中国尼蝉属的分类研究(同翅目:蝉总科)

A STUDY ON CLASSIFICATION OF THE GENUS NIPPONOSEMIA KATO (HOMOPTERA: CICADOIDEA) FROM CHINA

尼蝉属Nipponosemia是Kato(1925)根据Abroma terminalis Matsumura建立的。分布于中国(四川、华南、台湾等)和日本。 本属的主要特征是:体中等大小;头冠(包括复眼)宽于中胸背板基部;其前缘呈圆弧形;背瓣大、盖住鼓膜;腹瓣大、纵长,左右内缘靠近;前、后翅透明,顶角或外缘常有褐色斑纹。雄性外生殖器的抱钧呈小钩状,左右远离,阳茎末端呈刺状分裂;雌性产卵管稍超出腹末。多栖息于叶片或小枝上,鸣声不大,多为“吱！—咬！—吱！……！”回声。

The genus Nipponosemia was established byKato (1925)based on Abroma terminalis Matsumura. It was placed in the tribe Tibicenini based on the characteristics of the male sound -producing apparatus.But the characters of the male genitalia are more allied to the genus Mogannia of the tribe Moganiini (Hayashi, 1974)and to the genera of the tribe Cicadini. The characteris- tics of the male sound-producing apparatus of the genus Nipponosemia are also allied to both Cicadini and M oganiini. But considering structures of the body and characteristics of their biology. Especially the head non-conical and the width of the head (including eyes) being slightly wider than the base of the mesonotum, the genus Nipponosemia is more allied to the tribe Cicadini. Thus Nipponosemia should be separated from the Tibicenini and placed in the Cicadini.The type specimens are deposited in the Entomological Museum of the Northwestern Agricultural University, Yangling, Shaanxi, China.Key to Species of the Genus Nipponosemia1.Apical angle of tegmina with fuscous spots 2Apical angle of tegmina without fuscous spots N. virescens2.Fuscous spots are located only in the first and second apical areas of the tegmina, the outer margin ofwing without fuscous spot N. terminalisFuscous spots are located in the first to seventh apical areas of the tegmina and the outer margin of wing 33. M esonotum with four obconical black spots on mid line of anterior margin; the length of body about20 mm N. metulataM esonotum only with two obconical black spots on midline of anterior margin ; the length of body about 26 mm N. guangxiensis1.Nipponosemia metulata Chou et Lei, sp. nov. (Pigs. 1 - 5)This species resembles N. terminalis (Matsumura), but with a smaller body. The marginal spots on tegmina and wings are larger, the ovipositor sheath extends slightly beyond the end of abdomen, and the uncus and aedeagus are obviously different.Holotype: , Longrui Ningming, Guangxi Zhuang Aut, Reg., 16- V -1984, Meng Tian Leg., No. 0349. Paratype: 1 , Wuwang Sanlian, Guangxi Zhuang Aut. Reg. 17- VI -1980, Xi Fusheng Leg., No. 5104.2.Nipponosemia guangxiensis Chou et Wang,sp. nov. (Pigs. 6-10)This species resembles N. terminalis (Matsumura), but with a larger body. The marginal spots of the first to seventh apical areas of the tegmina are larger and fuscous, while the wing marginal spots and margins of anal areas are also fuscous; the pronotum is without spot; mesonotum only with two obconical black spots on midline of anterior margin, the remainder green and the aedeagus and uncus are obviously different.Holotype: , Nenggang, Guangxi Zhuang Aut.
