摘　　要：本文对雌性瑶山肥螈(Pachytriton inexpectatus)的泄殖腔进行了组织学研究,其具有和其他有尾两栖类相似的皮肤形态。虽然不同部位皮肤组织的厚度存在一定差异,但都具有表皮和真皮等相同的基本结构。雌性瑶山肥螈的泄殖腔还具有与精子储藏相关的特殊腺体储精管腺和腹腺,及与腺体结构相关的泄殖腔管。这表明该物种雌性个体的泄殖腔具备了精子储藏功能的形态结构,为其进行多次交配、分批产卵提供了基础。In this study, we conducted histological observation on the cloacae of two female Yaoshan Stout Newt, Pachytriton inexpectatus, which were collected from Maoershan, Guangxi in May of 2009. It was found that the cloacae possessed numerous sperm storage-related glands, spermathecae and ventral gland in the roof of the cloacae（Fig. 1）, suggesting that the cloacae of salamanders have the morphological structures which are related to the function of sperm storage. According to the experimental results, we speculate that the female Yaoshan stout newt may mate and lay eggs more than once.
