记述采自海南省尖峰岭国家级自然保护区、取食危害竹子的额垠叶蝉属( Mukaria Distant)1新种:海南额垠叶蝉( M. hainanensis Yao, Yang & Chen, sp. nov.)。新种与危害慈竹的白斑额垠叶蝉( M. ablinotata Cai & Ge, 1996)相似,但新种的前翅为黄褐色;雄虫尾节侧瓣腹面突起长而波曲,腹面观其端部明显外弯;阳茎基部中央分叉处无突起,亚端部内侧突起粗而直。文中详细描记了新种的外部形态特征,编制了额垠叶蝉属中国种类检索表,绘制了雄性外生殖器特征图,提供了新种的生态照片,以及新种和近缘种白斑额垠叶蝉的整体与局部特征照片。新种模式标本保存于贵州大学昆虫研究所。

A New Bambusa chungii Feeding Species of the Genus Mukaria Distant(Hemiptera: Cicadellidae: Deltocephalinae: Mukariini) from China

A new bamboo-feeding species of the genus Mukaria Distant (Hemiptera: Cicadellidae: Deltocephalinae: Mukariini), M. hainanensis sp. nov., is described and illustrated. The new species was collected on bamboo( Bambusa chungii )from Jiangfengling National Natural Reserve, Hainan Province, China. The new species is closely related to M. ablinotata Cai & Ge, 1996, but can be distinguished by the characters below: forewing yellowish brown;ventral process of male pygofer long and sinuate, turning outside apically at ventral view;male aedeagus without process between two shafts, inside process of shaft near apex stout and straight. In this paper,the external morphological characteristics of the new species are described in detail. A key to Chinese species of the genus Mukaria is compiled, and the photograph illustrations of the new species and M. ablinotata, colour photographs of new species and its host plants are provided. The type specimens of the new species are deposited in the Institute of Entomology, Guizhou University, Guiyang, China.
