Re-description.

Female (holotype).

Length. Body 1.8 mm, fore wing 2.0 mm, hind wing 1.4 mm.

Head. In dorsal view, 1.9 times as wide as long, 1.3 times as wide as mesoscutum, smooth, with temple rounded behind eyes. Antenna 22-segmented, 1.2 times as long as body. Scape 2.0 times as long as pedicel. First flagellar segment 2.2 times as long as its apical width, 1.3 times as long as second segment. Second flagellar segment 1.8 times, third to 20th (apical) segments 1.6-1.8 times as long as their maximum width. Eye in lateral view 1.6 times as high as wide and 1.8 times as wide as temple medially. POL 0.9 times OD; OOL 2.6 times OD. Face 1.4 times as wide as high, with sparse setae medially, punctate-rugulose medially and smooth laterally; inner margins of eyes subparallel. Clypeus 2.9 times as wide as high, slightly concave ventrally. Mandible almost parallel-sided, 1.2 times as long as its maximum width. Upper tooth very small and obtuse; middle tooth rather narrow and longer than lower tooth, weakly directed upwards; lower tooth narrow, round, with several long outstanding curved setae.

Mesosoma. In lateral view 1.4 times as long as high. Mesoscutum (dorsal view) 0.7 times as long as its maximum width, smooth, sparsely setose. Notauli mainly absent on horizontal surface of mesoscutum. Mesoscutal pit absent. Prescutellar depression smooth, with median and lateral carinae, 1.7 times as long as its maximum width. Precoxal sulcus present, crenulate, short, not reaching anterior and posterior margins of mesopleuron. Posterior mesopleural furrow smooth. Propodeum with large, wide and mainly smooth but partly rugulose pentagonal areola; basolateral areas smooth. Propodeal spiracles medium-sized, diameter 0.3 times distance from spiracle to anterior margin of propodeum.

Wings. Fore wing 2.5 times as long as its maximum width. Marginal cell ending at apex of wing, 3.9 times as long as its maximum width. Vein 3-SR 1.8 times as long as vein 2-SR. Vein SR1 2.3 times as long as vein 3-SR. Vein 3-SR 3.7 times as long as vein r. Vein r much longer than pterostigma width. First subdiscal cell 2.5 times as long as its maximum width. Hind wing 5.3 times as long as its maximum width.

Legs. Hind femur 3.8 times as long as its maximum width. Hind tibia weakly widened to apex, 6.4 times as long as its maximum subapical width, 1.1 times as long as hind tarsus. First segment of hind tarsus 1.7 times as long as second segment.

Metasoma. First tergite widened towards apex, 1.5 times as long as its apical width, sparsely striate laterally but rugose in medio-basal half. Ovipositor 1.6 times as long as first tergite, 0.5 times metasoma, approximately as long as hind femur.

Colour. Body, flagellar segments of antenna dark brown. Hind femur and tibia, mandible, pterostigma, fore and middle legs and hind tarsus light brown to reddish brown. First metasomal tergite similar colour to second and third tergites. Wings almost hyaline.

Male. Unknown.
