Redescription.

Female. Length of body about 2.1 mm (Fig. 5 A ). Length of forewing 1.3 mm (Fig. 5 J ).

Head. Width of head 1.5 × its maximum length in dorsal aspect; occipital carina broad and moderately concave anteriorly; maximum head length 1.3 × as long as its minimum length; head 1.2 × wider that mesosoma, with sparse long setae; eye 1.7 × as long as temple in dorsal aspect; OOL 3.0 × as long as posterior ocellus diameter; ratio of OOL: AOL: POL = 17: 10: 7 (Fig. 5 G ). Eyes oval, sparsely setose; face densely long setose, width / height ratio = 1.3; tentorial index = 0.32; clypeus oval and with 8 setae; malar space 0.2 × as long as longitudinal eye diameter (Fig. 5 D ). Antenna 12 - segmented; F 1 subequal to F 2 (F 2 0.9 to 1.1 × as long as F 1); F 1 and F 2 3.1–3.8 × and 3.4–3.6 × as long as their width at the middle, respectively; F 1 and F 2 with two and three longitudinal placodes, respectively (Fig. 5 B, C ). Maxillary palp with three palpomeres, labial palp with one palpomere.

Mesosoma. Mesoscutum with notauli on anterolateral margin, effaced dorsally; The precoxal sulcus is weakly impressed on the anterior part of the mesopleuron (Figs 5 E , 6 H ). Dorsal surface smooth, with two rows of four or five long setae along the dorsolateral part of mesoscutum; scutellum nearly triangular, with two long setae on each side (Fig. 5 E ). Propodeum areolated, areola length / width ratio = 1.2 (Fig. 5 F ). Pterostigma 2.5–2.7 × as long as width; pterostigma 0.8–0.9 × as long as vein R 1 (= metacarpus); r and RS vein extended (Fig. 5 J ).

Leg. Hind femur length / width ratio = 5.0; hind tibia length / width ratio = 11.0; hind femur: hind tibia: hind tarsus = 1: 1.6: 1.7 (Fig. 5 L, M ).

Metasoma. Petiole elongated, 3.1–3.3 × as long as wide at spiracles; distinctly prominent central carinae, situated along the dorsal surface of the petiole, start at the anterior part and bifurcate near spiracles; dorsolateral part of posterior spiracles concave on each side (Fig. 5 H, I ). Ovipositor sheath slender and long, wide at base, curved downwards; ratio of ovipositor sheath width / length 3.0 (2.9–3.1) at base and 8.5 (7.9–9.3) at tip (Fig. 5 K ).

Colour. Antenna brown; scape and pedicel brown, F 1 entirely or at least partly pale brown. Head and face dark brown, clypeus with mouthparts pale brown. Mesosoma and metasoma brown; mesoscutum dark brown; petiole pale brown. Legs pale brown with dark apices.

Distribution.

Europe ( Spain and Slovenia) and Oriental region ( China, Japan [from GenBank], and South Korea).
