Epiplema clathrata Warren,
1896, Novit. zool., 3: 347.
Diagnosis. This is a small brown species with facies similar to Pterotosoma and
Oroplema, but characterised by a broad blackish lining, broken along the
veins, basal to the paler postmedial on each wing, and more weakly distal to the
antemedial. The distal margin of the forewing has a slight protrusion at CuA1.
There is a longitudinal dark brown streak on the hindwing running from the base
to just short of the angle in the postmedial.
Taxonomic notes. M2 in the hindwing is lacking. The male genitalia are somewhat similar
to those of the genera mentioned in the diagnosis, but the uncus is broader
basally, there is a weak gnathus, and the valves have a looped fold
submarginally. At the base of each valve there is a complex pocket with a strong
hair-pencil. The juxta is a large rhomboidal plate. The aedeagus vesica has a
single slender cornutus.
Geographical range. N.E. Himalaya, Borneo, Peninsular Malaysia (FRIM
colln), Java, Bali.
Habitat preference. The only Bornean specimen was taken in a Gmelina
arborea plantation near Brumas in the lowlands of Sabah by Dr Chey Vun Khen.
