Apical fifth of ovipositor sheath white (Fig. 204), 1-2 times as long as hind basitarsus; head distinctly excised posteriorly (♂ Fig. 215) or truncate (♀ Fig. 207), with a small triangular depression in front of wide to medium-sized lamelliform occipital carina medio-dorsally, with indistinct minute tubercles and deep cleft (Figs 200, 209); antesternal carina non-lamelliform and narrow (Fig. 201); propleuron 1.0-1.1 times as long as mesoscutum in front of tegulae and rather slender (Fig. 201); head roundly narrowed behind eyes in dorsal view (Figs 207, 215); temple much shorter than eye in dorsal view; antennal segments unknown of types, according to original description third segment about 1.3-1.6 times as long as second segment; malar space partly absent and condylus nearly touching eye; frons and vertex finely densely punctulate and with distinct satin sheen; antero-lateral teeth of pronotum absent, only some what angulate; mesoscutum coriaceous and with satin sheen, with minute separate punctures and medio-posteriorly mainly coriaceous with some large oval and round punctures (Figs 202, 211); marginal cell of fore wing elongate; hind coxa moderately slender and largely coriaceous, but dorsally transversely rugose; ovipositor sheath about 0.8-1.1 times as long as body and about 1.3-1.6 times as long as metasoma; hind coxa and pronotal side black; hind basitarsus entirely dark brown and slender, rarely with ivory patch; hind tibia slender and bicoloured (dorsally dark brown, ventrally with rather small ivory subbasal patch).

Description.

Syntype, male, length of head and mesosoma (metasoma missing) 6.4 mm.

Vertex excised medio-posteriorly, with satin sheen and densely finely punctulate, moderately convex and with small triangular depression medio-posteriorly, with pair of minute tubercles (Figs 215, 216); head gradually narrowed behind eyes; temple 0.7 times as long as eye in dorsal view; third antennal segment (of male?) about 1.5 times as long as second segment according to original description; occipital carina wide lamelliform medio-dorsally (Fig. 209); ocelli comparatively small, OOL 1.4 times as long as diameter of posterior ocellus; face moderately narrow (Fig. 206, 214); malar space partly absent (Fig. 209).

Mesosoma. Length of mesosoma 2.1 times its height; pronotal side comparatively elongate and mainly coriaceous antero-ventrally; mesoscutum not protruding anteriorly; propleuron 1.1 times as long as mesoscutum in front of tegulae (Fig. 210); antesternal carina narrow and hardly lamelliform; mesoscutum coriaceous and with satin sheen, with minute separate punctures and medio-posteriorly mainly coriaceous with some large oval punctures (Fig. 211); scutellum coriaceous.

Wings. First discal cell parallel-sided and indistinct posterior corner (Fig. 213; cf. ♀ Fig. 208); marginal cell of fore wing slender.

Legs. Hind coxa largely coriaceous, with satin sheen, but partly finely transversely striate dorsally; length of hind femur, tibia and basitarsus 4.2, 4.8 and 6.2 times their width, respectively (Fig. 212).
