Synegia obscura

This species and the two following can readily be confused, and reference to the male genitalia is advisable. In this species the fasciae are most clearly defined, particularly the biarcuate forewing antemedial; the fasciae are weakest in S. imitaria Walker. The antemedial is somewhat more oblique in varians, meeting the costa at a more acute angle basad. In obscura there is usually an irregular ring of orange-grey on the hindwing submarginally between M1 and M3 (in the ‘ocellate’ species discussed later the ocellus is between M3 and CuA1) The male antennae are perhaps more narrowly bipectinate in obscura and camptogrammaria compared with imitaria. In imitaria the orange speckling and blotches between the fasciae tend to be stronger, coarser, more orange rather than grey; the forewings of the male are narrower than in the other two species. In the male genitalia S. camptogrammaria can be distinguished from obscura by the presence of a row of peg-like setae on the valve and two strong, short cornuti in the aedeagus vesica. S. imitaria has a strong subbasal lobe on the valve costa, a prominent juxta and two long cornuti in the vesica. The saccus is strongly bilobed in obscura and camptogrammaria but hardly at all in imitaria. In the female, all three have an elongate basal section to the bursa but it is fluted only in imitaria. The signum is central in the distal part of the bursa and typical of the genus. The distal part of the bursa is more elongate in camptogrammaria. Other species that would be confused with these three are asymbates Prout and some morphs of potenza Holloway. (See Synegia potenza Holloway)

Taxonomic notes. The species was placed in synonymy with camptogrammaria. It was identified as S. varians Warren by Holloway (1976), a species described from two females from Peninsular Malaysia. The facies in varians and obscura is similar but the female genitalia differ: the signum in varians is relatively larger and set more distally in the bursa; the ductus is short, evenly sclerotised in obscura but twice as long, sclerotised more strongly over the distal half in varians.

Geographical range. S. India, Borneo.

Habitat preference. The species is frequent in upper montane forest.
