半翅目鞘喙亚目是一类具有重要演化意义的昆虫。该亚目包括三个科:鞘喙蝽科(Peloridiidae)和卡拉蝽科(Karabasiidae)同属于鞘喙蝽总科;原臭虫科(Progonoci micidae)属于原臭虫总科。鞘喙蝽科是唯一的现生类群,孑遗于南半球。卡拉蝽科化石较丰富,但只发现于中亚、西伯利亚和蒙古中生代地层。本文重新描述广西西湾中侏罗统石梯组的Tegulicicada planaLin,1986,将其归入卡拉蝽科模式属Karabasia,建立一新组合Karabasiaplana(Lin,1986)comb.nov.。这是鞘喙蝽总科在中国的首次报道。该发现将鞘喙蝽总科在中生代的地理分布从暖温带地区(中亚、西伯利亚和蒙古)扩展到华南的亚热带或热带地区。同时,文中也总结了卡拉蝽科的化石记录。
Tegulicicada plana Lin,1986 from the Middle Jurassic of South China,is transferred to the genus Karabasia as Karabasia plana(Lin,1986) comb.nov.,and is re-described as the first Peloridioidea from China.This discovery extends the palaeogeographical distribution of Mesozoic Peloridioidea from the warm temperate zone(Central Asia,Siberia and Mongolia) to the subtropical and/or tropical areas of South China.An annotated list of species of Karabasiidae(fossil Peloridioidea) is presented.
