DESCRIPTION: Length 0.92-0.96 mm, width 0.60-0.68 mm. Body convex dorsally, dark brown, apices of elytra slightly lighter, femora and tibiae reddish-brown, tarsi and antennae almost yellowish. Eyes large. Length ratio of antennomeres as: III 8: VI 7: V 7: VI 6: VII 8: VIII 7: IX 10: X 10: XI 11. Antennomeres III to VI evenly

FIGS 10-18

(10-13) Baeocera profana sp. n., aedeagus (10, 11) in dorsal and lateral views, paramere (12, 13) in dorsal and lateral views; scale bar = 0.1 mm for aedeagus, = 0.05 mm for paramere. (14-16) Baeocera simoni (Pic) , paramere (14) in dorsal view, aedeagus (15, 16) in dorsal and lateral views; scale bar = 0.1 mm for aedeagus, = 0.05 for paramere. (17-18) Baeocera boettcheri (Löbl) , internal sac (17) and paramere (18) in dorsal view; scale bars = 0.05 mm.

narrow; VII about 3 times as long as wide, much wider than VI; VIII distinctly wider than VI, about 2.5 times as long as wide; IX to XI each distinctly wider than VII, XI about 2.5 times as long as wide. Pronotum and elytra without microsculpture, with lateral contours almost continuously arcuate; pubescence visible at 50 times magnification. Pronotum extremely finely punctate, with lateral margins strongly convex, lateral margin carinae concealed in dorsal view. Scutellum concealed, or its minute tip visible. Elytra almost covering apex of abdomen, with lateral carinae concealed in dorsal view. Elytron with sutural stria fine, curved along basal margin to form basal stria. Latter very shallow and hardly visible in outer half of basal width. Elytral punctation very fine on most of surface, narrow patch of less fine punctures situated on lateral area, starting somewhat posterior base and extended about to elytral mid-length. Hind wings not reduced. Hypomera impunctate. Mesepimera flat, comparatively large, about 3 times as long as wide and about 4 times as long as interval to mesocoxa. Metaventrite slightly convex in middle, with fairly large impunctate central area, around centre distinctly, rather finely punctate. Lateral parts of metaventrite impunctate near metacoxae, rather finely, irrerularly punctate on remaining surface, punctures becoming somewhat larger toward anterior part of metanepisterna. Submesocoxal lines parallel, with marginal punctures about as large as those around smooth centre of metaventrite, not extended along anapleural suture. Submesocoxal area about 0.02 to 0.03 mm long, shortest interval between its margin and metacoxa about 0.07 mm. Metanepisterna flat, fused to metaventrite, suture indicated by outer row of puncture lying in somewhat impressed stria. Metepimera with slightly carinate inner margin. Abdominal ventrite 1 lacking microsculpture, with basal punctures moderately coarse, not elongate, contiguous in middle, extended to lateral margins; basal rugosity absent. Punctation very fine posterior basal puncture row. Tibiae straight.

Male characters: Tarsomeres 1 to 3 of forelegs hardly widened. Aedeagus as in

Figs 19-22, 0.24-0.27 mm long. Median lobe moderately sclerotized.

DISTRIBUTION: Philippines, Luzon.

ETYMOLOGY: The species is named in honour of my wife Daniela, in acknowledgement to her efficient assistance under difficult field conditions.

COMMENTS: This species may be distinguished from other members of the B. lenta group by its elytral punctation distinct only on a very small lateral surface, in combination with the short antennae, the entire sutural striae of the elytra, and the parameres not widened in middle.

HABITAT: Leaf litter and other forest floor debris in evergreen rainforest and mountain forest, ranging from 400 to about 2300m above sea level.

DISTRIBUTION: Philippines, Luzon.

COMMENTS: The description of this species was based on a female from "Balbalan, Luzon" (MNHN), originally placed in Scaphisoma Leach. Löbl (1971b) transferred it to Eubaeocera Cornell, 1967 (a junior synonym of Baeocera Erichson, 1845 ), and provided its redescription ( Löbl, 1972). The aedeagal characters of B. globosa are illustrated in Figs 23-26.
