| 摘 要： | 以脾，肠细胞制作染色体标本，研究了细痣疣螈的染色体组型，结果表明该种体细胞染色体数为２ｎ＝２４第６，８对是亚中部着丝粒染色体，第１２对亚端部着丝粒染色体，其余９对无为中部着丝粒染色体。未发现异形染色体对。本文还对该种与其近缘种进行了核型比较，并对其分类地位进行了初步探讨。

| Abstract: | The karyotype of Tylolotriton asperrimus was studied by means of direct preparation of spleen, gut cells. The results showed that the diploid number, 2n, is 24, including 9 pairs of metacentric chromosomes, 2 pairs of submetacentric ones(Nos.6,8)and 1 pair subtelocentric ones (No. 12). No heteromophic chromosomes were found. And the similarities between T. asperrimus and T. verrucosus, T. kweichowensis, E. andersom were discussed. |
