Abstract: The four species of Rhinolophus are R. rouxi sinicus, R. affinis, R. pearsoni chinensis and R. cornutus pumilus in this paper, their karyotypes were examined and described by means of bone marrow cell.The number of diploid chromosomes is 42 in R. pearsoni chinensis, which is composed of 10 pairs of metacentrics, 2 pairs of submetacentrics, 8 pairs of telocentrics. There is a medium submetacentrics X and a very small telocentric Y chromosome in its sex chromosomes.The number of diploid chromosomes is 36 in R. rouxi sinicus, which is composed of 11 pairs of metacentrics, 3 pairs of submetacentrics, 3 pairs telocentrics. There is a medium metacentic X and a small subtelocentric Y chromosome in its sex chromosomes.The number of diploid chromosomes is 62 in R. affinis, which is composed of 60 telocentrics. There is a large submetacentric X and a small subtelocentric Y chromosome in its sex chromosomes. There exists a small satellite on the short arm of the chromosome No. 13.The number of diploid chromosomes are 62 in R. cornutus pumilus,which is composed of 60 teolcentrics. There is a large submetacentric X and a subtelocentric Y chromosome in its sex chromosomes. There exists a small satellite on the short arm of the chromosome No. 14.
