偏角飞虱属分类研究(同翅目,蜡蝉总科,飞虱科)

A TAXONOMIC STUDY OF THE GENUS NEOBELOCERA (HOMOPTERA, FULGOROIDEA, DELPHACIDAE)

对偏角飞虱属NeobeloceraDingetYang的种类进行了系统整理,共4种,即偏角飞虱Neobeloceraasymmetri caDingetYang (云南)、浙江偏角飞虱N .zhejiangensis (Zhu) (浙江、安徽)、汉阴偏角飞虱N .hanyinensisQinetYuan (陕西)、兰坪偏角飞虱N .lanpingensisChen (云南)。对属征进行了拟定,编制了种检索表,简述了已知种的分布、寄主。描记了采自湖南张家界国家森林公园的1新种,即侧刺偏角飞虱N .laterospinasp .nov .,提供了该新种及兰坪偏角飞虱N .lanpingensisChen的特征图。研究标本及新种模式标本保存于贵州大学昆虫研究所。

Five species (including a new species) of the genus Neobelocera Ding et Yang (Homoptera, Fulgoroidea, Delphacidae) are recognized. The illustrations of the new species N. laterospina sp. nov. and N. lanpingensis Chen, 2003 are given and a key to species is presented. All specimens, including the types of new species, are deposited in the Institute of Entomology, Guizhou University.1 Neobelocera asymmetrica Ding et Yang, 1986 Neobelocera asymmetrica Ding et Yang, 1986.

Body length ♂ 2.8-2.9mm, ♀ 3.2-3.5mm; including teg. ♂ 4.9-5.1mm, ♀ 5.4-5.7mm; tegmen length ♂ 4.1-4.4mm, ♀ 4.6-4.7mm. This new species is related to N. lanpingensis Chen, but can be easily distinguished from the latter by the following characters: frons without pale transverse stripe below level of lower margin of eyes; ventral margin of pygofer concaving at middle, without medioventral process; genital styles with a long process subapically; aedeagus not forked at base, suddenly fold at basal 1/3, with 2 processes at apex. Holotype ♂, paratypes 7♂♂, 2♀♀, Zhang- jiajie Park (26°52′N, 104°17′E), Hunan Province, 9 Aug. 2001, coll. by CHEN Xiang-Sheng. Etymology. The species name is derived from the Latin, “latero-” and “spina”, referring to the pre- sence of lateral, long spines on the ventral margin of male pygofer. Host plant. Indocalamus sp. Distribution.
