Standardized karyotype and idiogram of the pileated gibbon (Hylobates pileatus) Nakhon Ratchasima Zoo, Thailand was studied. Blood sample were taken from 2 females and 2 males. After standard whole blood lymphocyte culture at 37°C for 72 h in the presence of colchicine, the metaphase spreads were performed on microscopic slides and air-dried. G-banding and high-resolution technique were applied to stain the chromosomes. The results showed that the number of diploid chromosomes of pileated gibbon was 2n (diploid)=44. The type of autosomes were 30 metacentric, 10 submetacentric and 2 acrocentric chromosomes, with X and Y chromosome being submetacentric and acrocentric chromosome, respectively. From the G-banding and high-resolution technique, the numbers of bands and locations in the pileated gibbon were 183 and 236 respectively, each chromosome pair could be clearly differentiated.
