( Figure 3 A–E)

Holotype

Female, length of body 6.2 mm and of forewing 6.0 mm.

Head

Antenna with 38 segments, third antennal segment 1.2 times length of fourth segment, lengths of third, fourth and penultimate segments 2.2, 1.9 and 1.2 times their width, respectively; maxillary and labial palpi with five and three segments, respectively; length of maxillary palp 0.5 times height of head; length of eye in dorsal view equal to length of temple; ocellar–ocular distance:diameter of ocellus:posterior ocelli is 17:10:10; frons very narrow, anterior ocellus almost at level of antennal sockets and distance between anterior ocellus and posterior ocelli slightly more than that between posterior ocelli; frons and vertex smooth, densely setose; face and clypeus smooth; distance from upper margin of strongly enlarged anterior tentorial pits slightly more than distance to antennal socket; clypeus with medium-sized ventral lamella laterally and medially obsolescent; length of malar space 0.9 times basal width of mandible; malar suture absent; mandible rather twisted apically, upper tooth somewhat longer than second tooth and with convex outer side.

Mesosoma

Length of mesosoma 1.3 times its height; side of pronotum, mesopleuron and metapleuron smooth; ventral half of mesopleuron and metapleuron densely setose; precoxal sulcus absent; notauli complete, narrow and smooth; mesoscutum densely setose; scutellar sulcus smooth, deep and rather short; scutellum rather flat and densely setose; surface of propodeum smooth, long and densely setose; propodeal tubercle medium-sized and short elliptical ( Figure 3E ).

Wings

Forewing: r strongly oblique and equal to width of pterostigma ( Figure 3A ); r:3- SR:SR1 is 7:5:24; 1-CU1:2-CU1 is 3:25; 2-SR:3-SR:r-m is 12:5:6; m-cu antefurcal and converging to 1-M posteriorly; cu-a long and parallel to 3-CU1; CU1b much shorter than vein 3-CU1. Hind wing: with four hamuli; M+CU:1-M is 24:7.

Legs

Hind coxa smooth; hind femur densely setose; tarsal claws simple, long setose; fore tarsus 1.2 times longer than tibia; lengths of femur, tibia and basitarsus 4.2, 6.9 and 7.6 times their width, respectively; hind tibial spurs 0.35 and 0.40 times as long as hind basitarsus.

Metasoma

Length of first tergite 0.8 times its maximum (5subapical) width, its surface smooth and lateral areas comparatively narrow ( Figure 3B ), its spiracles strongly protruding; no laterope; third tergite rather transverse, three times wider basally than its median length ( Figure 3B ); ovipositor curved downwards, its sheath triangular and only apical 0.6 setose; length of ovipositor sheath 0.03 times as long as forewing; hypopygium large and apically truncate.

Colour

Yellowish-brown; antenna, head (but clypeus and ventrally malar space yellowish) black; palpi, fore tarsus (but telotarsus dark brown) and middle tarsus (but basally brownish and telotarsus apically darkened), middle coxa largely, middle and hind trochanter and trochantellus and spiracular tubercles of first tergite pale yellowish; hind coxa and femur and remainder of first tergite yellowish-brown and remainder of legs, scutellum and metanotum posteriorly, wing veins and pterostigma dark brown; wing membrane dark brown; mesosoma and metasoma largely covered with long and dense golden setosity.

Biology

Unknown.

Material
