description: <i>Baeocera kaibesara</i> <b>sp</b>. <i>n</i>. (Figs 8. 9) Holotype <i>&amp;male;</i> labelled: INDO MALUC F911074 Kai Besar G: Turkan 7.9.91. Leaf Litter Agosti (8) 300 m (MHNG) <i>Description</i>. Length 0.90 mm, width 0.65 mm. Head, body and femora uniformly reddish-brown, tibiae, tarsi and antennae body. Antennae comparatively long, antennomere XI about 1.1 times as long as X and 2.5 times as long as wide. Lateral contours of pronotum and elytra continuously convex. Pronotum not microsculptured, with sparse and very fine punctation, setation hardly visible at lOOx magnification. Lateral margins of pronotum convex, anterior margin wide, basal lobe small. Scutellum concealed. Elytra not microsculptured, weakly narrowed <i>apically</i>, almost completely covering abdomen, middle parts of lateral margins oblique, anterior third of lateral margin carinae visible in dorsal view, suturai striae shortened, starting posterior basal fifth of suturai length. Elytral punctation fine, fairly dense, puncture intervals mostly about twice as large as puncture diameters. Metathoracic wings not reduced, likely functional. Hypomera smooth. Mesepimera large, about 4 times as long as wide and about three times as long as intervals to mesocoxae. Metaventrite distinctly convex and impunctate in middle, lacking impression, finely punctate near impunctate centre, densely and coarsely punctate laterally, with <i>punctures</i> about as large as or distinctly larger than puncture intervals. Submesocoxal areas about 0.01 mm long, shortest interval to metacoxae about 0.10 mm. Metanepisternum almost completely concealed, indicated by outer puncture row of <i>metaventrite</i>. Metanepisternum almost completely concealed, its suture indicated by outer puncture row of metaventrite. Sternite 1 with fairly coarse and dense punctation covering entire surface, puncture intervals distinctly larger than puncture diameters, basal punctures not elongate, lacking basal wrinkles. Following sternites finely punctate. Tibiae straight. Male sexual characters. Protarsomeres 1 to 3 hardly widened. Aedeagus (Figs 8, 9) 0.26 mm long, symmetrical. Median lobe weakly sclerotized, with basal process inconspicuous, apical process gradually narrowed in dorsal view, weakly narrowed and with almost straight ventral side up to abruptly narrowed and inclined tip in lateral view. Paramères narrow, lacking lobes, hardly sinuate, slightly widened posterior level of tip of median lobe in dorsal view, widest in level of latter in lateral view. Internal sac with basal complex of sclerites, membranes lacking denticulate or hair-like structures. <i>Distribution</i>. Moluccas, Kai Besar Island. <i>Etymology</i>. The species epithet is the name of the island Kai Besar. <i>Comments</i>. The holotype has the right antenna broken off, and I refrained from mounting the left antenna on a slide. Therefore, the length/width ratios of antenno- meres is not given. The <i>species</i> is a member of the <i>B</i>. <i>lenta</i> group, and similar to <i>B</i>. biroi (Löbl, 1975). It differs from the latter by the shape of the apical part of the median lobe that is abruptly inclined, the apically widened paramères, and the less shortened suturai striae of the elytra.
