Distribution. India (Kerala).

Host. Psalis pennatula Fab.  ( Lepidoptera  : Erebidae  ).

Etymology. Microplitis narendrani  is named in honor of late Dr T.C. Narendran, Kerala, India, in recognition of his four decades of extraordinary work on parasitic Hymenoptera  .

Variation. Number of carinae dividing the scutellar lunules varies from eight –nine.

Discussion. This new species is closely related to M. carinicollis  in its large body size, T 1 sub-parallel sided, with medial longitudinal groove. It differs in the following characters, mesoscutum with medial furrow (mesoscutum without medial furrow in M. carinicollis  ), scutellum rugose (in M. carinicollis  scutellum rugulose) and presence of a longitudinal carina between antennal sockets (in M. carinicollis  longitudinal carina absent). This species is also related to M. pennatulae  sp. nov. in having the mesosoma 1.3 × as long as high, T 1 1.7 × as long as wide, presence of longitudinal carina between antennal sockets and T 2 with distinct median field. It differs in the following characters, mesoscutum with medial furrow (in M. pennatulae  sp. nov. medial furrow on mesoscutum indistinct), lateral temples hidden behind eyes in anterior view (in M. pennatulae  sp. nov. lateral temples slightly visible in anterior view), length of malar space 1.2 × basal width of mandible (in M. pennatulae  sp. nov. malar space 1.9 × basal width of mandible), scutellar lunules divided by eight –nine carinae (in M. pennatulae  sp. nov. scutellar lunules divided by six –seven carinae).
