Chromosomes with detailed karyotypic information (nature, number, size, relative length, length of X-chromosome, nature of X-chromosome) and C-banding patterns of few species of grasshoppers belonging to sub-familiy Tryxalinae are discussed. The karyotypes comprises of acrocentric chromosomes with complement number 2n = 23 (male). Constitutive heterochromatin distribution was found at centomeric, interstitial, terminal sites along with thick and thin bands among all the species except in Acrida turrita which possessed only centromeric C-bands. The number and location of C-bands in Acridids exhibit intra specific variations. In the present communication the karyotypic analysis and C-banding patterns are analyzed for further differences between genera belonging to the same sub-family.
Key words: Acrididae, orthoptera, C-banding.
