Male meiosis and karyotypes of 5 species of Indian Heteroptera (Megacopta cribraria of Plataspidae and Coridius ;anus, Andrallus spinidens, Nezara viridula and Gynenica affinis of Pentatomidae) are analysed. Diploid number of 2n = 12, XY inM. cribraria, 2n = 14, XY in C. ;anus, A. spinidens and N. viridula and 2n = 16, XY in G. affinis are recorded. During karyotypic evolution, mechanisms like minor interchromosomal changes in Plataspidae and fragmentation and interchromosomal changes in Pentatomidae are suggested to have operated.
