摘　　要：据记载竹叶臭蛙Odorranaversabilis分布于广西、贵州、湖南、福建、浙江、安徽、广东、海南。作者对比研究了 7个省的 13个居群标本的形态特征 ,可分为 3个形态型 ,这 3个形态型标本的特征彼此差异明显 ,被确定为 3个不同的种 ,其中包括 2个新种 ,即小竹叶臭蛙O .exiliversabilissp .nov .和鸭嘴臭蛙O .nasutasp .nov .。为印证形态分类的结果 ,又采用形态数值性状标准差别分析和DNA指纹实验分析 ,其结果与形态特征分类研究结果一致。本文对 2个新种的形态和生物学资料进行了记述。Odorrana versabilis was reported distributing in Guangxi, Guizhou, Hunan, Jiangxi, Guangdong, Fujian, Zhejiang, Anhui and Hainan, China. Thirteen populations ocurring in seven provinces were studied by morphology, and divided them into three discrete morphotypes. Each of the three morphotypes is judged to represent a species, and two are described as new: Odorrana exiliversabilis sp. nov. and Odorrana nasuta sp. nov. Furthermore, morphometry and DNA fingerprinting were used to confirm the results of morphology, and identical viewes were got. Based on the results of above, the two new species and their biological data are described.1 Odorrana exiliversabilis sp. nov. (Fig.1)\; Holotype CIB64Ⅰ2013, an adult male, body length 46.1*!mm. Type locality: Huangkeng (117.63°E, 27.60°N), Jianyang Co. Fujian Prov., China. Altitude 1*!030*!m, 30 June 1964; by YANG Fu-Hua. Paratypes 5♂♂(CIB64Ⅰ2008_2009,2205,2208,2263),10♀♀(64Ⅰ2010_2012, 2134, 2206, 2207, 2209, 2298_2299, 2309),collected from the same locality with the holotype, on 5 June to 5 July 1964; 18♂♂(CIB64Ⅰ1553, 2318_2320,2543_2545, 2587, 276_2761,2764_2765,2775,3415_3417,4101,4155)、30♀♀(CIB64Ⅰ2316_2317,2342_2346,2583_2586, 2752_2759, 2762_2763, 2772_2774, 3418,3433, 3669_3670, 4031_4032)、1 juveniles (CIB64Ⅰ4102) and tadpoles collected from Chongan Co. (Sangang and Miaowan), Fujian Prov., 600_1*!100*!m, on 8 June to 14 Sep. 1964; 2♀♀(64Ⅱ0334,0335) from Daiyunshan, Dehua Co., Fujian Prov., 1*!525*!m; 21 Apr. 1964. Diagnosis. This new frog is similar to Odorrana versabilis (Liu and Hu), but differs from the latter by following characters: 1)smaller in size (body length 48.7±2.37*!mm, n=20, in male; 58.1±3.04*!mm, n=24, in female); 2)body length of female / body length of male = 1.19∶1.00; 3) head moderate wide and narrow, slightly longer than wide; 4) snout not shielded; 5) tip of snout bluntly rounded, not very projecting beyond lower jaw; 6) toes entirely webbed, range of webs narrow, free margin deeply concave;
