Sauris usta Warren

Sauris usta poeciloteucta Prout, 1932: 77, stat. rev.

Sauris usta asema Prout, 1958, Bull. Br. Mus. nat. Hist. (Ent.) 6: 461.

Sauris poeciloteucta Prout; Holloway, 1976: 73.

Sauris marginepunctata Prout sensu Holloway, 1976: 77.

Diagnosis

The forewings are traversed by an even array of numerous dull green fasciae. These fasciae are darkened more markedly medially and, in a more broken fashion, submarginally. The male forewing margin is not cleft subtornally.

The hindwings are grey, those of the male lobed, the central lobe and groove basal to it a darker grey.

Taxonomic Notes

1. The male genitalia of usta and poeciloteucta are identical, therefore the original status of the latter is revived.
2. The specimens attributed to S. marginepunctata Prout by Holloway (1976) are probably merely lightly marked females of usta. In marginepunctata the hindwings are bone-white rather than grey.
3. Sauris usta ab. stictifascia Prout A strongly marked female of this form of the variable S. usta Prout was taken on the slopes of G. Kinabalu (Colln Herbulot). The forewing fasciation is more grey-green than in typical specimens, with a strongly blackhead medial band. The male genitalia are as in usta.
