Abstract:A new species,Kosalya cetua Long & Chen sp.nov.of the planthopper genus Kosalya Distant,1906 (Hemiptera:Fulgoromorpha:Achilidae:Plectoderini) from Guangxi,China was described and illustrated.The new species resembles Kosalya curvaeanalis,but differs from the latter in:anal segment in dorsal view symmetrical (asymmetrical in the latter) and medioventral protrusion of pygofer in ventral view near lateroapical margin with a small protrusion(the latter without).And a key to all species of the genus was given.The type specimens of the new species are deposited in Institute of Entomology,Guizhou University,Guiyang,China.

栲颖蜡蝉属Kosalya Distant,1906隶属于半翅目Hemiptera蜡蝉总科Fulgoromorpha颖蜡蝉科Achilidae菲颖蜡蝉族Plectoderini,该属是Distant[1]于1906年以采自缅甸的黄线栲颖蜡蝉K.flavostrigata Distant,1906作为模式种而建立的,主要分布于东洋界和古北界[2]。1950年,Fennah[3]对该模式种作了进一步描述,Anufriev[4]也于1969年首次在俄罗斯发现并对该模式种雄性外生殖器进行了首次描述。1989年,Chen等[5]另记述中国台湾省的2新种,即膨大栲颖蜡蝉K.dilatata Chen,Yang & Wilson,1989和短突栲颖蜡蝉K.improcera Chen,Yang & Wilson,1989;1999年,周尧等[6]在我国福建省报道了膨大栲颖蜡蝉K.dilatata Chen,Yang & Wilson,1989;2005年,Emeljanov[7]在俄罗斯报道了该属的第四个新种 K.concludens Emeljanov,2005;2013年,Long等[2]又报道了中国栲颖蜡蝉属的3新种,即 环斑栲颖蜡蝉K.circumscripta Long & Chen,2013、曲肛栲颖蜡蝉K.curvusanusa Long & Chen,2013和单斑栲颖蜡蝉K.unimaculata Long & Chen,2013。作者在对贵州大学昆虫研究所颖蜡蝉科昆虫标本的进一步整理时发现采自我国广西花坪国家级自然保护区1新种,其所有模式标本均保存于贵州大学昆虫研究所,现对该新种报道如下。……
