TAXONOMY OF EVACANTHINI OF TAIWAN (HOMOPTERA: CICADELLIDAE: CICADELLINAE)

臺灣產橫脊葉蟬之分類學(同翅目:葉蟬科)

摘要


Fourteen species of Evacanthini are listed as inhabiting Taiwan, belonging to 8 genera in 2 tribes. Two new genera (Processus and Penuria) and 6 species are described: Pythamus chia baotawow, Onukia chiangi, Paraonukia ochra, Onukiades longitudinalis, Processus bifasciatus and Penuria tengchihugh. These are here divided into four monophyletic groups, base on a phenetic analysis using 112 morphometric characters. One species not collected by the author is listed in this work and reproduced for the sake of completeness.

並列摘要


本研究共分二部份,第一部份是傳統分類學,這部份共敍述2族8屬14種橫脊葉蟬,其中有2新屬6新種,分別爲:Pythamus chiabaotawow sp. nov., Onukia changi sp. nov. Paraonukia ochra sp. nov., Oniukiades longitudinalis sp. nov., Processus bifascius gen. et sp. nov.及Penurugh tengchihia gen. et sp. now.;同時將臺灣産橫脊葉蟬依其形態分爲四群。第二部份是以表型學派的方法,以UPGMA類聚法來分析112個形態測量值,以推演出臺灣産橫脊葉蟬之關係。結果顯示表型分析可區別出種間外在形態之差異,但無法反映出傳統分類之系統關係。另外一舊有種並沒有採集到,但也列出,以使此篇報告具有完整性。
