The Chinese Hecalina (Hemiptera: Cicadellidae: Deltocephalinae: Hecalini) with descriptions of a new genus and seven new species

摘要

The Chinese Hecalina (Deltocephalinae: Hccalini), which consists of five genera, is reviewed. Coloration and shape of the head and body, venation of forewing, and genitalia structures are the main morpological characters utilized to distinguish taxa. Fangamanus gen. n. is proposed for Parabolocratus tripunctatus Matsumura (type species of the new genus) and two other species. A key to the five genera of the Chinese Hecalina (Fangamanus gen. n., Hecalus Stal, Hecalusina He et al., Linnavuoriella Evans, and Thomsonia Signoret) is given, and seven new species from China are described: Hecalus changjiaotus, H. feithailandus, H. nadanus, H. triundosus, H. yuanmouensis, Thomsonia breviaea, and T daliensis. In addition, four new combinations are proposed: Thomsonia nitobei (Matsumura), Fangamanus rufofascianus (Li), F. tripunctatus (Matstunura) (n. rec.), and F. morrisoni (Kwon and Lee). Only seven previously described species from China remain in Hecalus Stal: H. bifurcatus Cai & Wang, H. furcatus Morrison, H. henanus Cai & Shen, H. katoi Metcalf, H. prasinus (Matsumura), H. thailandensis Morrison, and H. wallengreni (Stal) plus two species (H. paykulli Stal and H. lefroyi Distant) previously recorded but unconfirmed here from China. Four species are redescribed: Fangamanus rufofascianus, F. tripunctatus, Thomsonia porrecta, and the first description and illustration of the male of T. nitobei (Matsumura) are provided.
