Notes on Yangiella Hsiao (Hemiptera: Aradidae: Mezirinae), with description of a new species from China

摘要

The aradid genus Yangiella Hsiao is reviewed. Two species are recognized. The type-species, Y. mimetica Hsiao, is redescribed and the new species, Y. montana Zhang, Bai, Heiss & Cai, is described. A key to species is given and the diagnostic morphological features of the two species are illustrated. Yangiella Hsiao was erected by Hsiao in 1964 from Yunnan, China. The genus is similar to Neuroctenus Feiber, but sterna IV to VI are without basal carina and the genae bend upwards in anterolateral view.Only one species, Yangiella mimetica, has been known in the genus prior to this study (Hsiao 1964, Liu 1981, Kormilev & Froeschner 1987, Heiss 2001). In a study of the Chinese aradids, we found a remarkable species of this genus from Yunnan and Guangxi in China, which is here described as new.
