Description

Female (holotype).— Head width 4.20 mm, body length 12.1 mm. HW 50, HL 36, UID 29, UFW 32, LID 31, DMA 31, HVO 5, WOC 13, MOD 3, OOD 8, IAD 8, ASD 4, AOD 9, ML 19, BMW 7, MSL 2.0, SL 14, SW 3, FL c. 33.— Eyes hairy; face wider than long; length malar space c. 0.25× basal mandibular width; clypeus protuberant, sagittally flattened or slightly depressed; basal suture shallow V-shape; basal width clypeus>2× length subantennal suture; supraclypeal area viewed laterally at distinct angle to base clypeus; epistomal suture between base of clypeus and base of mandible straight; distance from anterior tentorial pit to base of mandible 2× distance from pit to base clypeus; frontal carina ends in small tubercle on supraclypeal area; middle flagellomeres c. 1.2× as long as wide; inner hind tibial spur with c. 7 teeth; tarsal claws simple; pygidial plate entire, flat medially.— Labrum, rim of clypeus, distal ends of femora and anterior surface of fore tibia orange-brown. T 1–4 with narrow silver bands.— Clypeus weakly reticulate with large punctures, dense medially, close laterally; scutum with dull sheen, strongly pit-reticulate with close, small punctures.— Face with pale orange-brown hair, darker near ocelli, sparse on clypeus and supraclypeal area, dense elsewhere.
