摘要
报道了采自河南省内乡县的一种小鲵科标本,经形态学鉴定以及DNA序列比对,确定为秦巴拟小鲵(Pseudohynobius tsinpaensis)。内乡是该物种已知分布区的东限,与已知分布点相差3个经度,呈间断分布。秦巴拟小鲵在内乡的发现可为探讨小鲵科动物的起源和演化提供重要的动物地理学依据。
5 adult females,3 adult males, 17 subadults, 1 pair of egg-case and many larvae were collected in Neixiang County, Henan Province, in April, November, 2000 ; May 2001 ; July, August, Oct, 2002 ; August, 2003. They were identified as Pseudohynobius tsinpaensis with morphological and DNA sequencing analysis. The discovery of this species indicates that its distribution may be disjunctive, reaches East Hill and Plain Subregion from West Mountain and Plateau Subregion of Central China Region, with the easternmost boundary in Neixiang County. The result of this research will benefit to reveal the origination and evolution of Hynobiidae.
