Antenna clavate; antennomeres in following proportions: 8:5:19:10:8:7:6:6:4:8. Head ( Fig. 231C ) excavated, dull, granulate; frontal line complete; occipital carina shortly present behind and on sides of lateral ocelli; POL = 1; OL = 1.5; OOL = 8; greatest breadth of lateral ocellus about as long as OL. Palpal formula 6/3. Pronotum crossed by strong transverse impression, shiny, unsculptured. Mesoscutum shiny, unsculptured, about twice as long as broad (11:6) (shortest breadth), laterally with two pointed apophyses ( Fig. 230I ). Mesoscutellum shiny, flat, unsculptured. Length of mesoscutum + mesoscutel-lum about 3 × as long as breadth of mesoscutum (17:6). Metanotum shiny, unsculptured, sloping anteriorly, not or weakly excavated behind mesoscutellum ( Fig. 239A ), with sides rounded, not protruding. Metapectal-propodeal disc ( Fig. 231A, B ) fusiform, shiny, unsculptured; propodeal declivity with transverse striae on distal half. Meso- pleuron and metapleuron unsculptured. Meso-metapleural suture distinct and complete. Protarsomeres ( Fig. 231D ) in following proportions: 16:3:5:17:26. Enlarged claw ( Figs 212B , 235C ) with one small subapical tooth and one row of five-six peg-like setae + one bristle. Protarsomere 5 ( Figs 212B , 235C ) without proximal serrate area, with two rows of 3–4 (proximal) + 18–19 lamellae; apex with five-seven lamellae. Tibial spurs 1/0/1.
