Hostplant. Nauclea orientalis (Linn.) (Rubiaceae) ( Robinson, Tuck & Shaffer, 1994).

Distribution. Brunei, Indonesia.

Diagnosis. This species resembles externally S. rotundivalvula Li ( Fig. 20), but can be separated from it by the forewing having the largest spot at 3/5 wing length; in the male genitalia by the valva with small processes throughout and the wider valvella ( Fig. 43); and the regularly cone-shaped sterigma in the female genitalia ( Fig. 56). In S. rotundivalvula Li , the forewing has the largest spot at end of cell, the valva has small processes partially and the valvella is narrower ( Fig. 44); and the sterigma is trapezoid ( Fig. 57).

Notes. The female of this species is described for the first time.
