Abstract
The pompilina complex of the genus Tenthredo Linnaeus is solved which is now represented by eighteen species. Of these twelve species, namely, infucubitus, fuscoventris, breviantennata, dif, ifa, foveolata, fuscotibiae, breviantennata, equitarsus, picfa, acclivata and kulwantae added new to science from India are described and illustrated on a uniform systematic pattern. Following this pattern the already known species viz. frontatus Malaise, pseudofrontatus Singh & Saini, dalhousiensis Singh et al., santokhi Singh & Saini, serraflata Singh et al. and pompilina Malaise, are redescribed and illustrated. The taxonomic validity of these species has been supported by taxonomic description, illustrations, ecological affinities and detailed discussion. The male counter part of T. dalhousiensis Singh et al. whereas the female counter part of T. santokhi Singh & Saini are associated with their respective opposite sexes. A key to the species of the pompilina complex of the genus Tenthredo Linnaeus is provided.
