摘　　要：本文讨论了掌突蟾属名Leptolalax和Carpophrys的有效性,认为Leptolalax应为有效属名。同时对中国福建、浙江、广西、湖南、贵州、云南等地的L.pelodytoides标本进行了分类研究,结果表明:前五个地区的标本应改订为新种福建掌突蟾L.liui;云南勐养标本仍保留为L.pelodyto-ides此外,峨山掌突蟾L.oshanensis特征明显,不应作为L.pelodytoides的亚种,应保留为种级;文后简述了新种L.liui的主要特征和生态习性资料。This paper deals with the validity of two generic names of the pelobatid toads, Carpophrys (Sichuan Institute of Biology, 1974, and 1977) and Leptolalax (Dubois, 1980). The latter is considered to be a valid genus. The specimens so far recorded as L. pelodytoides from Fujian, Zhe-jiang, Guangxi, Hunan, Guizhou and Yunnan, etc. were studied based on their external morphology of the adults and tadpoles, and adult skeletons and the result shows; 1) the specimens of L. pelodytoides from the former five areas should be regarded as Leptolalax Hut sp. nov.; 2) the specimems of Leptolalax from Mengyang, Yunnan should still be remained in L. pelodytoides; 3) the diagnostic characters of L. oshanensis are distinct, therefore the name should be maintained at the species level.The diagnosis of the new toad is given below:Leptolalax liui Fei et Ye, sp. nov. Holotype: No. 6411563, adult male; type locality: Chong'an Country, Fujian(Fukien), altitude 800m; June 8, 1964.Allotype: No. 6411364 adult female; May 23, 1964 collected from the same locality of the holotype.Paratypes: 24♂♂,1♀ and tadpoles of different developmental stages collected from Chong'an May 23 to August 8, 1964, altitude 730-1100m; 7 ♂♂and tadpoles collected from Jianyang of Fujian, June 30 (o July 3, 1964, altitude 1000m; 4♂♂ collected from Dehua of Fujian, Aptil 21 to May 9, 1964, altitude 1400m.Diagnosis: the new species is closely related to L. pelodytoides, but is distiguished mainly by having: 1) smaller size (males 23-28.7, females 23.1-28.1 mm); 2) toes with rudimentary webs; 3) larger sphenethmoid extending beyond na als, and smaller ethmoid cartilage; 4) wider labial margin of tadpoles without additional papillae, and shorter and weaker labial teeth series, teeth formula usually 1:3-3/Ⅰ:2-2.The type specimens are kept in the Chengdu Institute of Biology, Academia Sinica.
