Abstract:The karyotypes of Paramesotriton longliensis and P. zhijinensis were studied with conventional smears. The results showed that, the karyotype of P. longliensis was 2n=24=16m+8sm, NF=48, in which the No.7, 10, 11, 12 were submetacentric chromosome (sm), while the others were metacentric chromosome (m); the karyotype of P. zhijinensis was 2n=24=20m+4sm, NF=48, in which No. 9, 11 were sm, while the others were m. The karyotype difference between P. longliensis and P. zhijinensis provideed new evidence to support the validity of the two species.
