Pronotal and elytral punctation very fine, distinct at magnification 50x. Length ratio of antennomeres as: III 6: IV 8: V 9: VI 8: VII 10: VIII 8: IX 10: X 10: XI 12. Segment III about 3 times as long as wide. Segment 4 about as narrow as segment III, segments V and VI slightly wider, each about 3 times as long as wide. Segment VII 3 times as long as wide. Segment VIII slightly wider than segment VI, about 3 times as long as wide. Segments IX to XI distinctly wider than segment VII, segment XI about 2.5 times as long as wide. Scutellum entirely concealed. Elytra with parasutural striae obsolete, sutural striae starting at margin of pronotal lobe, slightly curved at base. Hypomeron without stria. Middle part of metaventrite flattened, with very shallow, minute impression in middle, dense and fairly fine punctation except on anterior area, and fairly long pubescence. Sides of metaventrite sparsely and very finely punctate, with long pubescence. Mesocoxal lines with fine marginal punctures, not extending laterally along mesepimera; submesocoxal areas about 0.03 mm long. Metepisterna somewhat convex, with exposed portion about 0.06 mm wide, parallel-sided, suture deep and straight. Abdominal ventrite 1 very finely punctate, with basal punctures fairly coarse and elongate.

Male characters. Protarsi with segments 1 to 3 moderately widened, narrower than protibiae. Aedeagus (Figs 31-34) 0.60 mm long.

COMMENTS: This species is similar to S. data in external characters but may be distinguished by the elongate punctures at the base of the abdominal ventrite 1. See also comments under S. davaoana .

ETYMOLOGY: The species is named in honour of one of its collectors, Jean

Orousset, Paris.
