Key to Indian species of Parastephanellus

1. Vein 2-SR+M of fore wing absent ( Fig. 91 )....................... P. reductus Binoy, Girish Kumar & Santhosh sp. nov.

- Vein 2-SR+M of fore wing largely present ( Figs 72 , 80 )....................................................... 2

2. Pale streak of temple scarcely noticeable........................................................ P. scitus Elliott

- Pale streak of temple distinctly developed.................................................................. 3

3. Ovipositor sheath distinctly longer than body ( Fig. 72 ); mesoscutum without median longitudinal row of pits but with a median carina; metapleuron without a smooth area separating from propodeum; [vertex with several cross carinae and with a mediolongitudinal grove]........................................................ P. mufeedae Narendran & Sureshan

- Ovipositor sheath approx. as long as or distinctly shorter than body; mesoscutum with median longitudinal row of pits and no median carina; metapleuron with a smooth area separating it from propodeum..................................... 4

4. Ovipositor sheath subequal to length of body; vertex mostly smooth, two strong carinae followed by weak striae (medially indistinct); pronotum smooth................................................ P. malabaricus Narendran & Sheela
