Diagnosis.

Apex of ovipositor sheath black or slightly brown (Fig. 31), if rather pale apically then pale part shorter than 0.3 times hind basitarsus; ovipositor sheath 0.8-1.3 times as long as hind tibia and 0.4-0.8 times as long as hind tibia and tarsus combined; occipital carina obsolescent medio-dorsally (Figs 29, 33) and rather protruding ventro-posteriorly (Fig. 24); antesternal carina narrow; head, laterally mesosoma and scape black; head in anterior view slightly protruding below lower level of eyes by less than basal width of mandible and mandibular condylus near lower level of eyes (Figs 28, 35); in lateral viewcondylarincision of malar space close to eye (Fig. 24); clypeus with small depression or depression obsolescent; eyes shortly setose; fourth and fifth antennal segment 1.1-1.3 (♀)-1.4 (♂) and 0.9-1.1 (♀)-1.4 (♂) times as long as third segment, respectively (Figs 32, 37); apical antennal segment at most 1.2 times as long as third antennal segment and its colour similar to colour of medial segments; antenna of female may be partly yellow-brown; mesoscutum and head similarly coriaceous, at most mesoscutum superficially rugulose (Figs 26, 34); propleuron robust and about 0.8 times as long as mesoscutum in front of tegulae (Fig. 25); hind coxa often transversely rugose dorsally, but sometimes mainly coriaceous; hind tibia robust, with a distinct subbasal ivory ring and swollen, resulting in a distinctly convex ventral border (Fig. 27, 36); hind basitarsus comparatively long (Fig. 27, 36); hind tibial spurs yellow-brown or brown; hind tarsus brown, dark brown or black; incision of hypopygium shallow.

Metasoma. Ovipositor sheath 0.2 times as long as body, 0.3 times as long as metasoma and 0.9 times as long as hind tibia; sheath apically dark brown; hypopygium shallow v-shaped apically.

Colour. Black or black-brown; second–fourth metasomal tergites apically and antenna (except for four black basal segments) more or less brown, tegulae and legs largely dark brown, but hind tibial spurs pale brown and hind tibia with large ventral subbasal patch ivory; pterostigma brown.

Male. Paratype. Head behind eyes roundly narrowed in dorsal view (Fig. 33); occipital carina distinctly pigmented, narrow and non-lamelliform medio-dorsally (Fig. 33); face wide (Fig. 35); third antennal segment about 1.7 times as long as second segment (Fig. 37); fourth segment 1.4 times as long as third segment, as fifth segment, and 0.8 times as long as second and third segments combined; vertex coriaceous, matt; eye glabrous; frons rather convex and anterior ocellus above upper level of frons (Fig. 35); propleuron robust and 0.8 times as long as mesoscutum in front of tegulae; antesternal carina non-lamelliform and narrow; mesoscutum densely coriaceous, mixed with fine transverse rugulosity and posteriorly distinctly rugose (Fig. 34); hind coxa slender in dorsal view; hind basitarsus transversely rugose dorsally; hind leg coloured as in female but hind tarsus largely brown (Fig. 36); apical half of first metasomal tergite and second tergite black; paramere black apically; body length 9.7 mm. Very similar to female, but slightly more coarsely sculptured.

Variation. Female: body length 8.7-14.0 mm, ovipositor sheath 0.8-1.3 times as long as hind tibia. Temple 0.6-0.7 times as long as eye in dorsal view; occipital area towards inside concave more or less; third antennal segment 1.5-1.7 times as long as second segment, fourth antennal segment 1.1-1.3 times as long as third segment, fifth antennal segment 0.9-1.0 times as long as third segment; OOL 1.3-1.4 times as long as diameter of posterior ocellus; minimum width of malar space 0.3-0.5 times as long as second antennal segment; length of hind femur, tibia and basitarsus 4.1-4.3, 3.4-3.6 and 4.9-5.4 times their width, respectively; ovipositor sheath black, 1.0-1.5 times as long as hind tibia.
