【摘要】 <正> 通过整理四川、贵州、湖北的锄足蟾科动物标本,发现有五个新种:四种齿蟾Oreolalax和一种齿突蟾(曾名为“短齿蟾”)Scutiger。其中两个齿蟾新种的蝌蚪(包括将完成变态的幼蟾)曾被描述发表过,为未定种名的“短齿蟾”蝌蚪(刘、胡,1960);现在已发现成体,并在本文内予以定种名。所有模式标本均保存于成都四川生物研究所。更多还原

【Abstract】 Five new pelobatid toads from Sichuan,Guizhou and Hubei are reported andtheir diagnoses are given below. The type specimens are kept in the Chengdu Institutd of Biology. Oreolalax liangbeiensis Liu et Fei,sp. nov. (plate Ⅰ, fig, 1; plate Ⅱ, fig. 5,6) Holotype: No. 65Ⅱ0345, adult male;type locality:Pu-xiong of Yuexi-Xian, Si-chuan,altitude 2950m; May 18, 1965; collected by Jiang Yao-ming and Fei Liang. Allotype: No, 65Ⅱ0160, adult female, collected from the same locality of the holo-type on May 11,1965. Paratypes: 6??,2??,tadpoles of different stages including metamorphosized in-dividuals from the same locality; from May to June. Diagnosis: This new species is closely related to Oreolalax major (Liu et Hu),but differs from the latter in:1) the ratio of the length of tibia to the body lengthbeing 45.7%, and the heels just meeting when the limbs are folded at right angle tothe body: 2) without any dark spots or marblings on ventrum; 3) labial teeth for-mula of the tadpole mostly Ⅰ:3-3/Ⅰ:4-4 or Ⅰ:4-4/1:4-4. Oreolalax puxiongensis Liu et Fei, sp. nov. (plate Ⅱ, fig.7, 8) Holotype: No.65Ⅱ0646,adult male; type locality: Pu-xiong of Yuexi-Xian,Sichuan, altitude 2900 m; June 19,1965; collected by Jiang Yao-ming and Fei Liang. Allotype: No. 65Ⅱ0716, adult female, collected with the holotype. Paratypes: 178??,12??, eggs and tadpoles of different stages from same loca-lity, altitude 2860-2900 m; May to June, 1965. 18?? from Ye-le of Mianning-Xian,Sichuan, altitude 2600-2900 m;June;18-27,1965. Diagnosis: This new species is closely:related to Oreolalax schmidti (Liu), butdiffers from the latter in: 1) many strongly developed black spiny ridges arrangedmore or less in longitudinal rows on the back of the males, while for the females lessdeveloped; 2) animal pole of the egg light purplish gray. Oreolalax lichuanensis Hu et Fei, sp. nov. (plate Ⅰ, fig. 2,; plate Ⅱ, fig. 4, 9,10) Holotype: No. 74Ⅰ0915, adult male; type locality: Han-chi of Lichuan-Xian, Hubei,altitude 1790m; July 3, 1974; collected by Jiang Yao-ming and Shen Yang. Allotype: No. 74Ⅰ0913, adult female, collected with the holotype. Paratypes: 1? and tadpoles of different stages from the same locality. Other collecting data of tadpoles: June, 1956 from Jin-fo-shan of Nanchuan-Xian, Sichuan, altitude 1799m; June 1959 from Weining-Xian, Guizhou, altitude2300m (Lin et Hu 1960 described as Scutiger tadpole from Weining). Diagnosis: It is a distinct new Oreolalax in having: 1) tympanum distinct; 2)tibiotarsal articulation reaching posterior corner of the eye; 3) many light yellowishspots on the throat, belly and ventral sides of the limbs; 4) tadpoles with a distinctarched light color marking located at dorso-posterior part of the body and also alonganterio-dorsal fin fold. Oreolalax rhodostigmatus Hu et Fei, sp.nov. (fig.1) Holotype: No. 71001, adult male; type locality: Zunyi-Xian, Guizhou, altitude1040m; February, 1971; collected by Deng Qi-xiang (specimen presented by Nan-chong Teaching College). Tadpoles of different stages including metamorphosizbd individuals collectedfrom different localities: 1) from Jin-fo-shan, Xian-mi-dong of Nanchuan-Xian, Si-chuan, altitude 1158m; from May to June, 1956; 2) from Long-dong of Bijie-Xian,Guizhou, altitude 1250m; May 1959 (Liu et Hu 1960 described as Scutiger tadpoles,one from Xian-mi-dong and one from Bijie); 3) from Han-chi of Lichuan-Xian,Hubei, altitude 1790-1830m; from June to July, 1974. Diagnosis: It is a distinct new Oreolalax in having: 1) two oblong elevated pal-mar tubercles arranged in "?" form; 2) about ten yellowish white small roundwarts on the side of the body; 3) a large orange-red round wart on each axilla, and asimilar one on posterior aspect of each thigh; 3) total length of the fully developedtadpoles about 110 mm, labial teeth formula Ⅰ:1-1, Ⅰ:8-8/Ⅰ:9-9 or Ⅰ:1-1, Ⅰ:7-7/Ⅰ:8-8. Scutiger tuberculatus Liu et Fei, sp. nov. (plate Ⅰ, fig. 3; plate Ⅱ, fig. 11,12) Holotype: No. 65Ⅱ0448, adult male; type locality: Pu-xiong of Yuexi-Xian, Si-chuan, altitude 3000m; May 31, 1965; collected by Jiang Yao-更多还原
