4 Anterior angles of pronotum (viewed from above) usually remarkably projecting laterally, lateral sides very concave 5 - Anterior angles of pronotum rectangular or forming an obtuse angle laterally, at most sometimes slightly protruding, lateral sides slightly concave or parallel on its anterior part 16 5 Lateral angles of propodeum fairly sharp, hardly extending beyond segment (fig. 89), Anterior corners of pronotum acute, surface of pronotum very roughly sculptured, with many large deep pits being several times larger than cephalic ones (fig. 88). Lateral parts of mesonotum finely shagreened, only with very small and scattered punctures. Tergite 2 with rather deep scattered punctures on its anterior two-thirds (fig. 90) 3.5 mm punctaticollls (Fouts, 1930) - Lateral spines of propodeum longer (fig. 93). Lateral sides of mesonotum at most with a few large punctures 6 6 Antennae unusually thick, not flattened, joints 2 and 5 as long (fig. 91) as broad, 7 slightly longer than broad (8 : 6.5). Lateral spines of propodeum stumpy, only half as long as propodeum (fig. 93). Head converging behind eyes, pronotum with sharp acute lateral corners (fig. 92). Basis of tergite 2 granulated, with scattered, distinct and rather deep punctures medially and laterally (fig. 94). 3.8 mm crassiantennls Móczár, 1976 - Antennae normal, not flattened, sometimes joint 2, mostly 5 and 7 remarkably longer than broad 7 7 Tergite 2 with finely scattered punctures (fig. 97). Lateral spines of propodeum short, distinctly shorter than half length of propodeum medially (fig.. 96). Scutellum not impressed medially. Anterior corners of pronotum with a small triangular protrusion, surface shagreened with larger, deep and dense punctures (fig. 95). Mandibles, clypeus, antennái joints 1-3, tegulae yellowish brown. 3.6 mm cambodianus Móczár, 1976 - Tergite 2 rather deeply and densely, sometimes partly distinctly punctured, while laterally there are smaller punctures between larger ones 8 8 Lateral margins of propodeum more or less convex at least up to spine 9 - Lateral margins of propodeum straight, or at most from spines diverging .... 12 9 Head, thorax largely red, postnotum and propodeum black. Ocelli forming an obtuse angle. Antennái joints rather thick, joints 4-5 shorter than 6-8 (fig. 101). Mesonotum with some larger deep punctures. Lateral spines of propodeum directed slightly outwards (fig. 99), about half as long as length of propodeum. 4. 5 mm kibissaensis sp. n. - Head at last partly, thorax entirely black 10 10 Head largely dark red, frons, vertex with an extend black spot, thorax and tergites 1-2 black, 3-6 yellowish red. Ocelli forming an acute angle (fig. 102). Antennái joints remarkably slender, joint 2 1.6 times longer than broad (fig. 104). Longitudinal furrow of mesonotum more or less margined (fig. 103), Lateral spine short, propodeum medially only 2.11 (holotype, fig. 103) - 2.22 (paratype) times longer than spine. Tergite 2 densely and deeply punctured (fig. 105) 4.1 mm wahlsi sp. n. - Head excepting mouth parts and clypeus, thorax and abdomen black, sometimes abdomen partly reddish translucent. Longitudinal furrow of mesonotum short, developed only apically. Joint 2 of antennae nearly as broad as long (figs 106, 111) 11 11 Larger species, 5.8 mm. Antenna! joints distinctly longer than Its width, joint 3 nearly twice as long as 2 (fig. 111). Propodeum longer than half diameter of its breadth (fig. 112). Antennae black, joints 1-2, partly, 3-5 and lower side yellowish red. Tergite 2 distinctly and posteriorly deeply punctured (fig. 110). Lateral spines nearly two-thirds as long as length of propodeum (fig. 112) laosensis Móczár, 1976
