Material examined. 1 ♀ India, Kerala, Kollam, Kundara, N 08° 57 ’ 03.1” N 76 ° 41 ’ 21.8 ”, 24.i. 2013. sweep net, coll. Ranjith ( DZUC).

Female. Body length 1.9 mm (based on examined specimen).

Head: Subcircular, 1.1 × as wide as long in anterior view (Fig. 20 -B); lateral temples slightly visible in anterior view; width of face (at widest) 0.5 × width of head; face 1.3 × as wide as long, slightly convex, rugose-punctate, sparsely setose (Fig. 20 -B); lateral temples, vertex and dorsal occiput slightly rugose; occiput concave; frons slightly rugose, anterior frons with raised area in dorsal view; area between antennal sockets without distinct carinate longitudinal ridge; eyes setose; POL 1.1 × OOL; ocelli forming an obtuse angle; antennae 1.1 × as long as body (Fig. 20 -A); first flagellomere 1 × as long as second flagellomere, 3 × as long as wide; second flagellomere 3.1 × as long as wide; terminal flagellomere acute, 3.2 × as long as wide.

Mesosoma: Mesosoma 1.1 × as long as high; mesoscutum rugose, setose, separated by a longitudinal ridge (Fig. 20 -C); notauli impressed, percurrent, meeting posteriorly; medial furrow present; scutellar lunules wide, divided by six carinae (Fig. 20 -C); area lateral to scutellar lunules convex; dorsal scutellum convex, sparsely punctate, setose with marginal crenulate groove laterally; propodeum rugose with percurrent medial longitudinal carina with lateral transverse carina (Fig. 20 -D); lateral pronotum with impressed furrow, slightly crenulate; mesopleuron 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 slightly rugose-punctate, setose; hind femur 4.1 × as long as wide; hind tibia 6.2 × as long as wide; outer hind tibial spur 0.4 × as long as basitarsus.

Wings: Fore wing 3 × as long as wide (Fig. 20 -F); pterostigma 2.8 × as long as wide (Fig. 20 -F); 1 -M slightly arched throughout; areolet quadrangular (Fig. 20 -F); margin of vannal lobe convex, setose.

Metasoma: T 1 1.25 × as long as wide, rugose, without medial depression, parallel sided, sparsely setose with apical swelling (Fig. 20 -D & E); T 2 with median field (Fig. 20 -E); T 2 –T 7 smooth with sparse transverse row of setae posteriorly and scattered setae postero-laterally (Fig. 20 -E); ovipositor 0.5 × as long as hind basitarsus.

Male: Same as female except scutellar lunules divided by four carinae, hind femur much darker than that of female.

Colour: Head, antennae, mesosoma and coxae black, tegulae dark brown, fore and mid legs mostly yellow brown, hind femur either completely reddish brown or along with yellow brown patches in postero-lateral sides ( Fig. 19 View FIGURE 19 -A & B), tibia with median half white, apical 1 / 3 and base with black infuscation (Fig. 20 -BF), tarsi dark reddish brown, wings infuscate (Fig. 20 -F), venation brown, pterostigma and veins uniformly dark brown, T 1 black with anterior laterotergites pale testaceous to white.

Distribution. India (Bihar, Karnataka and Kerala).

Host. Spodoptera mauritia (Boisduval)   .

Discussion. This species is close to M. prodeniae   in having the T 1 rugose, propodeum with distinct medial longitudinal carina. It differs from M. prodeniae   in the following characters: scutellum micropunctured (in M. prodeniae   scutellum rugose), T 1 without medial longitudinal groove (in M. prodeniae   T 1 with medial longitudinal groove), T 2 without setae medially (in M. prodeniae   T 2 with single row of setae medially), mesoscutum rugose (in M. prodeniae   mesoscutum rugose-punctate).

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