Female. Body length 1.30 mm; fore wing length 1.20 mm.

Coloration. Head in frontal view dark green with metallic diffuse coppery lustre, in dorsal view dark blue-green with metallic diffuse coppery lustre; antenna with scape, pedicel, anelli and F1-F5 yellowish-brown, clava brown. Mesosoma, propodeum and all coxae dark blue-green with metallic diffuse coppery lustre; all femora, tibiae and tarsi yellow. Fore wing hyaline, venation yellowish-brown. Metasoma in dorsal view dark blue-green, in ventral view brown; ovipositor sheaths black.

Eye height 1.50 times eye length and 2.60 times as long as malar space. Distance between antennal toruli and lower margin of clypeus 0.60 times distance between antennal toruli and median ocellus. Antenna with scape 0.70 times as long as eye height and 1.07 times as long as eye length; pedicel 1.88 times as long as broad and 3.44 times as long as F1; combined length of pedicel and flagellum 0.78 times breadth of head; F1-F5 transverse with 1 row of sensilla; clava 2.00 times as long as broad, with small micropilosity area on C3 and C4.

Mt2 0.25 times median length of metasoma; Mt8 1.15 times longer than maximum width. Ovipositor sheath projecting slightly beyond apex of metasoma.

Male. Unknown.

Remarks.

The description of the species F. wuhuica by Xiao and Ye (2015) provides measurements that do not coincide with our measurements made during the study of the type material: body length 1.70 mm (redescription - 1.30 mm); head in dorsal view 3.17 times as broad as long (1.90); eye height 3.30 times eye length (1.50); fore wing 2.57 times as long as maximum width (2.82); M 1.33 times as long as P (1.66).

Distribution.

Peoples’ Republic of China (Anhui).
