ABSTRACT
The karyotype of Chelomus insularis (Hymenoptera, Braconidae, Cheloninae) is described. The males show an haploid number of fourteen chromosomes, confirming haplo-diploid sex determination. Comparisons of these results with karyotypes of other species of the same family were done and a possible mechanism involved in the karyotype evolution of this species is discussed.
