DESCRIPTION: Length 1.05-1.25 mm, width 0.57-0.70 mm, dorsoventral diameter 0.59-0.72 mm. Head and body very dark, almost blackish, femora rufous, apical abdominal segments and remainder of appendages lighter, ochraceous. Thorax and elytra microsculptured, elytra very weakly iridescent. Pronotal and elytral punctation very fine, distinct at magnification 50x, punctation becoming somewhat coarser toward elytral apices. Length ratio of antennomeres as: III 5: IV 8: V 10: VI 9: VII 10: VIII 9: IX 12: X 12: XI 15. Segments III to VI equally narrow, segment III about twice as long as wide, segment V about 4 times as long as wide. Segments VII to IX each about 3 times as long as wide, segment VIII wider than segment VI. Segment XI almost 3 times as long as wide. Tip of scutellum exposed. Elytra with parasutural striae hardly visible, sutural striae starting at margin of pronotal lobe, slightly curved at base. Hypomeron lacking longitudinal stria, with striate microsculpture. Middle part of metaventrite flat, with small, shallow impression in middle, densely and finely punctate, and short pubescence. Sides of metaventrite sparsely, extremely finely punctate, with long pubescence. Mesocoxal lines with very fine marginal punctures not extending laterally along mesepimera; submesocoxal areas about 0.03-0.05 mm long. Metepisterna flat, exposed portion about 0.06 mm wide, parallel-sided, with straight suture. Abdomen with fairly distinct striate microsculpture, very finely punctate. Basal punctures of ventrite 1 very fine. Tibiae straight.

Male characters. Protarsi with segments 1 to 3 slightly widened, much narrow- er than protibiae. Aedeagus (Figs 1, 2) 0.28-0.31 mm long.

HABITAT: Degraded evergreen rain forest, in leaf litter and samples of moss and epiphytes on logs, under bark.

DISTRIBUTION: Philippines: Luzon.

COMMENTS: This species is in external characters very similar to S. sabapensis Löbl, 1990 . It may be distinguished from the latter by the aedeagus with shorter and thicker apical part of the median lobe, shorter parameres, and distinctive shape of the flagellum.
