| 摘要: |
| 本文运用分支分类学的特征分析方法,对歧脊沫蝉属Jembrana Distant的外部形态学、雄性外生殖器结构以及生物学方面的资料加以分析比较。歧脊沫蝉属持有许多一般尖胸沫蝉科Aphrophoridae的科级特征(共同祖征),依此反映其进化历史,决定其分类隶属,说明其与所有的尖胸沫蝉科沫蝉类起源于一个共同的祖先。该属与同科的尖胸沫蝉属Aphrophora Germar表现有许多共同离征,证明它们是自一个共同的原始尖胸沫蝉科沫蝉类祖先演化而来的单系类群。而与尖胸沫蝉属相比较,歧脊沫蝉属具有许多更特化的离征及个别较原始的祖征,这种相对原始和相对特化的特征的镶嵌分布,暗示它们是一对属级的姐妹群。 |

| Abstract: |
| In the present paper comparisons are made through analysis of charactcrs with cladistic taxononmic method of the external characters, main male genital structures and biological features of Jembrana Distant.Jembrana Ctovia Stal of the family Aphrophoridae serves as the out-group. Jembrana exhibits a large number of characters (both apornorphic and plesiomorphic) common to tall aphrophorids. This shows that Jembrana has a crrmion ancestor with all aphrophorids. The Jembrana and Aphrophora Germar of the Aphrophoridae possess many synapomorphies in common and consequently together they form a monophyletic group derived from a common primitive aphrophorid ancestor. But, compared with Aphrophora, Jembrana further exhibits many derivative apomorphies and a few primitive plesiomorphies. The genus Jembrana seems to be more advanced in systematic position than the genus Aphrophora because of its being provided with more aciaptative mechanisms and because of the recency of branching forth from the common ancestor. |
