Female. Body length 2.1–2.6 mm (based on examined specimens).

Head: Subcircular, 1.1 × as wide as long ( Fig. 22 View FIGURE 22 -B); lateral temples slightly visible behind eyes; width of face (at widest) 0.5 × width of head; face slightly convex, 1.2 × as wide as long; lateral temples, vertex and dorsal occiput slightly rugulose, sparsely setose ( Fig. 22 View FIGURE 22 -B); area between antennal sockets with distinct carinate longitudinal ridge; eyes setose; POL 1.2 × OOL; ocelli forming an obtuse angle; antenna 0.9 × as long as body ( Fig. 22 View FIGURE 22 -A); first flagellomere 1.2 × as long as second flagellomere, 3.1 × as long as wide; second flagellomere 3.1 × as long as wide; terminal flagellomere acute, 2.9 × as long as wide.

Mesosoma: Mesosoma 1.4 × as long as high; mesoscutum rugose, setose ( Fig. 22 View FIGURE 22 -C); notauli impressed, meeting posteriorly, separated by a longitudinal ridge; medial furrow indistinct; scutellar lunules widest medially, divided by five carinae ( Fig. 22 View FIGURE 22 -C); area lateral to scutellar lunules flat; dorsal scutellum slightly rugose, convex, setose with marginal carinate groove laterally; propodeum with percurrent medial longitudinal carina; lateral pronotum with oblique, slightly crenulate furrow; mesopleuron sparsely setose anteriorly, smooth and glabrous postero-medially, epicnemal area setose with crenulate epicnemal furrow reaching anterior margin of mesopleuron; precoxal groove shallow, crenulate; hind coxa smooth associated with micropunctures, setose; hind femur 4 × as long as wide; hind tibia 7.5 × as long as wide; outer hind tibial spur 0.3 × as long as basitarsus.

Wings: Fore wing 3.2 × as long as wide; pterostigma 3 × as long as wide ( Fig. 22 View FIGURE 22 -F); areolet large, quadrangular ( Fig. 22 View FIGURE 22 -F); 1 -M straight or slightly curved; margin of vannal lobe convex and setose.

Metasoma: T 1 2 × as long as wide, rugose with medial groove, parallel sided, rounded apically ( Fig. 22 View FIGURE 22 -D & E); T 2 with indistinct median field ( Fig. 22 View FIGURE 22 -E); T 2 –T 7 smooth with sparse transverse row of setae posteriorly ( Fig. 22 View FIGURE 22 -E); ovipositor 0.4 × as long as hind basitarsus.

Colour: Body black, antenna reddish yellow except scape and apical 7 th– 8 th flagellar blackish, the tip of mandible yellowish brown, the rest black, maxillary palps yellow, tegulae and tergites T 2 –T 3 reddish yellow ( Fig. 22 View FIGURE 22 -E), sternites 1–3 yellowish white and hypopygium black, legs reddish yellow but hind coxa with basal part blackish and hind tibia with apical 1 / 4 blackish, all spurs pale yellow, fore and hind wings hyaline, pterostigma blackish with a yellow basal spot at basally, most of veins yellowish brown ( Fig. 22 View FIGURE 22 -F).

Male: Similar to female except body 2.3–2.7 mm long; antennae brownish black; penultimate flagellomere 1.6 × as long as wide.

Distribution. China (Fujian and Zhejiang) and India (Kerala).

Host. Unknown.

Discussion. This species is close to M. marshalli   in having the impressed notauli, mesoscutum with medial furrow, median field of T 2 faintly marked. It differs from M. marshalli   in the following characters: propodeum reticulate-rugose (in M. marshalli   propodeum coarsely rugose), hind coxa smooth basally (in M. marshalli   hind coxa sculptured or punctate basally), face punctate (in M. marshalli   face rugose or rugulose), mesosoma 1.4 × as long as high (in M. marshalli   mesosoma 1.7 × as long as high), scape black (scape reddish brown in M. marshalli   ), head 1.1 × as wide as long (in M. marshalli   head 2.1 × as wide as long).

Comments. Type material could not be directly examined, but images of the holotype taken by Dr. Tang Pu (ZUH) were used to compare with the new species described in this paper.
