Abstract

The karyotypic and cytogenetic characteristics of southern catfish, Glyptothorax silviae Coad, 1981, was investigated for the first time by examining metaphase chromosome spreads obtained from gill epithelial and kidney cells. The diploid chromosome number of this species was 2n = 52. The karyotype consisted of 9 pairs of metacentric, 14 pairs of submetacentric, and 3 pairs of subtelocentric chromosomes. The arm number was 98. No heteromorphic sex chromosomes were cytologically detected in this catfish. Comparison of the chromosome number of this fish with that of the other members of subfamily Glyptosterninae shows that 2n = 52 may be regarded as characteristic of the primitive karyotype in this subfamily.
