Diagnosis. Female with disc of pronotum very humped, without a posterior transverse impression; notauli complete or hardly visible; segment 5 of fore tarsus with two rows of lamellae (Fig. 21). Male unknown.
Redescription. Female: fully winged; length usually 4.6–5.0 mm. Head black, except mandibles testaceous; antenna brown; occasionally antenna reddish, except segments 7–10 brown; mesosoma black; occasionally lateral regions and posterior margin of pronotum reddish; metasoma brown-black; legs brown, except tarsi testaceous. Antenna clavate; antennal segments in following proportions: 15:7:35:21:12:12:10:9:8:8; antennal rhinaria present in segments 6–10. Head weakly excavated, shiny, with face and vertex reticulate rugose and occiput granulated; frontal line complete; occipital carina incomplete, present behind and on sides of posterior ocelli, laterally extending beyond 0.5 length of OOL; POL = 3; OL = 2; OOL = 12; greatest breadth of posterior ocelli longer than OL (4:2); posterior ocelli touching occipital carina; temples distinct. Palpal formula 6/3. Pronotum hairy, crossed by a strong transverse impression; anterior collar smooth, without sculpture; disc very humped, with some longitudinal keels, without a posterior transverse impression (Fig. 20); posterior edges of pronotum rounded, not produced into lobes. Scutum hairy, reticulate rugose. Notauli absent; occasionally present and incomplete, but hardly visible. Scutellum completely reticulate rugose. Metanotum very short, reduced. Propodeum dull, completely reticulate rugose; posterior surface with two longitudinal keels. Forewing with two dark transverse bands; distal part of stigmal vein much longer than proximal part (21:9). Hind wing hyaline, distally darkened. Fore tarsal segments in following proportions: 24:2:8:15:32. Enlarged claw (Fig. 21) with a subapical tooth and a row of 12–15 peg-like hairs. Segment 5 of fore tarsus (Fig. 21) with two rows of about ten lamellae; distal apex with a group of about five lamellae. Tibial spurs 1/0/2.
Male: fully winged; length 2.6–4.1 mm. Head black, except mandibles testaceous; antenna testaceous; mesosoma black; metasoma brown; legs brown, except tarsi testaceous. Antenna filiform; antennal segments in following proportions: 5:5:15:11:10:10.5:9:8:7.5:9.5. Head dull, granulated and rugose; frontal line absent; face without a median keel between antennal toruli; occipital carina absent; temples absent; POL = 8; OL = 3; OOL = 5; greatest breadth of posterior ocelli longer than OL (4:3). Palpal formula: 6/3. Scutum and scutellum dull, granulated. Notauli complete, posteriorly separated; minimum distance between the notauli longer than greatest breadth of posterior ocelli (5:4). Metanotum shiny, smooth, without sculpture, except anterior margin rugose. Propodeum dull, reticulate rugose, without transverse or longitudinal keels. Forewing hyaline, without dark transverse bands; distal part of stigmal vein slightly longer than proximal part (15:13). Parameres (Fig. 22) with dorsal process short and located proximally.
