摘要 描述了采自云南西双版纳热带雨林的蟹蛛 1 新属高峭蛛属及 1 新种胶高峭蛛 Acrotmarus gummosus gen. et sp. nov.。新种模式标本保存在中国科学院动物研究所。高峭蛛属,新属 Acrotmarus gen. nov.与蟹蛛科蟹蛛亚科峭腹蛛族中的其它属的主要区别在于: 后侧眼眼丘大而隆起,雄蛛触肢插入器呈薄片状,基部有宽缘,其端部具 1 凹陷,末端呈钩状。本属近似于非洲的Pherecydes O . P. -C ambridge,1883,但有以下不同: 前者仅后侧眼在隆起的眼丘上,后者的前侧眼、后侧眼均在隆起的眼丘上; 前者雌蛛的后侧眼间距/头胸部宽为 0. 93,后者为1. 29; 前者雌蛛前中眼间距 / 前中、侧眼间距为 0. 97,后者为 1. 52。本属的生殖器官结构与 Pherecydes 差异明显: 前者雄蛛触肢有 VTA 而后者缺乏,前者插入器扁平片状而后者丝状; 前者外雌器有兜而后者无。词源: 新属属名由于标本系从高层雨林冠层采集而来,且与峭腹蛛族的属在外形上有相似性。胶高峭蛛,新种 Acrotmarus gummosus sp. nov. ( 图 1 ~3,6~ 21)正模♂。副模: 24♂♂ ,15♀♀,云南省西双版纳国家自然保护区勐仑保护区的热带雨林及橡胶林,2007 年 7 ~ 8月间,郑国采; 1 ♂ ,西双版纳勐仑镇绿石林森林公园,2009 年 11 月 15 日,唐果、姚志远采。词源: 新种种名源自新种部分标本采于橡胶林冠层。 A small sized crab spider of the family Thomisidae, subfamily Thomisinae, tribe Tmarini collected from Xishuangbanna, Yunnan, China is studied. Acrotmarus gen. nov. is erected to accommodate Acrotmarus gummosus sp. nov. The new monotypic genus is diagnosed in this study.
