消室叶蝉属一新种(同翅目:叶蝉科:隐脉叶蝉亚科)

ONE NEW SPECIES OF THE GENUS CHUDANIA DISTANT (HOMOPTERA: CICADELLIDAE: NIRVANINAE)

消室叶蝉属Chudania由Distant建立于1908年,张雅林、杨集昆(张雅林,1990)对该属作了订正,将Chudania exposita Jacobi移出本属,报道了8个新种,使本属已知种数目增加到10种。本文报道1新种西藏消室叶蝉Chudania tibeta。正模()保存在西北农业大学昆虫博物馆,副模(1)保存在北京农业大学植物保护系昆虫标本室。

The genus Chudania was established by Distant in 1908, and revised by Zhang and Yang (Zhang Yalin, 1990). Up to now, there are 10 known species in the genus. One new species from Tibet is reported in the present paper. The holotype is deposited in the Insect Collection of the Entomological Museum, Northwestern Agricultural University (Shaanxi), and the paratype is kept in the Insect Collection of the Department of Plant Protection, Beijing Agricultural University.Chudania tibeta, sp. n.It is very similar to Chudania kunmingana Zhang et Yang, but its colour pattern and male genitalia is different from the latter. Its clavus of forewing is dark brown but the outer basal half of clavus with yellowish, subtriangular area. The clavus of forewing of the later is dark brwon without yellowish patch. Its paired appendages near middle of the aedeagus are slightly curved, extend basad and there are many small teeth on it, but that of the latter are straight, extend latterad, and there is no teeth on it. The pygofer appendages of both species are also different.
