中国尖胸沫蝉科族的系统发育及一新族的建立(同翅目:沫蝉总科)

本文应用Kluge and Farris的Wagner数量分析法对我国尖胸沫蝉科(Aphrophoridae)的铲头沫蝉族Cloviini,象沫蝉族Philagrini,尖胸沫蝉族Aphrophorini,长沫蝉族Phil-aenini及棘茎沫蝉族,新族Capnodistini trib.nov.之间的系统发育关系进行了分析,结果推得两个明显的组群,即(Cloviini+Philagrini)+(Aphrophorini)和(Philaenini+Capnodistini trid.nov.),它们互为姐妹群关系,共同形成一个全系分支(holophyleticClade)。文中建立一新族棘茎沫蝉族Capnodistini trib.nov.该族定义为触角檐具檐沟,阳茎有6～8条棘刺,其模式属指定为Capnodistes Breddin 1903。

THE PHYLOGENY OF FIVE TRIBES OF THE CHINESE APHROPHORIDAE (HOMOPTERA: CERCOPOIDEA), WITH PROPOSAL OF A NEW TRIBE CAPNODISTINI

In this paper, the interrelationships among five tribes of the Chinese Aphrophpridae i..e. Cloviini, Philagrini, Aphrophorini, Philaenini and Capnodjstini trib.nov.are discussed, by means of the phylogenetic method of Kluge and Farris (1969) , and Capnodistini trib.nov.is erected to accommodate, the genera Capnodistes Breddin 1903, Dinda Distant 1908 and Doha Distant 1908.Ten morphological characters have been selected for the phy-logenetic analysis. Polarities were assigned based upon comparison with the states found in the tribe Ptyelini which serves as the out-group. The result obtained is shown in the cladogram 5. Capnodistini trib.nov. (type-genuss Capnodistes Breddin 1903) is recognized by the antennal ledges sul-cated and aedaegus armed on the lateral edge with 6 - 8 long spines.
