Female. Head. Eyes oval, medium sized, sparsely setose. Malar space equal to 0.2 of longitudinal eye diameter. Tentorial index 0.3. Clypeus oval with 5 setae. Maxillary palps with four palpomeres, labial palps with two palpomeres. Antenna with 14–15 antennomeres, filiform, setae on flagellomeres semierect, subequal to half of flagellomere diameter. Flagellomere 1 (F1) about 4.7 (4.3–5.1)× as long as wide, without longitudinal placodes. F2 3.4× as long as wide, without longitudinal placodes. F3, F4 and F5 with 1, 1–4 and 4–5 longitudinal placodes, respectively. F1 1.3× longer than F2.

Mesosoma. Notaulices incomplete, visible in anterior part of mesoscutum. Dorsal surface of mesoscutum sparsely setose. Head width/mesoscutum width ratio 1.3. Propodeum without a central areola, with two postmedian carinae at the base ( Fig. 7b ).

Fore wing ( Fig. 8b ). Wing length about 1.8 (1.7–1.9) mm, width 0.7 mm. Stigma narrow, about 4.8 (4.4–5.4)× as long as wide and about 3.3 (2.9–4)× as long as distal abscissa of R1. Vein m-cu visible only in first third, remain- der colourless or completely absent. Vein 2RS visible only in first half. Veins r and 3RS distinct, 3RS short.

Metasoma. Petiole 1.8× as long as wide at spiracles. Dorsal disc of petiole smooth, with 2–4 long setae on each side. Ovipositor sheath needle shaped, only slightly widened ventrally. Ovipositor sheath length/width ratio 4.8 ( Fig. 9b ).

Colour. Head brown, eyes black, mouthparts light brown, antenna brown. Mesonotum brown, propodeum and legs light brown. Wings hyaline with brown venation. Petiole, rest of metasoma and ovipositor sheath light brown. Body length 2.4 mm.

Male. Head. Eyes oval, medium sized, sparsely setose. Malar space equal to 0.3 of longitudinal eye diameter. Tentorial index 0.5. Clypeus oval with 5–6 setae. Maxillary palps with four palpomeres, labial palps with two palpomeres. Antenna with 17 antennomeres, filiform, setae on flagellomeres semierect, subequal to half of flagellomere diameter. Flagellomere 1 (F1) about 2.2 (2.1–2.3)× as long as wide, with 7 longitudinal placodes. F2 1.9× as long as wide, with 7 longitudinal placodes. F3, F4 and F5 with 7, 6 and 5 longitudinal placodes, respectively. F1 1.1× longer than F2.

Mesosoma. Notaulices incomplete, visible only in anterior part of mesoscutum. Dorsal surface of mesoscutum sparsely setose. Head width/mesoscutum width ratio 1.3. Propodeum without a central areola, with two postmedian carinae at the base.

Vein m-cu visible only in first third, remainder colourless or completely absent. Vein 2RS visible only in first half, sometimes completely absent. Veins r and 3RS distinct, 3RS short.

Metasoma. Petiole 1.6× as long as wide at spiracles. Dorsal disc of petiole smooth, with 1–3 long setae on each side.

Colour. Head, antenna, and mouthparts light brown. Mesonotum brown, propodeum and legs light brown. Wings hyaline with brown venation. Petiole and rest of metasoma light brown. Body length 2 mm.
