Abstract
Five new species of genus Dichomeris Hübner, namely sicasymmetria, kalesarensis, hansi, fuscodelta and bispotalis along with an already known species i.e. rasilella (Herrich-Shaffer) are described and illustrated in detail. New species groups are also proposed for the five new species owing to their different set of morphological and genitalic features from already known fifteen groups. Separate keys to the species groups have also been formulated on the basis of different morphological attributes including external genitalia. Prevalence of intra-specific variations observed in wing venation and sicae of rasilella have been commented upon.

Key words:Gelechiidae, Dichomeris, new species groups, five new species, intra-specific variations, North India.
