( Figs 4–6 , 20–22 )

Description. Female. Body length 2.45 mm. LFW 1.16 mm. Body entirely flattened, head 0.3x as high as long in lateral view.

Color. Head, dorsum and lateral of mesosoma, antenna dark castaneous; venter of mesosoma, mandible, legs (except tarsi), wing venation, posterior half of metasoma castaneous; palpi, tarsi, anterior half of metasoma light castaneous; wings hyaline.

Head ( Figs 4–5 ). Mandible slender, with four visible sharpened apical teeth; lowermost one large. Clypeus short; slightly projected, median lobe trapezoidal with apical margin roundly concave; medially elevated, but not carinate. Carina fronto-clypeal absent. Eye flat, with minute and sparse setae. First four antennomeres in ratio of about 11:6:3:4; flagellomere I as long as wide; flagellomere IX distinctly longer than wide. Frons coriaceous with just few small punctures. LH 1.4x WH; WF 0.94x HE; VOL 1.03x HE; OOL 1.43x WOT. Frontal angle of ocellar triangle obtuse; ocellar triangle almost touching vertex. Vertex straight; corner rounded. Side of head almost parallel behind eye. Occipital carina absent. First two maxillar palpomeres distinctly shorter and wider than others, III-IV distal ones progressively wider apicad. Labial palpomeres shorter than maxillar ones.

Mesosoma ( Fig. 4–6 ). Pronotal disc with top surface 2.2x as long as mesoscutum; ecarinate. Pronotal collar without groove. Mesoscutum with parapsidal furrow narrow, straight, absent on anterior half of mesoscutum, almost reaching tegula. Mesoscutum-mesoscutellar sulcus absent. Forewing fully developed; 3.1x as long as wide; subcostal vein 0.27x as long as LFW; median vein present in proximal region, 0.1x as long as subcostal vein; pterostigma small and triangular ( Fig. 21 ). Hind wing with three distal hamuli ( Fig. 22 ). Propodeal disc coriaceous, 1.15x as long as median width, progressively narrowing posteriorly; transverse posterior and lateral carinae absent; median carina absent; lateral of propodeum coriaceous with spiracles circular; declivity of propodeum coriaceous without median or lateral carinae. Anterior margin of propleuron almost reaching anterior margin of pronotal disc level in dorsal view. Mesopleuron ( Fig. 20 ) with subtegular groove poorly outlined; lower and anterior foveae absent, mesopleural pit inconspicuous and shallow. Profemur 2.27x longer than wide.

Metasoma. Not petiolate; polished; 1.55x longer than mesosoma. Tergite II slightly longer tergite I, posterior margin slightly excavated medially.
