Abstract
The species of the Ichneumonid genus Isotima Foerster occurring in Kerala is reviewed. Two new species viz., I. anupama sp. nov. and I. rakela sp. nov. are illustrated and described. Their affinities with their closest relatives are discussed. I. rufithorax (Szepligeti) is newly recorded from Kerala. The larvae of Hyblaea puera (Cramer) is a new host record for I. pusilla (Szepligeti). A key to the Oriental species of Isotima Foerster is also provided.
