尾突角蟾Megophryscaudoprocta(两栖纲,角蟾科)的进一步记述

尾突角蟾(Megophrys caudoprocta Shen,1994)具有非常特殊的特征,它们的尾杆骨(urostyle)长,超过坐骨(ischium)后缘,支持着尾突(caudal projection)；泄殖孔(cloacal pore)在股间后缘向腹面开口；上眼睑(upper eyelid)前部大,有一三角形突起向侧后突出.这些特征有别于角蟾属其他物种,有重要研究价值.近年来在模式标本产地又采到1雌2雄,先后共4号成体标本,本文对其形态特征,生物学资料和分布作了进一步记述,并拍摄到原色生态照片.

Additional Record of Megophrys caudoprocta (Amphibia, Megophryidae)

Megophrys caudoprocta Shen,1994 has several unique characteristics. Its urostyle is longer beyond the back fringe of ischium to support its caudal projection. The cloacal pore between the two posterior margins opens to the ventral. The anterior part of the upper eyelids is larger than posterior part and has a triangolar projection pointed posterolaterally. All these unique characteristics are different from any other congeneric species. Recently, three specimens including one female and two male were collected in Type locality. Here reported are the morphology, biological information and its distribution based on the further investigation on the Topospecimens.
