The karyotypes of Sinotaia quadrata using air-drying method collected from Hyogal-ri, Pungyang-myeon, Yecheon-gun, Gyeongbuk, Korea were investigated. The diploid number of chromosomes is 2n=16. The eight chromosome pairs were identified and classified into three groups. The diploid cell has 1 pair of metacentric, 5 pairs of submetacentric and 2 pairs of subtelocentric chromosomes. Observed chromosomes ranged from 3.10 to 4.90 μm and the total length was 34.12 μm. The karyotype of S. quadrata is described for the first time.
