Thalera celataria Walker, 1866, List Specimens lepid. Insects
Colln. Br. Mus., 35: 1614.
Euchloris thalassica Turner,
1904, Trans Roy. Soc. S. Australia, 28: 221.
Diagnosis. The fasciation is white, the postmedials
partly sinuous. There is a grey submarginal band on the underside that
intensifies on both wings towards their junction at the forewing dorsum and the
hindwing costa. The saccular process has a strong subbasal flexure, and is
apically upturned. The pouch between the valve bases is broad, rounded.
Taxonomic notes. The male genitalia indicate a close
relationship with 1. caudularia Guenée (Sri Lanka, S. India), I.
contracta Warren (Himalaya) and I. androcmes Prout (Bali). In these
other taxa the pale fasciae are generally straighter. I. subtusumbrata Fuchs
is probably also related or synonymous. The group requires further study.
Geographical range. Sulawesi, Borneo, (?Sumatra, Peninsular
Malaysia - subtusumbrata), Seram, Kei, New Guinea; Queensland (ssp. thalassica).
preference. The male identified from
genitalic characters (slide 17396) is from G. Kinabalu (Waterstradt) with no
altitude given. Other material is from lowland localities.
Biology. Yunus & Ho (1980) recorded a species identified as subtusumbrata
from Coffea (Rubiaceae). The identity needs to be confirmed by
dissection of the specimens concerned.
