DESCRIPTION: Length 1. 0-1.20 mm, width 0.65-0.80 mm. Body convex dorsally, dark brown or dark reddish-brown, femora and tibiae lighter, apex of abdomen, tarsi and antennae yellowish. Eyes large. Length ratio of antennomeres as: III 5: IV 6: V 7: VI 7: VII 10: VIII 6: IX 9: X 10: XI 11. Antennomeres III, IV and VI evenly narrow, V slightly wider than IV, about 4 times as long as wide, VI about 5 times as long as wide; VII comparatively narrow, slightly wider than V, about 4 times as long as wide; VIII distinctly narrower than VII, about 3 times as long as wide; IX to XI each distinctly wider than VII, XI about 3 times as long as wide. Pronotum and elytra without microsculpture, with lateral contours separately arcuate; pubescence visible at 50 FIGS 27-34

(27-30) Baeocera hypomeralis sp. n., aedeagus (27, 28) in dorsal and lateral views, paramere (29) and internal sac (30) in dorsal view; scale bar = 0.1 mm for aedeagus, = 0.05 mm for paramere and internal sac. (31-34) Baeocera jankodadai sp. n., aedeagus (31, 32) in dorsal and lateral views, paramere (33) and internal sac (34) in dorsal view; scale bar = 0.1 mm for aedeagus, = 0.05 mm for paramere and internal sac.

times magnification. Pronotum very finely punctate, with lateral margin carinae concealed in dorsal view. Scutellum concealed. Elytra almost covering apex of abdomen, with lateral carinae concealed or shortly exposed near base. Elytron with sutural stria deep, curved at base to form basal stria reaching about basal mid-width, adsutural area flat. Elytral punctation almost evanescent or very fine, similar to pronotal punctation along base, on narrow strip along sutural stria and on entire apical third. Remaining surface of elytral disc with fairly coarse punctures, puncture intervals about 2 to 3 times as large as diameters of coarse punctures. Hind wings not reduced. Hypomera impunctate. Mesepimera flat, about 3 times as long as wide and about 4 times as long as interval to mesocoxa. Metaventrite somewhat convex in middle, with impunctate central surface small, around centre distinctly punctate. Lateral parts of metaventrite impunctate on posterior area; remaining surface with irregular, fairly coarse punctures. Punctures on lateral parts of metaventrite larger than those around centre, usually slightly elongate and larger than, or about as large as puncture intervals. Submesocoxal lines parallel, with marginal punctures about as large as those around 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 0.10 mm. Metanepisterna flat, with suture indistinct, indicated by outer row of coarse punctures. Metepimera with carinate inner margin. Abdominal ventrite 1 lacking microsculpture, with basal punctures fairly coarse, not or barely interrupted in middle, extended almost to lateral margins, elongate laterally, and with 0.02-0.04 mm long wrinkles. Punctation posterior basal puncture row very fine on side of ventrite, distinct on mesal area. Tibiae straight.

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

Figs 31-34, 0.30-0.35 mm long. Median lobe moderately sclerotized.

HABITAT: The specimens were found at low elevation, from sea level to about 300 m above sea level. They come from both, primary forest as strongly degraded secondary forest, and were found in accumulation of rotten leaf samples and on a rotten trunk.

DISTRIBUTION: Philippines, Palawan.

ETYMOLOGY: The species is names in honour of my friend Jan Kodada, Bratislava, Slovakia, who collected most of the specimens of this new species.

COMMENTS: This species is similar to B. dilutior in external characters and shares with it the notched parameres. It may be distinguished from B. dilutior by the elytral punctation distinct on a broad surface of the disc and the internal sac of the aedeagus lacking basal tuft of spine-like structures.
