摘要 Nine species of the leafhopper genus Placidus Distant have been found in the world up to now, of which 4 new species are described from South China in this paper: P. dentatus, sp. nov. from Sichuan Province, P. striolatus, sp. nov. and P. nigrocupuliferous, sp. nov. from Yunnan Province, and P. flosifrontus, sp. nov. from Hunan Province. A key to all the 9 species of this genus is proposed. The type specimens are deposited in the Entomological Museum, Northwest Sci Tech University of Agriculture and Forestry, Yangling, Shaanxi, except the type specimens of P. dentatus and P. striolatus spp. nov. kept in the Institute of Zoology, Chinese Academy of Sciences in Beijing (IZAS). 记述世界小头叶蝉属PlacidusDistant昆虫 9种 ,其中包括 4个新种。条痕小头叶蝉Placidusstriolatus,sp .nov .和乌樽小头叶蝉Placidusnigrocupuliferou ,sp .nov .分布于云省 ,花顶小头叶蝉Placidusflosifrontus,sp .nov .分布于湖南省 ,密齿小头叶蝉Placidusdentatus ,sp .nov .分布于四川省。文中列出了所有 9种小头叶蝉的名录并编制了分钟检索表。新种模式标本分别保存于西北农林科技大学昆虫博物馆和中国科学院动物研究所 (IZAS)。新种模式标本和示差鉴别特征如下 :条痕小头叶蝉Placidusstriolatus ,新种 ,正模 :♂ (IZAS) ,云南省 ,大围山 ,135 0m ,195 6 Ⅴ 2 2 ,邦浦洛夫采。该新种与P .horneiDistant相近 ,但其雄性生殖瓣侧面观近三角形 ,尾节侧瓣向后渐狭 ,阳茎端部近 1 3处具数条长印痕 ,阳茎端部腹缘锯齿状 ,可以与后者相区别。花顶小头叶蝉Placi dusflosifrontus,新种 (图 3) ,正模 :♂ ,南非 ,郴州莽山 ,1985 Ⅶ 31,张雅林、柴勇辉采。该新种与P .horneiDistant相近 ,但其阳茎基部两侧所具的一对长的带状突不同于小头叶蝉属Placidus所有其他种类。密齿小头叶蝉Placidusdentatus,新种 (图 4 ) ,正模 :♂ (IZAS) ,四川省 ,马尔康 ,196 1 Ⅵ 9,李贵富采。该新种与P .brunneusKuoh相近 ,?
