摘要: 在贵州省龙里县水场乡采集到一批瘰螈标本，与瘰螈属已知物种比较后，确定其为一新种，即龙里瘰螈（Paramesotriton longliensis Li，Tian，Gu et Xiong sp. nov）。新种与尾斑瘰螈（Paramesotriton caudopunctatus）相似，但新种由于上鳃骨后端上翘，成体头部后端两侧鳃迹部位各有1个明显突起；体背嵴棱强烈隆起；指、趾两侧无缘膜，指、趾末端有黑色角质鞘；肛后尾的腹鳍褶橘红色，约在1/2处此颜色消失；雄螈尾后段浅紫红色无斑纹。统计并记述了新种的外形、头骨特征、染色体组型、生物学资料。Abstract: A new species of Paramesotriton longliensis sp.nov. (Holotype: No.0705015, adult male; Allotype: No.0705019, adult female; Paratypes: 10♂♂, 10♀♀) was discovered during a survey of herpetofauna in Shuichang village, Longli County, Guizhou Province between May 4 to May 12, 2007.
