Female (holotype): Body length 2.8 mm. Head rounded in anterior view, length 0.4 mm, width 0.85 mm; compound eyes not especially bulging, oval, large, well separated by 0.43 mm dorsally; basal part of palps not visible but maxillary palps with at least five palpomeres; labial palps with at least three palpomeres; slight, triangular, supra-antennal elevation above torulus, intertorular area flattened; toruli closer to each other than to inner margin of compound eyes; antennae 2.4 mm in length, inserted on frons below midpoint of compound eyes; scape and pedicel short and globular, flagellomeres cylindrical; lengths of antennomeres as follows (all in mm): scape 0.15, pedicel 0.10, flagellomeres 0.22, 0.20, 0.20, 0.20, 0.18, 0.15, 0.14, 0.14, 0.12, 0.12, 0.12, 0.12, 0.12, 0.15; malar space short, 0.15 mm in length. Mesosoma only laterally visible, 1.15 mm in length; pronotum 0.20 mm in length; mesoscutum 0.35 mm in length; mesoscutellum strongly convex, 0.30 mm in length; propodeum slightly rugose, 0.30 mm in length. Only left mid and hind legs are complete, but foreleg can be reconstructed by mixing right and left parts; no visible division of metatrochantellus; tarsi pentamerous, tarsomeres I–IV each with apicoventral plantar lobe (well visible on left metatarsus: Figs 5, 6D); pretarsal claws with small preapical tooth; leg measurements (all in mm): profemur (with protrochantellus) 0.85, protibia 0.50, protarsomeres I–V 0.30/0.15/0.12/?/?; mesofemur 0.75, mesotibia 0.72, mesotarsomeres 0.32/0.15/0.10/0.07/0.12; metafemur 0.95, metatibia 0.90, metatarsomeres 0.38/0.15/0.10/0.08/0.14. Forewing hyaline, length 2.4 mm, maximum width 0.95 mm, densely covered by microtrichia; all veins tubular except for nebulous crossveins 2rs-m and 2m-cu, thus only cells [2Rs] and [2M] pseudo-opened apically (Fig. 7A); 1rs-m not aligned with r-rs; 2m-cu curved at each distal end; veins M and Cu reaching wing margin, with distal end of Cu strongly bent posteriorly; cell [1R1] longer than both cells [1Rs] + [2Rs]; cell [1Rs] about half the surface of cells [1M] and [2Rs]; vein r-rs emerging at two-thirds from base of pterostigma; cell [2R1] short, with vein Rs slightly anteriorly bent distad 2rs-m. Hind wing hyaline and densely covered by microtrichia, length 1.65 mm, maximum width 0.45 mm; five strong hamuli present on costal vein in distal half of wing (Fig. 7B); distal sections of veins Rs and Cu reaching nebulous wing margin; vein A lost beyond cu-a. Metasoma pedunculate, elongate and globoid, length 1.3 mm, greatest height 0.5 mm; sterna hard, convex; no apparent metasomal armature on sternum II or III; cerci very short; ovipositor moderately exserted, first valvula 0.65 mm long (as preserved), second valvula 0.35 mm long, apically with four dorsal teeth, with sheaths covered by very short, sparse setae (Figs. 4, 5A, 5C).  Male: Very similar to female except in following minor differences: Body length 3.63 mm; tarsi without plantar lobes; metasoma slightly longer than mesosoma.
