Thalera flavifusata Walker,
1861, List Specimens lepid. Insects Colln Br. Mus. 22: 596.
Thalassodes sinuata Moore,
1867, Proc. zool. Soc. Lond., 1867: 637.
Diagnosis. The white costa and dark dentate fasciae are diagnostic. Albinospila
floresaria Walker is similar in appearance but with white fasciae.
The next two species are distinguished by a dark triangle where the hindwing
postmedial meets the dorsum: some of the Australasian taxa also have this
notes. This species would not appear
to occur east of Sundaland. Taxa attributed to it from Sulawesi and the
Australasian tropics have distinct male genitalia and should be regarded as good
species: O. flavilinea Warren stat. rev. (Queensland); O.
rufinotata Warren stat. rev. (New Guinea, Sulawesi); O. stellata Warren
stat. rev. (=
islands S.E. of New Guinea to Solomons); O. moniliata Warren stat. rev. (Solomons).
Geographical range. Oriental tropics to Sundaland.
Habitat preference. The species is infrequent in lowland forest, including heath
forest, and also softwood plantations (Chey, 1994).
Biology. The larva has been described by Moore (1847) and Bell (MS),
illustrated by the former. It is yellow, with a dorsal, slender, red double
line, the middle segments with narrow black loops on either side of the double
line. The build is slender, the head apically bifid. Bell referred to the dark
dorsal and subdorsal markings as being on slight ridges.
The larva feeds on young
foliage. Pupation is in a cell between two leaves spun together and perforated.
Host-plants recorded by
these authors, Browne (1968), Kuroko & Lewvanich (1993), Zhang (1994) and in
unpublished IIE records are: Anacardium (Anacardiaceae); Barringtonia (Lecythidaceae);
Memecylon (Melastomataceae); Eugenia, Syzygium (Myrtaceae); Nephelium
(Sapindaceae); Chrysophyllum (Sapotaceae).
