Description

Female. Length of body about 2.3 mm (Fig. 2 View Figure 2 A). Length of forewing 1.9 mm (Fig. 2 View Figure 2 K).

Head. Eyes oval, sparsely setose. Tentorial index 0.14 (Fig. 2 View Figure 2 D). Clypeus oval with seven setae. Malar space 0.08 times as long as longitudinal eye diameter. Antenna 11-segmented (Fig. 2 View Figure 2 B). F1 slightly shorter than F2 (F2 1.07 times as long as F1) (Fig. 2 View Figure 2 C). F1 and F2 5.0 and 4.1 times as long as their width at the middle, respectively. F1 without longitudinal placodes and F2 with 3-4 longitudinal placodes. Maxillary palp with four palpomeres, labial palp with two palpomeres. Ratio of eye to temple in dorsal view 0.6. Face width/height ratio 1.2 (Fig. 2 View Figure 2 D).

Mesosoma. Mesoscutum with notaulices on anterior part, dorsal surface smooth, two rows of scarcely setose start at end of notaulus (Fig. 2 View Figure 2 E). Head width/mesoscutum width ratio 1.3. Propodeum areolated, areola length/width ratio 1.2 (Fig. 2 View Figure 2 F). Pterostigma 3.5 times as long as width. Ratio of pterostigma length to R1 vein (= metacarpus) length 2.5 (Fig. 2 View Figure 2 K). r and RS veins extended.

Metasoma. Petiole 2.0 times as long as wide at spiracles (Fig. 2 View Figure 2 I and J). Ovipositor sheath elongate, gently concave on ventral margin. Ratio of ovipositor sheath width/length 2.8 at base (Fig. 2 View Figure 2 G). Anal prongs (= accessory prongs) long and straight upwards, bifurcated on apical one-third to two-thirds (apical one-third are four, apcial half is two, apical two-third is one), each having one claw-like apical bristle and one seta at apex with two or three setae at dorsal side (Fig. 2 View Figure 2 H).

Colour. Antenna brown; scape, pedicel, F1 and F2 yellowish-brown, sometimes dorsal part of F2 brown; Head, face and clypeus with mouth-parts dark brown. Dorsal side of mesoscutum and metasoma dark brown, except light brown propodeum and yellowish-brown petiole. Legs yellowish-brown with dark apices.

Parasite of: T. arundinariae on Phyllostachys bambusoides .

Notes

In the original description, the antenna of this species was 13-segmented. However, it was a mistake in the email from the author. This species is really 11-segmented, but two segments are artificially repeated in the line drawing.
