The karyotypes and meiotic behaviors of three Carbula species ( Carbula obtusangda Reuter, C. putoni (Jakovlev)and C. sinica Hsiao et Cheng) were studied. Karyotype analyses using specific software were made and model karyotype chart was presented. All three species have the typical diploid Chromosome number of 14 for the family Pentatomidae and X‐Y sex chromosomal mechanism, but the behavior of autosomes and sex‐chromosomes during meiosis among three species are different, and one or two supeeruumerary chromosomes were detected in C. putoni . These characteristics may provide some useful clues on the study of pentatomid taxonomy and phylogeny.
