Metasoma. Petiole 2.5× as long as wide at spiracles. Dorsal disc of petiole moderatelly rugose, with 3–5 long setae on each side. Ovipositor sheath narrow, needle shaped. Ovipositor sheath length/width ratio 4.6 ( Fig. 9a ).

Colour. Head brown, eyes black, mouthparts light brown. Scapus, pedicel, and F1 yellow, remainder of antenna brown. Mesonotum, propodeum and legs brown. Wings hyaline with brown venation. Petiole and rest of metasoma brown, ovipositor sheath light brown. Body length 2.4 mm.

Flagellomere 1 (F1) 2.5× as long as wide, with 11–14 longitudinal placodes. F2 1.8× as long as wide, with 11–12 longitudinal placodes. F3, F4 and F5 with 13–14, 10–12 and 9–10 longitudinal placodes, respectively. F1 length equal to F2.

Mesosoma. Mesoscutum without notaulices. Dorsal surface of mesoscutum sparsely setose. Head width/mesoscutum width ratio 1.2. Propodeum areolated, with central pentagonal areola wide in the middle.
