FIGS 1-6 (1, 2) Scaphobaeocera bulbosa sp. n. , aedeagus in dorsal and lateral views; scale bar = 0.1 mm . (3-6) Scaphobaeocera complicans sp. n. , aedeagus (3, 4) and internal sac (5, 6) in dorsal and lateral views. Scale bars = 0.2 mm for aedeagus, = 0.1 mm for internal sac. PARATYPES : 7 Ƌ, 13 ♀ , with the same data as the holotype. – 1 Ƌ, Philippines , Mt. Makiling , Lagunas Prov. 4 km SE Los Banos , 12-IV-1977 / berlese rotten logs L. E. Watrous. – 1 Ƌ with the same data but 9-IV-1977 and berlese rotten figs (all MHNG ) . DESCRIPTION: Length 1.05-1.20 mm , width 0.57-0.68 mm , dorsoventral diameter 0.65-0.75 mm . Body rufous, apical abdominal segments and appendages light ochraceus to yellowish. Thorax, elytra and abdominal ventrite 1 not microsculptured and not iridescent. Pronotal and elytral punctation very fine, that on elytra slightly coarser than on pronotum. Length ratio of antennomeres as: III 4: IV 8: V 9: VI 7: VII 10: VIII 6: IX 9: X 10: XI 26. Segment III short and narrow, about twice long as wide. Segments IV as narrow as segment III. Segments V and VI slightly wider than segment IV, segment V about 3 to 4 times as long as wide. Segment VII about 2.5 times as long as wide. Segment VIII twice as long as large. Segments IX and X slightly wider than segment VII. Segment XI conspicuously long, about 5 times as long as wide. Tip of scutellum exposed. Elytra with very fine parasutural striae, sutural striae starting at margin of pronotal lobe, slightly curved at base. Hypomeron with stria. Middle part of metaventrite hardly convex, lacking stria or impression, with dense and fairly fine punctation except on narrow anterior area, and with fairly long pubescence. Sides of metaventrite sparsely and finely punctate, with long pubescence. Mesocoxal lines with fine marginal punctures, not extending laterally along mesepimera; submesocoxal areas about 0.03 mm long. Metepisterna flat, with exposed portion about 0.06-0.08 mm wide, parallel-sided, with straight suture. Abdominal ventrite 1 very finely punctate, with basal punctures fine, partly somewhat elongate. Following sternites with punctulate microsculpture. Tibiae straight. Male characters. Protarsi with segments 1 to 3 moderately widened, narrower than protibiae. Aedeagus (Figs 3-6) 0.44-0.53 mm long. HABITAT: Evergreen rain forest, fungi on large log, in rotten log and on rotten figs. DISTRIBUTION: Philippines : Luzon. COMMENTS: Several members of Scaphobaeocera have conspicuously long apical antennomere, compared to the antennomeres VII and X ( S. abnormalis Löbl, 1981 , S. antennalis Löbl, 1975, S. cyrta Löbl, 1980, S. delicatula Löbl, 1971, S. dispar Löbl, 1980, S. dorsalis Löbl, 1980, S. japonica (Reitter, 1880), S. minutissima ( Löbl, 1969 ), S. ponapensis Löbl, 1981, S. remota Löbl, 1981, and S. stephensoni Löbl, 1988). Scaphobaeocera complicans may be easily distinguished from those species by the shape of the internal sac of the aedeagus, in particular by its strongly expanded apical part and the bulbous basal part.
