Diagnosis. The facies is atypical, the wings a uniform pale grey with finely
punctate dark postmedials. The hindwing has an acute tail at M3, and the
forewing is apically truncate, a submarginal spot and stronger marginal
punctation associated with the posterior angle of the truncation.
Taxonomic notes. Structures of tegumen, valve and aedeagus in the male genitalia show
this species to be a typical Hypomecis. In the female the bursa and
signum are comparable but the ovipositor is elongate and telescopic as in Ectropis
and Cleora. The genitalia of New Guinea males are similar to those of
typical Oriental males, hence pallidiplaga Warren is brought into
synonymy, but possibly should have subspecific status in consideration of the
more speckled appearance of material from the east of the range of the species.
Material from Sulawesi is larger than that from elsewhere.
Geographical range. N.E. Himalaya, Peninsular Malaysia, Sumatra, Borneo,
Sulawesi, S. Moluccas, New Guinea (Sud-Est. I.).
Habitat preference. Most records are from lowland forest, particularly
kerangas during the Mulu survey, but a few individuals have been taken in lower
