Abstract: A new species of the genus Doryphorina , D. multifurcella Zheng & Chen sp. nov. from China is described and illustrated. Photographs are provided. A key is given to identify all the known species of Doryphorina . Specimens are deposited in the Institute of Entomology, Guizhou University, Guiyang, China (GUGC). This species is similar to D. conglobatus Zheng, Yang & Chen, but differed from the pallobase with 2 pairs of apical membranous lobes, dorsal apical lobes long and slender, with long spines both at base and apical, however, the latter has long and slender dorsal apical lobes, with 3 long spines at base in lateral view.

长头象蜡蝉属 Doryphorina 隶属于象蜡蝉科Dictyopharidae象蜡蝉亚科Dictyopharinae,系Melichar(1912)以苏门答腊岛的 D. stali Melichar, 1912为模式种建立。Fennah(1978)Song和Liang(2013)Zheng等(2014)先后对该属进行了修订和补充。现包含5种:长头象蜡蝉 D. stali Melichar, 1912(缅甸,马来西亚,印度尼西亚)、小长头象蜡蝉 D. minor Fennah, 1978(越南,中国:广西、海南、广东、贵州)、弯长头象蜡蝉 D. subdeflexa Fennah, 1978(越南,中国:云南)、团簇长头象蜡蝉 D. conglobatus Zheng & Chen, 2014(中国:陕西)和贵州长头象蜡蝉 D. guizhouensis Zheng & Chen, 2014(中国:贵州、海南)。作者在整理和检视贵州大学昆虫研究所馆藏标本时,发现该属一新种,并将其命名为多刺长头象蜡蝉 Doryphorina multifurcella sp. nov.。本文对该新种进行了记述,并提供该属的种级检索表。新种的模式标本保存在贵州大学昆虫研究所。
