Ectropidia illepidaria Walker comb. n.stat. rev.

Acidalia illepidaria Walker, 1861, List Specimens lepid. Insects Colln. Br.Mus., 23: 765.

Myrioblephara pustulata Warren, 1900, Novit. zool., 7 :114 syn. n.

Diagnosis

This and the next species are indistinguishable on exterior characters. The facies is variable, not unlike that of E. exprimata and allies but the brown colour is duller, the forewing lacks a marginal patch, and there is often an oblique dark brown suffusion on the forewing like that in Satoblephara hollowayi Sato. The diagnosis of the next species gives the genitalia differences.

Taxonomic notes

The holotype of illepidaria (UM, Oxford) is female, but males matching it exactly in facies, particularly the broader oblique brown suffusion of the forewing, have genitalia as in the holotype of pustulata. The female genitalia have the bursa more elongate, the basal narrow section longer and less scobinate than in the next species, reflecting the less heavy scobination of the male aedeagus vesica. The holotype of E. coremaria Hampson (Sri Lanka) has similar genitalic features but it is a larger insect with the wings a more uniform dark brown. The abdominal coremata are more as in the next species.

Geographical range

Borneo, Sumatra.

Habitat preference

Both species are frequent in forests from the lowlands to the lower montane zone at about 1000m, but no specimens of illepidariahave been identified from upper montane forest.
