Diagnosis. This is the largest Bornean species, with a distinctive quadrate mark on
the dorsum and a large marginal red patch on the forewing underside.
Taxonomic notes. The taxa listed in the synonymy are distinct from specularia Moore,
the Indian species with which pryeri, vitrigera and prattorum, have
been placed as subspecies. All have a similar quadrate (cf. more broken and
oblique) mark on the forewing dorsum and share a distinctive very long, slender,
Y-shaped process from the aedeagus. Males of specularia have narrow
wings, lack an aedeagus process and have a distinctive basal spur in the centre
of the valve.
Geographical range. Japan, Taiwan, N.E. Himalaya, Sumatra, Borneo, New
Guinea, ?Queensland.
Habitat preference. Bornean material is restricted to the two females
recorded from G. Kinabalu by Holloway (1976), from 1620m and 1930m.
Biology. The larva in Japan is illustrated in Sugi (1987). It is slender, bright
green, with a blackish central stripe to the head and further blackish markings
just above the line of the legs and prolegs. Pupation is in foliage in a loose,
rusty orange cocoon of silk.
The host-plants given by Sugi were Lindera,
Neolitsea and Machilus (Lauraceae). Sato & Nakajima (1975)
recorded Meratia from the same family, and Miyata (1983) added Persea.
