Chromosomal Studies of Eight Species of Bradybaenidae in Korea

한국산 달팽이과 (Bradybaenidae) 8종의 염색채 연구

The number of chronosomes and karyotypes in eight species of the family Bradybaenidae were analyzed by air-drying method using gonad. The mitotic haploid chromosome numbers of Acusta despecta sieboldiana were 29 and conisisted of 12 pairs metacentric, 17 pairs submetacentric chromosomes. The mitotic haploid chromosomes were 29 and 11 pairs metacentric and 17 pairs submetacentric and 1 pair telocentric chromosomes in Koreanohadra kurodana; 29 and 10 pairs metacentric chromosomes in K. koreana' 29 and 10 pairs metacentric and 18 pairs submetacentric, and 1 pair acrocentric chromosomes in Karaftohelix adamsi; 28and 10 pairs metacentric, and 18 pairs submetacintric chromosomes in Aegista chosenica; 28 and 14 pairs metacentric and 14 pairs submetacentric chromosomes in A.(Plectotropis) diversa; 28 and 15 pairs metacentric, 10 pairs submetacentric and 3 pairs acrocentric chromosomes in A. (p.)quelpartinsis; 29 and 12 pairs metacentric and 9 pairs submetacentric and 2 pairs telocentric chromosomes in Nesiohelix samarangae.
