HOLOTYPE: Ƌ, Luzon , Lagunas Prov., Mt. Makiling, 600m, summit rd,

21.XI.1995, leg. I. Löbl ( MHNG) .

PARATYPES: 1 ♀, with the same data as the holotype ; 1 ♀, Luzon , Lagunas , Mt. Banahaw nr school about 1 km from Kinabuhayan, 500m, 26.XI.1995, leg. J. Kodada (both MHNG) .

DESCRIPTION: Length 1.15-1.25 mm, width 0.70 mm, dorsoventral diameter 0.63-0.70 mm. Head and body uniformly reddish-brown, femora lighter, apical abdominal segments, tibiae, tarsi and antennae light brown or yellowish. Pronotum lacking microsculpture. Elytra, hypomera, lateral parts of metaventrite, mesepisterna, mesepimera and abdomen with distinct microsculpture. Elytra iridescent. Pronotal and elytral punctation very fine, barely visible at magnification 50x. Length ratio of antennomeres as: III 4: IV 6: V 8: VI 8: VII 13: VIII 7: IX 12: X 12: XI 15. Segment III short, about twice as long as wide. Segments IV to VI narrow, as wide as segment III, segment IV about 3 times as long as wide, segments V and VI each about 4 times as long as wide. Segment VII about 3 times as long as wide. Segment VIII about twice as long as wide. Segments IX to XI each slightly wider than segment VII, XI 3 times as long as wide. Scutellum entirely concealed. Elytra with parasutural striae, sutural striae starting at margin of pronotal lobe, hardly curved at base. Hypomeron lacking longitu- dinal stria. Middle part of metaventrite flat, with median stria, distinctly, densely punctate, with short pubescence. Sides of metaventrite with fairly dense, fine punctation and fairly long pubescence. Mesocoxal lines with fine marginal punctures not extending laterally along mesepimera; submesocoxal areas about 0.02 mm long. Metepisterna flat, exposed portion about 0.03-0.04 mm wide, parallel-sided, with straight suture. Abdominal microsculpture distinct, ventrite 1 iridescent. Basal punctures of ventrite 1 not elongate. Tibiae straight in female.

Male characters. Protarsi with segments 1 to 3 distinctly widened, narrowed than protibiae. Protibiae straight, mesotibiae slightly curved, metatibiae somewhat sinuate. Aedeagus (Figs 37, 38) 0.42 mm long.

HABITAT: Degraded evergreen rain forest, leaf litter.

DISTRIBUTION: Philippines: Luzon.

COMMENTS: This species shares most of the aedeagal characters with S. tenella Löbl, 1990 . However, it differs from the latter species by the shape of the parameral apices which are clearly distinctive in lateral view. See also comments under B. davaoana .
