FIGS 51-58

(51-54) Baeocera procerula sp. n., aedeagus (51, 54) in dorsal and lateral views, paramere (52) and internal sac (53) in dorsal view; scale bar = 0.1 mm for aedeagus, = 0.05 mm for paramere and internal sac. (55-58) Baeocera wolfgangi sp. n., aedeagus (55, 58) in dorsal and lateral views, paramere (56) and internal sac (57) in dorsal view; scale bar = 0.1 mm for aedeagus, = 0.05 mm for paramere and internal sac.

OTHER MATERIAL EXAMINED: 6 additional specimens likely conspecific but in poor condition, with the same locality data but 100-200m, 21. and 27.II.1991 ( SMNS, MHNG) .

DESCRIPTION: Length 1. 0-1.09 mm, width 0.70-0.78 mm. Body and femora dark brown, tibiae lighter reddish-brown, tarsi and antennae lighter than tibiae, yellowish. Body convex dorsally. Eyes large. Length ratio of antennomeres as: III 7: IV 8: V 9: VI 9: VII 12: VIII 11: IX 12: X 12: XI 14. Antennomeres III, V and VI evenly narrow, V and VI each about 5 times as long as wide; IV slightly narrower than VI; VII moderately wide, about 4 times as long as wide; VIII slightly wider than VI, distinctly narrower than VII, about 4.5 times as long as wide; IX to XI each distinctly wider than VIII, XI about 3 times as long as wide. Pronotum and elytra without microsculpture, with lateral contours separately arcuate; pubescence hardly visible at 50 times magnification. Pronotum very finely punctate, with lateral margins strongly convex, middle section of lateral margin carinae usually visible in dorsal view. Scutellum concealed. Elytra almost covering apex of abdomen, with lateral carinae concealed, or shortly exposed near base. Elytron with sutural stria shallow, curved at base to form basal stria reaching about mid-width of elytral base. Elytral punctation coarse and dense on entire discal surface, with puncture intervals mostly larger than puncture diameters, often some punctures about as large as intervals. Hind wings not reduced. Hypomera impunctate. Mesepimera flat, about 4 times as long as wide and about 3 times as long as interval to mesocoxa. Metaventrite somewhat convex in middle, with impunctate central surface small, around centre coarsely punctate. Lateral parts of metaventrite with irregular, coarse punctures larger than those around centre, not or slightly elongate and mostly smaller than 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 0.08 mm. Metanepisterna indistinct. Metepimera impressed at inner angle. Abdominal ventrite 1 lacking microsculpture, with punctation coarse on entire surface, basal punctures not or barely elongate, contiguous in middle, basal rugosity absent. Tibiae straight.

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

Figs 55-58, 0.25-0.28 mm long. Median lobe moderately sclerotized.

DISTRIBUTION: Philippines, Leyte.

ETYMOLOGY: The species in named in honour of my colleague and one of its collectors, Wolfgang Schawaller, Stuttgart, Germany.

COMMENTS: The aedeagal characters of this species suggest close relationship with B. louisi . These species may be however readily distinguished by the elytra entirely coarsely punctate and the basal striae ending about at basal mid-width in B. wolfgangi , while the coarse elytral punctation is restricted onto a lateral surface and the basal striae are complete, joined with the lateral striae in B. louisi .
