Lophoptera
longipennis Moore comb. n.
Sadarsa longipennis Moore,
1882, Descr. new Indian Lepid. Colln. Atkinson, p. 165.
Diagnosis. The
female is much as in L. tenuis except for the less hyaline hindwing and
almost vestigial post-ostial invagination mentioned above. The extremely
produced forewings of the male render it unmistakable.
Taxonomic note. The
equal development of appendix bursae and bursa copulatrix and indications of a
vestigial post-ostial invagination in the female genitalia, as well as facies
similarities with L. tenuis, indicate that this is a somewhat divergent Lophoptera
and therefore the genus Sadarsa Moore should be placed in synonymy
with that genus, syn. n. The genitalia of both sexes are somewhat different from
those of tenuis so the species is placed in a distinct subgroup.
Females of longipennis
from outside Borneo are much less similar to tenuis, having faint
pale brown patches and fasciae.
Geographical
range. N.E.
Himalaya, Taiwan, Sumatra, Java, Borneo.
Habitat
preference. The
species is montane in Sundaland, being recorded from localities at around 1500m
on G. Kinabalu in Borneo.
