河南两栖动物资源现状与区系分析

Current Status and Fauna of Amphibian in Henan Province

通过对野外调查所获标本的查询鉴定,并结合已有的文献报道进行整理,结果表明,河南省现生两栖动物计有2目10科30种,其中有尾目3科8种;无尾目7科22种.在30种两栖动物中,包括东洋种20种,广布种6种,古北种4种,分别占总种数的67%,20%和13%,以东洋种占优势,但也体现出古北界与东洋界相过渡的特点.动物地理区划分析表明,河南省两栖动物的物种多样性呈现出山区高、丘陵及平原低,豫南高于豫北,豫西高于豫东的特点.基于最新的研究报道,原记载的秦巴拟小鲵Pseudohynobius tsinpaensis、巫山北鲵Ranodon shihi应归为巴鲵Liua属;原记载的隆肛蛙Rana quadrana现分别被记为太行隆肛蛙Feirana taihangnicus、叶氏肛刺蛙Yerana yei;肥螈属Pachytriton的费氏肥螈Pachytriton feii在河南鲜有知晓者,应与其被描述、记载较晚有关.文中还讨论了豫南小鲵Hynobious yunanicus和湖北侧褶蛙Palophylax hubeiensis的物种有效性.

By the compilation of the relevant literature,field work and specimen identification,up to date of March2015,it sums up that the current situation of amphibian resources in Henan province is as follow：There are 30 species of amphibian in Henan province,belonging to 2orders,10 families,among which 8species in 3families are Urodela,and 22 species in 7families are Anura.20 out of 30 species are distributed in the Oriental realm,while 4in the Palaearctic realm and 6are widely distributed,accounting for 67%,13% and 20% of the total,respectively.Amphibian fauna in Henan is dominated by species of Oriental realm,while it also shows transectional traits between Oriental and Palaearctic realm.The geographical distribution analysis shows that the biodiversity of amphibian is higher in mountainous areas than the hills and plains,southern area is higher than northern area,and west is higher than the east.We discussed the discrepancy and possible name alteration of certain species referencing the relevant literatures.The following species would under the radar：the record validity of Hynobious yunanicus and Palophylax hubeiensis;Pseudohynobius tsinpaensis and Ranodon shihi should be relocated to Liua;the Rana quadrana should be documented as Feirana taihangnicus and Yerana yei respectively;Pachytriton feii which wasunknown to many was possibly due to its recently recording and describing.
