Scaphobaeocera werneri sp. n. Figs 47-51

HOLOTYPE: Ƌ, E. slope Mt. McKinley, Davao Prov., MINDANAO Elev. 3200ft. Lot #54. IX, 7-8. 1946; beating / CNHM Philippine Zool. Exped. (1946-47) F. G. Werner leg. ( FMNH).

PARATYPES: 3 Ƌ and 2 ♀, with the same data as the holotype ( FMNH, MHNG) .

DESCRIPTION: Length 1. 0-1.10 mm, width 0.55-0.62 mm, dorsoventral diameter 0.58-0.64 mm. Head and most of body uniformly very dark reddish-brown, apex of abdomen and appendages light, ochraceous. Pronotum lacking microsculpture, elytra microsculptured and distinctly iridescent. Punctation extremely fine on pronotum, hypomera, elytra and lateral parts of metaventrite. Length ratio of antennomeres (Fig. 47) as: III 5: IV 6: V 8: VI 7: VII 10: VIII 7: IX 11: X 10: XI 15. Segment III comparatively short, about 3 times as long as wide. Segments IV to VI narrow, as wide as segment III. Segment VII about 2.5 times as long as wide. Segment VIII wider than segment VI. Segments IX and X distinctly larger than segment VII. Segment XI not widened apically, about 3 times as long as wide. Tip of scutellum exposed. Elytra with distinct parasutural striae, sutural striae starting at margin of pronotal lobe, hardly curved at base. Hypomeron not microsculptured, lacking longitudinal stria. Middle part of metaventrite flat, with or without minute, shallow impression, very densely punctate, with short pubescence. Lateral parts of metaventrite sparsely punctate, with striate microsculpture hardly visible at 100x magnification, and fairly long pubescence. Mesocoxal lines with fine marginal punctures fine, not extending laterally along mesepimera; submesocoxal areas about 0.01 mm long. Metepisterna flat, exposed portion about 0.01-0.02 mm wide, almost parallel-sided, with suture slightly curved. Abdomen with distinct striate microsculpture. Abdominal ventrite 1 with basal punctures fairly fine, partly elongate. Tibiae straight.

Male characters. Protarsi with segments 1 to 3 strongly widened, about as wide as protibiae. Aedeagus (Figs 48-51) 0.29-0.32 mm long.

HABITAT: Found by beating vegetation.

DISTRIBUTION: Philippines: Mindanao.

COMMENTS: The aedeagal characters suggest relationship with S. hamata , the shape of the base of the flagellum in these species is, however, clearly distinctive. This species may be distinguished from S. hamata also by its narrow metepisterna.

ETYMOLOGY: The species is named in honour of its collector, Floyd G. Werner.
