usta Warren
Holorista usta Warren, 1904, Novit. zool., 11:106.
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. The male genitalia of usta and poeciloteucta are
identical, therefore the original status of the latter is revived. 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.
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.
Geographical range. Peninsular Malaysia; Borneo (ssp. poeciloteucta); Java
(ssp. asema Prout)
Habitat preference. The species is infrequent in upper montane forest and
ranges from 1000m to 2600m.
