Diagnosis.
The species has similar coloration to congeners, but is distinguished by a much
stronger angle to the hindwing margin at CuA2. There are straight, dark brown
medial fasciae on fore- and hindwings, with reticulated pale orange basal to
this and in a subcostal patch distal to it on the former, and in a small central
patch distal to it on the latter.
Taxonomic
note. The male eighth segment has both sclerites very shallow, the
margin of the sternite biarcuate, with a slightly corematous and setose
membranous zone posterior to it. The valves are broad, with a prominent spine
arising centrally from an irregularly transverse ridge. The apical part of the
valve is broad throughout and does not articulate at the junction with the
processes. The juxta is broad, scobinate, with a prominent central peak
dorsally. The aedeagus vesica is small. Phragma lobes are absent from the
anterior of the second abdominal tergite. The species may therefore be misplaced
in the Saroba group. S. cinnaberrina Snellen
(Sumatra) appears from the illustration in the original description and a colour
image of the holotype in RMNH, Leiden, to be antecedens.
Geographical
range. Borneo, Sumatra, Thailand (VK), N.E. Himalaya.
Habitat
preference. The holotype was taken by A.R. Wallace in Sarawak. Two further
specimens have been recorded in recent surveys, one from 60m in lowland forest
of the Ulu Belait in Brunei and one from lowland forest in the Barito Ulu of
Kalimantan Tengah.
