Diagnosis.

Apex of ovipositor sheath narrowly ivory (Fig. 224); ovipositor sheath 1.1-1.2 times as long as body; occipital carina narrow, non-lamelliform medio-dorsally (Fig. 217) and protruding laterally (Fig. 217); propleuron robust, 0.8-1.0 times as long as mesoscutum in front of tegulae (Fig. 218); antesternal carina narrow; head, laterally mesosoma and scape brown; head in anterior view not protruding below lower level of eyes and mandibular condylus near lower level of eyes (Fig. 221); in lateral viewcondylarincision of malar space close to eye (Fig. 217); clypeal ventral depression obsolescent and lateral corners rather protruding forwards; eyes glabrous; fourth and fifth antennal segment 1.2-1.5 and 1.0-1.5 (♀) (of ♂ 1.4-2.0 and 1.4-1.8) times as long as third segment, respectively (♂ Fig. 226); apical antennal segment of ♀ 1.1 [absent in HT] times as long as third antennal segment and brown, as colour of medial segments; antenna of female brown; mesoscutum and head with satin sheen, head dorsally very finely punctulate and mesoscutum coriaceous-punctulate between many large punctures, punctate-rugose medio-posteriorly (Figs 219, 222; cf. ♂ Fig. 227); hind coxa transversely rugose dorsally, interspaces smooth or rugulose; hind tibia rather slender, brown subbasally, without an ivory ring, with a distinctly convex ventral border (Fig. 220); hind basitarsus comparatively long and entirely brown (Fig. 225); hind tibial spurs dark brown; apical half of hypopygium incised.

Description.
