Male germ cell chromosomes of Burmagomphus divaricatus, Burmagomphus pyramidalis andBurmagomphus sivalikensis of family Gomphidae have been investigated by using conventional staining, C-banding,silver nitrate staining and sequence specific staining. The species were collected from Punjab and HimachalPradesh, India. All the species possess the chromosome number 2n = 23 which is the type number of the family.Terminal C bands and NOR’s are present at the autosomal bivalents and X chromosome is C positive and NOR rich inall the three species, while m bivalents show variation in distribution of C- heterochromatin and NOR’s. In thesequence specific staining, whole complement shows bright DAPI signals in B. divaricatus, bright CMA3 signals in B.pyramidalis and both DAPI and CMA3 signals in B. sivalikensis.
