''Zygoballus'' is a genus of jumping spiders found in North and South America. ==Taxonomy and history== The genus was first described in 1885 by American arachnologists George and Elizabeth Peckham based on the type species ''Zygoballus rufipes''. The name derives from a combination of the Ancient Greek word ζυγόν (''zygon''), meaning "yoke", and the genus name ''Ballus''. The etymology of ''Ballus'' is unknown, but may be related to the Greek word βαλλίζω (''ballizo''), meaning "dance" or "jump about". The genus ''Messua'', based on the type species ''Messua desidiosa'', was synonymized with ''Zygoballus'' by Eugène Simon in 1903. Simon argued that ''Messua desidiosa'' was a transitional species which differed "much less from typical ''Zygoballus'' than would seem to be indicated by (Peckham's ) description." This synonymy was reversed by Wayne Maddison in 1996, and ''Messua'' restored as a valid genus. The genus ''Amerotritte'', based on the type species ''Amerotritte lineata'', was synonymized with ''Zygoballus'' in 1980 by María Elena Galiano. Galiano stated that the holotype of ''Amerotritte lineata'' was actually a very young ''Zygoballus'' specimen. ''Zygoballus'' is currently classified in the subfamily Dendryphantinae of the family Salticidae (jumping spiders). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Zygoballus」の詳細全文を読む スポンサード リンク
