3.3 Baeocera repleta nov.sp. (Figs 14-17)

Type material: Holotype ♂, CHINA: Yunnan [CH07-16A] Baoshan Pref., mountain range 14 km E Tengchong , 1850 m, 25°00’28’’N 98°38’07’’E, field edge, compost and debris sifted, 1.VI.2007, M. Schülke ( ZMUB) . Paratypes: 3♂♂, with the same data as the holotype ( ZMUB, MHNG).

Description: Length 1.36-1.50 mm, width 0.94-0.97 mm. Body blackish-brown to black, femora and tibiae reddish-brown, tarsi and antennomeres I to VI lighter, almost yellowish, antennomeres VII to XI light brown. Head with interocular distance about three eye widths. Length/width ratios of antennomeres as: III 30/6: IV 30/6: V 35/6: VI 32/6: VII 40/8: VIII 35/6: IX 43/12: X 42/14: XI 50/15. Pronotum and elytra not microsculptured, with lateral contours separately arcuate. Pronotal punctation very fine and sparse, consisting of punctures hardly visible at 20x magnification. Exposed tip of scutellum minute. Elytra with lateral margins almost evenly rounded, sutural striae not shortened, parallel, curved along basal margin and extended to basal mid-width to form basal striae not joined to lateral striae. Elytral punctation coarse and dense, covering entire disc, punctures sharply delimited, puncture intervals mostly about two to three times as large as puncture diameters. Hind wings not reduced. Hypomera impunctate. Mesepimera about three times as long as wide and as intervals to mesocoxae. Centre of metaventrite with small impunctate area, remaining surface of metaventrite with coarse and dense punctation, punctures on lateral areas somewhat elongate, usually larger than puncture intervals. Submesocoxal lines convex, submesocoxal areas 0.03 mm, as third of intervals to metacoxae. Metanepisterna fused, sutures indicated by outer puncture rows of metaventrite. Ventrite 1 with punctation coarse and rather dense, less dense than on metaventrite, basal puncture row not interrupted in middle, consisting of somewhat elongate punctures. Following ventrites extremely finely punctate. Tibiae straight.

Male characters: Protarsomeres 1 to 3 slightly wider than protarsomeres IV. Aedeagus as Figs 14-17, 0.42-0.43 mm long.

Female characters: Unknown.

Differential diagnosis: This new species is a member of the B. lenta group. Its aedeagus is similar to that of B. longicornis ( LÖBL, 1971) , B. keralensis LÖBL, 1979 and B. rufula (LÖBL, 1973) . The new species may be readily distinguished from them by the coarsely punctate ventrite 1, and from B. longicornis and B. rufula by the basal striae of elytra not joined with the lateral striae. It also differs drastically from B. rufula by the larger body and the entire elytra coarsely punctate.

Etymology: The species epithet is a Latin adjective meaning completed.
