Remington ( FMNH ) . DESCRIPTION: Length 1. 0-1.10 mm , width 0.60-0.65 mm , dorsoventral diameter 0.63-0.67 mm . Head and most of body uniformly light ochreous, appendages lighter than body. Pronotum lacking microsculpture. Basal half of elytra not microsculptured, apical half of elytra microsculptured, hardly iridescent. Punctation extremely fine on pronotum, elytra, hypomera and lateral parts of metaventrite. Length ratio of antennomeres as: III 5: IV 6: V 8: VI 5: VII 9: VIII 6: IX 10: X 10: XI 22. Segments III to IV equally narrow, segment IV about 2.5 to 3 times as long as wide. Segment V hardly wider than segment IV, about 4 times as long as wide. Segment VI about 2 to 3 times as long as wide, wider than segment V. Segment VII much wider than segment VI, about twice as long as wide. Segment VIII almost as wide as segment VII and not quite 2 times as long as wide. Segments IX to XI almost equally wide, not or slightly wider than segment VII, segment XI about 4 to 5 times as long as wide. Tip of scutellum exposed. Elytra without parasutural striae, sutural striae starting at margin of pronotal lobe, hardly curved at base. Hypomeron not microsculptured, with longitudinal stria. Middle part of metaventrite slighly convex, without impression, smooth in center, very densely punctate laterally and posterior center, with fairly long pubescence. Mesocoxal lines with marginal punctures fine, distinct, not extending laterally along mesepimera; submesocoxal areas about 0.02 mm long. Metepisterna flat, exposed portion about 0.07-0.09 mm wide, narrowed anteriad, with suture straight and deep. Abdomen with distinct striate microsculpture. Abdominal ventrite 1 very finely punctate, with basal punctures fairly coarse, elongate. Tibiae straight. Male characters. Protarsi with segments 1 to 3 strongly widened, about as wide as protibiae. Aedeagus (Figs 44-46) 0.32-0.34 mm long. FIGS 39-46 (39, 40) Scaphobaeocera pubiventris sp. n. , aedeagus in dorsal and lateral views; scale bar = 0.2 mm . (41-43) Scaphobaeocera serpentis sp. n. , aedeagus in dorsal and lateral views, internal sac (42) enlarged. Scale bar = 0.1 mm for figs 41, 43; scale bar = 0.05 mm for fig. 42. (44-46) Scaphobaeocera watrousi sp. n. , aedeagus in dorsal and lateral views, internal sac (45) enlarged. Scale bar = 0.1mm for figs 44, 46; scale bar = 0.05 mm for fig. 45. HABITAT: Evergreen rain forest, rotted wood and leaf litter. DISTRIBUTION: Philippines : Luzon and Leyte . COMMENTS: The aedeagus of this species is similar to that in S. palawana . This new species may be easily distinguished from the latter by the lighter coloration of the body and the presence of hypomeral striae. ETYMOLOGY: The species is named in honour of one of its collectors, Larry E. Watrous, Ballwin, MO, USA .
