Head excavated, shiny, slightly granulated; frontal line complete; occipital carina absent; POL = 1; OL = 2; OOL = 8. Palpal formula 4/2. Pronotum shiny, unsculptured, impressed by slight transverse furrow. Scutum granulated. Metanotum transversely striate, with rounded sides ( Fig. 18 ). Meso-metapleural obsolete. Metathorax + propodeum usually completely transversely striate or rugose; occasionally with anterior surface shiny, unsculptured. Protarsal segments in following proportions: 20:4:5:18:27. Enlarged claw ( Fig. 38 ) with one large subapical tooth and one row of 6–8 lamellae. Segment 5 of protarsus ( Fig. 38 ) with two rows of about 19–34 lamellae; distal apex with about 8–9 lamellae. Tibial spurs 1/0/1.

MALE. Fully winged; length 2.2 mm. Head black, except mandible brown; antenna brown; mesosoma and metasoma black; legs brown. Antenna filiform, with segment 3 about four times as long as broad (8:2); antennal segments in following proportions: 4.5:4:8:8:9:8:7:7 (segments 9 and 10 missing in single known male specimen). Head swollen, shiny, unsculptured, granulated only in front of anterior ocellus; frontal line absent; occipital carina incomplete, only shortly present behind posterior ocelli; POL = 5; OL = 2; OOL = 3; greatest breadth of posterior ocelli slightly longer than OL (2.5:2). Palpal formula 4/2. Maxillary palpus with segment 4 about twice as long as segment 3 ( Fig. 39 ). Scutum dull, granulated.
