对凹耳蛙模式标本产地的蛙类及蝌蚪进行了调查,并对蝌蚪进行了人工饲养和生长发育到完成变态的观察,结果发现一种没有腹吸盘的小型蝌蚪是凹耳蛙的蝌蚪.由此证明凹耳蛙不具有湍蛙型蝌蚪,应不属于湍蛙属蛙类.对凹耳蛙成体和蝌蚪特征的分析表明其与蛙亚科其他属及所辖种不同,建议另立新属.
A field investigation was conducted in the type locality of the sunken-ear frog Rana tormotus Wu 1977. 8 species of frogs and toads and 4 species of tadpoles were collected in the area. They are Megophrys boettgeri, Bufo gargarizans, Amolops wuyiensis, Paa spilosa, Rana limnocharis, Rana livida, and Rana schmackeri, as well as Rana tormotus. The tadpoles were reared in laboratory and observed carefully everyday. After carefully observation and comparison the froglets with known forms of tadpoles, the fist one is the tadpole of Amolops wuyiensis, the second is Paa spinosa and the third one belongs is Rana schmackeri. The last one was a smallest form (less than 30 mm in total length) and its froglet has the same morphological characters of Rana tormotus. It indfcates that Rana tormotus is not belong to Amolops. By comparison of Rana tormotus with Amolops, Pseudoamolops, Rana and Stauroi , Rana tormotus should be considered placing to a new genus.
