中文摘要：

昆明地区下寒武统沧浪铺组乌龙箐段所产的节肢动物Guangweicaris Luo, Fu et Hu, 2007，为研究寒武纪生命大爆发之后节肢动物辐射特征提供了重要资料。罗惠麟等（2007）在报道该节肢动物时，因标本不完整，对其头部和尾部特征均作了错误鉴别和描述。笔者根据完整且保存有软体附肢的标本，对Guangweicaris Luo, Fu et Hu, 2007作了重新研究和复原，据此讨论了该节肢动物的分类归属问题。

英文摘要：

Guangweicaris Luo, Fu et Hu, 2007 from the Lower Cambrian Canglangpu （Tsanglangpu） Formation provides significant materials for the study in Cambrian Animal Radiation. In reporting this arthropod of incomplete specimens, Luo Hui-lin et al. （2007） made an incorrect description with respect to morphological attributions of head and tail. This paper re-describes the structural character of Guangweicaris Luo, Fu et Hu, 2007 based on intact specimens attached by appendages or soft-bodied features and argues the classification question of this creature. In Guangweicaris Luo, Fu et Hu, 2007, there are three very narrow and short tergites in the prothorax that are covered by a head shield, and the endopods are similar to those of Fuxianhuia Hou, 1987 and Chengjiangocaris Hou et Bergstrom, 1991, interpreted as ‘the subchelate appendage＇ （Chenetal., 1995）or ‘the gut divercular＇ （Waloszek et al. , 2005）. These features have not been found in any other arthropods. Guangweicaris Luo, Fu et Hu, 2007, however, is closely related to Fuxianhuia Hou, 1987. Chengjiangocaris Hou et Bergstrom, 1991 and Shankouia Chen, Wang, Maas et Waloszek, 2004 and all of them belong to fuxianhuiid arthropods.
