务川臭蛙分布区域扩大及其濒危等级再评估

The Expansion of the Distribution of Odorrana wuchuanensis and the Reevaluation of Its Threatening Category

2013年9月在湖北省建始县采集到的2只务川臭蛙(Odorrana wuchuanensis)标本,为湖北省新纪录。该记录使务川臭蛙的分布区由大娄山脉东段,沿武陵山脉延展至湖北建始县。因此,建议将其濒危等级调低至濒危(endangered,EN)。与模式标本比较,建始县雌蛙标本头体长99.6 mm,远大于模式标本雌蛙的最大记录;成年雄蛙头体长62.8 mm,亦小于模式标本的最小记录;建始县雌蛙体侧背皮肤亦有淡色小刺粒,因此,该特征不属于第二性征。

Two specimens of Odorrana wuchuanensis,as new amphibian record in Hubei Province,were collected from Jianshi County,Hubei Province in September 2013. Extent of occurrence of O. wuchuanensis is extended from Eastern Mountains Dalou to Jianshi County,Hubei along the Mountains Wuling,Therefore,we suggest that its endangered category is assessed as endangered（ EN）. Compared with the type specimens,the snout-vent length of the female specimen from Jiangshi is significantly greater than the maximum record in type specimens; the snout-vent length of the male specimen from Jiangshi is significantly shorter than the minimum record in type specimens. Small pale spinous granule can not be considered as the secondary sexual characteristic because of its existence on dorsolateral skin of female specimen from Jianshi.
