia, Sumatra) with orange- or grey-clouded yellow
forewings. The forewing venation lacks an areole, and the radial sector
branching is reduced to (R2 (R3, R4)). In the hindwing, Rs and M1 are stalked,
and sometimes also M3 and CuA1.
The male abdomen has distinctive tymbal structures on the basal sternite: a pair
of squarish plates with their adjacent margins united by a pocket-like structure
(Fig. 361). The eighth tergite has narrow apodemes. The genitalia are rather
diverse in structure but share a hair pencil at the base of the valve
exteriorly.
The female genitalia have the ductus or the base of the bursa with a zone of
unsclerotised thickening. The main part of the bursa is narrow but with an
extensive zone (or zones) of coarse spining.
The genus is restricted to the Oriental mainland apart from the only Bornean
species and nephodes.
The Japanese species,
A.
argentea
Butler, has a rather spindle-shaped slightly translucent green larva that feeds
on Rhododendron (Ericaceae) (Sugi, 1987).
