Male: Unknown.
Distribution. India (Kerala).
Host. Psalis pennatula Fab. (Lepidoptera: Erebidae).
Etymology. The specific name pennatulae comes from the species name of the host P. pennatula Fab.
Variation. Number of carinae dividing the scutellar lunules varies from six–seven.
Discussion. This new species is closely related to M. narendrani sp. nov. in having the scutellar lunules wide medially, propodeum coarsely rugose with a distinct transverse carina, and 1-CU 1 0.2× as long as 2-CU 1. It differs in the following characters, second flagellomere 2.7× as long as wide (second flagellomere 2.4× as long as wide in M. narendrani sp. nov.), terminal flagellomere 3.3× as long as wide (in M. narendrani sp. nov. terminal flagellomere 3.9× as long as wide), scutellar lunules divided by six–seven carinae (in M. narendrani sp. nov. scutellar lunules divided by eight–nine carinae), hind tibia 6.6× as long as wide (in M. narendrani sp. nov. hind tibia 4× as long as wide), metasoma black (metasoma orange brown in M. narendrani sp. nov.), and the pterostigma 2.6× as long as wide (in M. narendrani sp. nov. pterostigma 2.4× as long as wide). This new species is also related to M. carinicollis in having the propodeum coarsely rugose with a distinct medial longitudinal carina, scutellum rugulose and T1 with medial longitudinal groove. It differs in the following characters, face 1.4× as wide as long (in M. carinicollis face 1.6× as wide as long), frons smooth and strigose (in M. carinicollis frons rugulose), POL 1.9× OOL (POL 1.7× OOL in M. carinicollis), body black (body reddish in M. carinicollis), first and second flagellomeres 2.8, 2.7× as long as wide (in M. carinicollis first and second flagellomere 3.4, 3.1× as long as wide).
