Olene dudgeoni Swinhoe comb. n.
Dasychira dudgeoni Swinhoe, 1907, Ann. Mag. nat.
Hist. (7), 19: 203.
Pseudodura dasychiroides Strand 1914, Ent. Mitt., 3: 333.
Dasychira dudgeoni Swinhoe; Holloway, 1976: 51.
Diagnosis. This species resembles mendosa to some extent but the forewings
are a darker, more leaden grey, with the transverse, black antemedial in a more
basal position, without a pale blotch basal to it. No females have been seen:
they may be flightless with vestigial wings.
Taxonomic note. This species is best combined with Olene, the forewing facies
having similarities with that of mendosa. However, the male genitalia
have a narrower, more triangular uncus and strong saccus; the valves lack a
dorsal arm. Pseudodura Strand is best retained at subgeneric level.
Geographical range. N.E. Himalaya to Taiwan and Sundaland.
Habitat preference. The species is infrequent, perhaps slightly commoner
in montane habitats, but recorded from 300m to 1680m in recent surveys.
