Lophoptera phaeobasis Hampson
1905, Ann. Mag. nat. Hist. (7), 16: 534.
Holloway, 1976: 19.
Diagnosis. This and the next species are distinguished from congeners by the bluish
black basal zone of the forewing contrasting with a paler distal part; there are
dark markings at the forewing apex; the rest of the wing is dull brown with
diffuse darker bands submarginally, a sinuous, fine, double, dark postmedial and
a finely delineated reniform.
Taxonomic note. This and the next species, with the Himalayan L. negretina Hampson,
are allied to L. hemithyris Hampson, a species which, though not recorded
from Borneo, ranges from Sri Lanka to New Caledonia (Holloway 1979;
illustrations) and possibly Fiji (Robinson 1975) where it feeds as a larva on Glochidion
(Euphorbiaceae). The valves of the male genitalia are relatively simple and
the uncus is flanged in this species group.
Geographical range. Peninsular Malaysia, Sumatra, Borneo, ?New Guinea
(specimens with the apical part of the valve broader, the uncus narrower as in
the next species).
Habitat preference. A specimen was taken at 1200m on G. Kinabalu and two
in lower montane forest at 900m on G. Api.
