Eumelea
biflavata Warren
Eumelea ludovicata biflavata Warren,
1896, Novit. zool 3: 357.
Eumelea biflavata assamensis Prout,
1921, Gross-Schmett. Erde 12: 30.
Diagnosis. This and the next two species are similar in appearance, particularly in
the two irregular patches of yellow ground colour interior to the postmedials of
both wings in the males. E. biflavata is a somewhat smaller species where
both postmedial and submarginal fasciae are distinct, pink-suffused, if diffuse,
on the upperside: only the submarginal is strong in the other two species. Males
of biflavata differ from those of ludovicata on the underside of
the forewing in having the marginal zone uniform rather than having anterior and
posterior yellow patches separated by reddish suffusion (seen slightly also on
the upperside). The male genitalia have the distal part of the uncus moderate,
apically blunt. The arms of the cross are short, ovate, the socii small. The
scobination of the aedeagus vesica is very fine, in broad zones that are not
distinctly lyre-like.
Geographical range. N.E. Himalaya, S.E. Asia to Sundaland.
Habitat preference. Recent material indicates this to be an infrequent
species in lowland rain forest.
Biology. Yunus & Ho (1980) recorded Macaranga (Euphorbiaceae) as a
host-plant.
