【摘要】 观察和比较了四川峨眉山、洪雅瓦屋山、昭觉与湖北利川等四地区原鉴定为杜氏泛树蛙Ｐｏｌｙｐｅｄａｔｅｓｄｕｇｒｉｔｅｉ的核型。结果表明，事实上显示了两种极易区别的核型。昭觉和利川两地者一致相同属于同一种，它不但区别于杜氏泛树蛙，也区别于同属的任何一种。基于核型的显著差异，它应是一个新的超种Ｓｕｐｅｒｓｐｅｃｉｅ。作者将其命名为昭觉泛树蛙Ｐｏｌｙｐｅ－ｄａｔｅｓｚｈａｏｊｕｅｎｓｉｓ，并指定１９９３年７月２日采于四川昭觉七里坝的６８８３￣＃雄性成体为模式标本。更多还原

【Abstract】 Abstract The karyotypes,C-bands and NORs of 4 populations(Mt.Emei ,Mt. Washan andZhaojue of Sichuan Province and Lichuan of Hubei Province)of Polypedates dugritei,were observed and compared.The result revealed there were two distinct karyotypes in 4population of same species. The karyotypes of population from Lichuan and Zhao加ewere the same. It not only differs from P. dugritei from Mt. Emei but also any otherspecies in the genus.The authors suggested it be a new species in view of its distinct karyotypic charac-teristics and named it as Polypedates zhaojuensis. The adult male No. 6883 collected atZhao jue of Sichuan in July 2, 1993 is assigned as the type specimen.This paper reports a new superspecies of Anura found in China for the first time.Both karyotypes of P. zhaojuensis sp.nov. and P. dugritei have the same doploidnumber,26 with 5 large and 8 small pairs of chromosome. The zhaojuensis has a conspic-uous secondary constriction on the middle at long arm of No. 10 chromosome associatedjust with the C-banding and NORs. But the P. dugrilei has a satellite on the terminalof long arm of No。 10 chromosome associate just with the C-banding and NORs.更多还原
