  • 摘要: 贵州已知有原指树蛙属物种1种,即:海南原指树蛙。该文基于形态学和分子生物学证据将采自贵州省黔西南州清水河自然保护区的原指树蛙标本描述为一新种,命名为饶氏原指树蛙Kurixalus raoi sp. nov .。新种可通过以下形态特征与同属其它物种相区别:体型小,雄性体长28.2-32.2 mm,雌性38.6 mm;吻圆,吻端无皮肤突起;雄性具单咽下内声囊;背面灰褐色,散有细小疣粒;咽部黑褐色,皮肤呈颗粒状;胸部有一对左右对称的深色大斑;有犁骨齿;虹膜棕褐色;胫跗关节达眼球中部;婚垫弱;体侧皮肤粗糙;趾间具蹼,蹼式为I2‒2II1.5‒3III2‒3IV3‒2V。新种与仅分布于台湾的面天原指树蛙亲缘关系最近,两者之间在16S rRNA基因和COI基因上的遗传差异分别为2.9%和5.4%。
