polymorphoides sp. n.
Heterolocha polymorpha West
sensu Holloway, 1976: 76.
15-16mm. The facies of this species is very similar to that of H.
polymorpha West (Luzon) and H. falconaria Walker (Himalaya) in the
sinuous shape of the forewing postmedial, and particularly of the latter in the
subcostal displacement distad of a section of the hindwing postmedial. It lacks
the dark spots on the anterior of the forewing postmedial seen in many specimens
of falconaria. It is distinguished best on features of the male
genitalia. The aedeagus has a rod-like cornutus with a spined apex not seen in
the other two species. The furca arms in polymorpha are longer and very
slender. The globular part of the coremata is somewhat turned round on itself in
falconaria, simply round in polymorpha, narrower with a slight
secondary lobe ventrally in polymorphoides. H. polymorpha has genitalia
characteristics similar to those of the Chinese H. aristonaria Walker.
