Diagnosis.
The wings are a dark, dull brown, with punctate blackish fasciation and reniform
marks on the forewing. The hindwing medial and forewing “postmedial”, when
not obscure, are straight, that of the forewing oblique, angling subcostally as
well as continuing straight on, the two components enclosing a lens of brownish
blue to blue scales at the costa. The actual postmedial of the forewing (the
inner component) is more punctate and irregular but can be obscured by the
development of the straight, oblique line (the outer component).
Taxonomic
note. Particular features of the male genitalia are discussed under
the next species. The eighth segment is intermediate between that of typical Sarobides
and
Saroba.
The valve processes are relatively basal, the apical part long and slender. The
aedeagus is short, broad, the vesica convolute, with cornuti and scobination.
The females of both species have a moderately complex sterigma and a short,
broad ductus; the corpus bursae is relatively small, with an irregular,
incomplete ring of small spines subbasally.
Geographical
range. Indian Subregion, Andamans, Singapore, Sumatra, Borneo.
Habitat
preference. Only three specimens are known, all taken during the Mulu
survey: in dipterocarp forest at 150m on G. Mulu; in lower montane forest at
900m and in montane scrub at 1500m on the limestone G. Api.
