Diagnosis.

The combination of lacking a medio-posterior depression of the mesoscutum and the slender first metasomal tergite with a long median carina makes this species easy to separate from all other species in China.

Description.

Female from Liuba, length of body 3.7 mm, of fore wing 4.1 mm.

Head. Antenna with 39 segments and 1.3 times as long as fore wing; third segment 1.2 times as long as fourth segment, length of third, fourth and penultimate segments 3.0, 2.4 and 1.3 times their width, respectively (Fig. 42 ); length of maxillary palp 1.3 times height of head; labial palp segments slender; occipital carina far separated from hypostomal carina and carina dorsally absent; hypostomal carina wide; length of eye in dorsal view 3.0 times temple; frons shallowly depressed, with oblique striae and glabrous, laterally punctate and setose; face punctate, medially elevated (Fig. 39 ); width of clypeus 3.0 times its maximum height and 0.6 times width of face; clypeus moderately convex, punctate and protruding, straight and thin ventrally (Figs 33 , 38 ); hypoclypeal depression medium-sized (Fig. 39 ); malar suture absent; length of malar space 0.5 times basal width of mandible; mandible triangular and with narrow ventral carina (Fig. 38 ).

Mesosoma. Length of mesosoma 1.2 times its height; pronope absent; pronotal side smooth, only anteriorly and postero-ventrally crenulate; epicnemial area crenulate; precoxal sulcus wide and mainly punctate (Fig. 35 ), nearly up to anterior margin of mesopleuron; remainder of mesopleuron smooth; pleural sulcus smooth; anterior groove of metapleuron crenulate; notauli absent on disc, only anteriorly with pair of largely narrow and short smooth impressions (Fig. 36 ); mesoscutum largely glabrous; medio-posterior depression of mesoscutum absent; scutellar sulcus rather wide and crenulate; scutellum slightly convex medially, smooth and glabrous; propodeum with nearly complete irregular medio-longitudinal carina with crenulae and remainder smooth (Figs 36-37 ).

Wings. Fore wing (Fig. 34 ): pterostigma triangular; 1-R1 ending at wing apex and 1.6 times as long as pterostigma; r:3-SR:SR1 = 3:39:60; 2-SR:3-SR:r-m = 23:40:11; r widened; 1-M nearly straight; SR1 slightly curved; m-cu and cu-a postfurcal; first subdiscal cell closed, CU1b short; apical 0.2 of M+CU1 sclerotized. Hind wing (Fig. 34 ): M+CU:1-M:1r-m = 22:20:13; cu-a straight; m-cu completely absent.

Legs. Length of femur, tibia and basitarsus of hind leg 5.0, 10.0 and 5.0 times as long as wide, respectively; hind femur and tibia with long setae (Fig. 41 ).

Metasoma. Length of first tergite 1.5 times its apical width, its surface rather slightly convex medially, finely rugulose, with median carina and with dorsal carinae remaining separated (Fig. 37 ); second tergite smooth, with pair of large basal depressions; following tergites smooth; length of setose part of ovipositor sheath 0.07 times fore wing and 0.2 times hind tibia (Fig. 41 ).

Colour. Black; palpi and legs (but tarsi brown) ivory or white; scapus and pedicellus ventrally, mandible (except black teeth), tegulae and head (except dark brown stemmaticum and posterior part of head yellow, but frons and face brownish medially (Fig. 39 ); wing membrane subhyaline; base and apex of ovipositor sheath dark brown; intermediate part of ovipositor sheath and veins of basal half of wing brown; pterostigma and remainder of veins dark brown.

Variation.

Length of body 2.9-3.7 mm, of fore wing 3.1-4.1 mm; antennal segments of ♀ 35(1) or 39(1), length of first tergite 1.4-1.5 times its apical width, length of setose part of ovipositor sheath 0.07-0.10 times fore wing and 0.2-0.3 times hind tibia.

Distribution.

China (Fujian, Hunan, *Shaanxi), Far East Russia, Japan, Korea. The record from Spain ( Avinent and Jiménez 1987) needs reconfirmation.

Biology.

Unknown.
