摘　　要：20 0 4年 1月在海南省进行了两栖爬行动物调查 ,共获得 2 0种和l新种。在吊罗山采到小树蛙成体 ,与眼斑小树蛙P .ocellatusLiuandHu的体形、体色、鼓膜等特征相近 ,但有以下主要区别 :胫跗关节前伸超过吻端 ,额部有 2～ 3个银白色小斑点 ,背中部有一极明显的浅棕色椭圆形斑 ,腹面黄白色 ,前臂背侧具有 2～ 3条横纹 ,故将该蛙定为新种。In January,2004,a herpetological exploration was carried out in Hainan Province.20 species and 1 new species belonging to 12 genera,8 families and 2 orders were collected.After detail examination and comparison with closely related species,a small treefrog was recognized as a new form to science.The new form is described in Chinese text and an English diagnosis is given below.Philautus hainanus Liu and Wu,sp.nov.Holotype SCUM 041017,adult male;type locality:Mt.Diaoluo,Hainan Province,China;altitude 710 m,16 Jan.2004.Paratype SCUM 041081,adult male;collected from the same locality and date as the holotype.Diagnosis This new species is similar to Philautus ocellatus Liu and Hu in size and color,but differs from the latter in the following respects:1)tibiotarsal articulation over the tip of snout,while Philautus ocellatus reaching only beyond the anterior comer of the eye or between the eye and snout;2)2～3 dark cross-bands on back of lower arm,only one in the latter;3)beige ellipse speckle on the middle part of the body back in life,no beige ellipse speckle in the latter;4)yellow-white on abdomen,while lilac on abdomen and light green on the middle part in the latter.In comparison with P.hazelae Taylor,the body and finger discs of the new species are smaller in size,and it has no tubercle at the distal part of the tibia.In comparison with P.parvulus(Boulenger),tympanum of the new species is very distinct,its legs are longer and tibiotarsal articulation over the tip of snout.The type specimens of Philautus hainanus are preserved in the Zoological Museum of the School of Life Science,Sichuan University,Chengdu,Sichuan Province,China.Etyomology:The new species is named in honor of Professor Zhao Er-mi for his studing on Chinese amphibians andreptiles and tireless in helping young herpetologists of China.
