YKLP 11564a, a nearly complete specimen in dorsal view, showing three prothoracic tergites, five opisthothoracic tergites and seven abdominal tergites. B. YIGS Kgs-1-36 (paratype), prothoracic tergites in dorsal view. C. YIGS Kgs-1-37 (paratype), isolated opisthothoracic tergite in dorsal view. D. YKLP 11140, last two prothoracic and five opisthothoracic tergites in lateral view, appendages are detached from the body. E. YKLP 11162b, last prothoracic, five opisthothoracic and first two abdominal tergites in lateral view.
context_page_description: Guangweicaris is an extinct genus of fuxianhuiid arthropod known from the Cambrian period. It is only known from the type species Guangweicaris spinatus, which is known from the Cambrian Stage 4 Guanshan Biota near Kunming. It is currently the latest known fuxianhuiid. It was first described in 2007, and was given a comprehensive re-description in 2020. It is currently known from over 150 specimens. Within the fuxianhuiids it is sister to Fuxianhuia, together forming the clade Fuxianhuiidae. In comparison to Fuxianhuia it has a wide, oval shaped opisthothorax and a proportionally longer, narrow tail-like abdomen, with 3 prothoracic tergites, 5 opisthothoracic tergites and 7 abdominal tergites, it also possesses a row of spines running down the central axis of the body from the second opisthothoracic tergite.
