A new leafhopper genus of the tribe Gyponini, Dutrapona gen. nov., is proposed and described based on males of three newly described species from Central and South America: Dutrapona tenuis sp. nov. (type species) from Alajuela, Costa Rica, Dutrapona reticulata sp. nov. from Napo, Ecuador, and Dutrapona zahniseri sp. nov. from Coclé, Panama. The new genus resembles genera of the Hecalapona complex in sharing characteristics such as: body yellow without maculae and dorsoventrally flattened, crown moderately produced with anterior margin rounded and projected over anterior margins of eye, crown-face transition distinct and thin, maxillary plates narrow and not extending to clypeus apex and forewing with narrow appendix. However, Dutrapona gen. nov. can be distinguished from other Gyponini genera by the combination of the following of characteristics: ocelli positioned closer to midline and posterior margin of the crown, crown-face transition spatulate with two well defined carinae, male sternite VIII longer than wide, male pygofer with a pair of small caudal denticulated processes, subgenital plates short, and aedeagus with a pair of basilateral elongate processes.
基于来自中美洲和南美洲的三个新描述物种的雄性个体,提出并描述了叶蝉族(Gyponini)的一个新属——杜特拉叶蝉属(Dutrapona gen. nov.):来自哥斯达黎加阿拉胡埃拉的细杜特拉叶蝉(Dutrapona tenuis sp. nov.,模式种)、来自厄瓜多尔纳波的网纹杜特拉叶蝉(Dutrapona reticulata sp. nov.)以及来自巴拿马科克莱的扎氏杜特拉叶蝉(Dutrapona zahniseri sp. nov.)。新属与赫卡拉波纳复合体(Hecalapona complex)的属相似,具有以下共同特征:体黄色无斑点,背腹扁平,额适度突出,前缘圆形且突出于复眼前缘之上,额与颜面过渡明显且细,上颚片窄,不延伸至唇基顶端,前翅具窄的叶状突。然而,杜特拉叶蝉属(Dutrapona gen. nov.)可通过以下特征组合与叶蝉族的其他属区分开来:单眼更靠近额的中线和后缘,额与颜面过渡呈匙形,有两条清晰的隆线,雄性第八腹节长大于宽,雄性阳茎基侧突具一对小的尾端具细齿的突起,亚生殖板短,阳茎具一对基部外侧的细长突起。
