摘　　要：对世界蟾蜍科动物的分类现状做了概述 ,并对我国原定名为鳞皮游蟾NectophrynescalptusLiuandHu(1973)及叶昌媛等 (1978)将其改为鳞皮厚蹼蟾Pelophrynescalptus (Frost,1985订正种名为scalpta)的海南标本做了进一步研究 ,与现有蟾蜍科各属、特别是与东南亚地区的几个特有属的特征做了对比研究。结果表明 :原定名为鳞皮游蟾Nectophrynescalptus的海南标本应代表一个新属即小蟾属Parapelophrynegen .nov .,因此原定名为鳞皮游蟾 (或鳞皮厚蹼蟾 )的标本为新属的成员 ,即种名应改为鳞皮小蟾Parapelophrynescalpta (LiuandHu)。Parapelophryne gen. nov.
