The cytogenetics of the stump-tailed macaque (Macaca arctoides) in Thailand was studied.Blood samples were collected from this species maintained in Nakhon Ratchasima Zoo and Songkhla Zoo.After apac1/60/1/cw standard whole blood lymphocytes were cultured in the presence of colchicine, metaphase cells were spreaded on the slide and air-aired.Chromosomes were observed using Conventional Giemsa staining under a light microscope.

The results show that the number of diploid chromosomes of the stump-tailed macaque is 2n=42, and the color touch 7/97 fundamental number (NF) are 84 chromosomes in the female and male.The types of autosomes are 6 large metacentric, 8 large submetacentric, 4 medium metacentric, 12 medium submetacentric, 8 small metacentric and 2 small submetacentric chromosomes.In addition, the pair of chromosome 13 is a clearly observable satellite chromosome.The X chromosome is medium submetacentric and the Y chromosome is the smallest submetacentric chromosome.
