摘要
In the present paper, Polyamia DeLong is firstly recorded with two new species ——Polyamia penistenuis, sp. nov. and Polyamia drepananiforma, sp. nov. from China. The type specimens are deposited in the Entomological Museum of the Northwest Sci-Tech University of Agriculture and Forestry, Yangling, Shaanxi, China.
多脉叶蝉属Polyamia DeLong 隶属于角顶叶蝉亚科Deltocephalinae角顶叶蝉族Deltocephalini, 由DeLong (1926) 把它作为Deltocephalus Burmeister 的7个亚属之一建立,当时包括15个种,这15个种前翅爪区外部翅脉网状且具有黑色或深褐色斑纹.DeLong & Sleesman (1929)根据阳基侧突和阳茎特征将该亚属提升到属级地位.Sinada & Blocker (1994) 对该属进行了修订,并将其分为2个亚属,描述了1个新亚属Copolyamia,模式种为Polyamia compacta (Osborn & Ball),包括23个种.指名亚属Polyamia模式种为Polyamia weedi (Van Duzee),包括17个种.Blocker et al. (1995)对属征作了进一步修订.本文首次报道该属在中国的分布,并记述2新种:纤茎多脉叶蝉Polyamia penistenuis, sp. nov. 和镰茎多脉叶蝉Polyamia drepananiforma, sp. nov..模式标本保存在西北农林科技大学昆虫博物馆.1. 纤茎多脉叶蝉Polyamia penistenuis,新种(图1~7)本新种与Polyamia nidula DeLong & Thambinuttu相似,但本种阳茎末端完整,可与Polyamia nidula 相区别.正模:♂,海南两院(儋州县),灯诱,1983-Ⅵ-01,张雅林.词源:本种以纤细的阳茎而命名.2. 镰茎多脉叶蝉Polyamia drepananiforma, 新种(图8~15)本新种与Polyamia weedi (Van Duzee)相似,但本种阳茎基部叉状,可与Polyamia weedi (Van Duzee)相区别.正模:♂,陕西安康,1980-Ⅳ-23,马宁;副模:1♂,海南崖城,灯诱,1983-Ⅴ-11,张雅林.词源:本种因阳茎和连索侧面观形似镰刀而命名.
