Abstract
Six new species of Trichogrammen namely, T. hesperidis, T. agriae, T. pallidiventris, T. plasseyensis, T. poliae and T. raol, from India are described. Their similarity to other Indian or exotic species is discussed. A key to all known Indian species is presented. Crossing experiments between the new species and those resembling them most closely are summarized to show their limited genetic compatibility or incompatibility as the case may be.
