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 T 1 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).
