ResumoSUMMARYCyrtodactylus consobrinus and C. pubisulcus collected from Sarawak, Malaysia, were karyotyped. These species showed distinct intrageneric differentiation in the diploid chromosome number (2n = 48 and 42, respectively). Chromosomal variation was also recognized within C. pubisulcus: animals collected from the eastern part of Sarawak had a pair of subtelocentric chromosomes among telocentric elements. Specimens from the western part lacked the subtelocentric pair, but had a pair of metacentric chromosomes. Furthermore, heteromorphic sex chromosomes (ZW type) were observed in the latter karyotype. Taxonomic and evolutionary implications of the present findings are discussed.
