Description.
Holotype, female. Body length 6.5 mm, fore wing length 4.0 mm.
Head. Head 1.5 × as wide as long in anterior view (Fig. 3 B View Figure 3 ) and 1.1 × as wide as long in dorsal view (Fig. 3 D View Figure 3 ); face flat, sparsely punctate, elevated anteriorly below antennal sockets, setose, 2.7 × as wide as long (Fig. 3 A, B, C, E View Figure 3 ); clypeus strongly transverse, smooth, lower margin weakly convex (Fig. 3 B, C View Figure 3 ); tentorial pits rounded (Fig. 3 B View Figure 3 ); malar space short, 0.5 × basal width of mandible; mandible broad with two teeth, upper tooth longer and wider than lower tooth (Fig. 3 B, C View Figure 3 ); vertex and temple strongly enlarged, temple 1.1 × as long as eye in dorsal view, sparsely punctate laterally, with sparse setae (Fig. 3 D, E View Figure 3 ); frons and vertex polished, sparsely punctate and setose (Fig. 3 D View Figure 3 ); eye glabrous (Fig. 3 View Figure 3 ); OOL: diameter of lateral ocellus: POL = 1.8: 1.0: 1.1; antenna with 14 flagellomeres; scape subcylindrical, pedicel bulb-shaped (Fig. 3 A, E View Figure 3 ); medial flagellomeres distinctly transverse (Fig. 3 A, E View Figure 3 ); first flagellomere 1.5 × as long as second flagellomere and 1.3 × as long as wide; second flagellomere 0.9 × as long as wide.
Mesosoma. Mesosoma elongate, 2.8 × as long as high (Figs 3 A View Figure 3 , 4 A View Figure 4 ); dorsal part of pronotum crenulated medially (Fig. 4 B View Figure 4 ), pronotum laterally smooth and polished, crenulated medially (Fig. 4 A View Figure 4 ); mesoscutum flat in lateral view (Fig. 4 A View Figure 4 ), smooth, setose only medially (Fig. 4 B View Figure 4 ); notaulus present anteriorly (Fig. 4 B View Figure 4 ); scuto-scutellar groove smooth without wrinkles (Fig. 4 B View Figure 4 ); scutellum smooth, setose laterally and posteriorly (Fig. 4 B View Figure 4 ); mesopleuron coriaceous, setose (Fig. 4 A View Figure 4 ); mesopleural furrow indistinct (Fig. 4 A View Figure 4 ); epicnemial carina present, joining with subtegular ridge (Fig. 4 A View Figure 4 ); metapleuron rugose with transverse wrinkles medially, sparsely setose (Fig. 4 A View Figure 4 ); propodeum punctate in anterior half, transversely striate-rugose in posterior half, combined area basalis + superomedia narrowed in anterior 0.3, with irregular transverse wrinkles, costula absent, posterior transverse carina present; pleural carina complete (Fig. 4 C View Figure 4 ).
Legs. Femora robust (Fig. 1 A View Figure 1 ); hind coxa smooth (Fig. 4 D View Figure 4 ); hind femur 2.9 × as long as wide (Fig. 4 A, D View Figure 4 ); hind tibia 3.3 × as long as wide; hind basitarsus 4.7 × as long as wide (Fig. 4 D View Figure 4 ).
Wings. Wings hyaline (Fig. 4 F View Figure 4 ); pterostigma 3.2 × as long as wide; fore wing vein 2 r & RS joining to pterostigma before its middle, 2.3 × as long as 2 rs-m (Fig. 4 F View Figure 4 ); vein 2 rs-m 1.7 × as long as M between 2 rs-m and 2 m-cu; vein 1 cu-a distinctly postfurcal (Fig. 4 F View Figure 4 ); hind wing vein with nervellus (CU) intercepted in middle.
Metasoma. First metasomal tergite strongly convex in lateral view (Fig. 4 D View Figure 4 ), sparsely punctate, setose with pair of weak dorsal carinae, twice as long as its maximum width; spiracle situated at middle of tergite (Fig. 4 D – F View Figure 4 ); second tergite polished with distinct thyridium, sparsely punctate, setose, 1.1 × as long as wide (Fig. 4 E, F View Figure 4 ); third tergite polished, as long as wide (Fig. 4 E, F View Figure 4 ); tergites 4–7 polished, scarcely setose laterally; hypopygium straight posteriorly; ovipositor hardly exposed; sheath setose, 0.2 × as long as hind tibia (Fig. 4 D, E View Figure 4 ).
Colour. Body predominantly black; antenna, mandible, tegula, fore leg (excluding tibia and tarsus), hind leg (except tarsus) and tergites 3–7 reddish brown; flagellomeres 1–4, fore tibia and tarsus, mid leg, hind tarsus, posterior margin of hypopygium and ovipositor sheath yellow.
Male. Unknown.
Distribution.
Thailand.
Etymology.
The new species is named after the distinctly depressed body.
Comparative diagnosis.
The new species is similar to M. tibialis , but differs from this species by antenna as long as mesosoma length (1.4 × as long as mesosoma in M. tibialis ), first flagellomere longer than second flagellomere (as long as second flagellomere in M. tibialis ), temple 1.1 × as long as eye in dorsal view, hind tibia not swollen, not wider than hind femur (hind tibia strongly swollen, 1.1 × as wide as hind femur in M. tibialis ), distinct thyridium (lacking in M. tibialis ).
