'''''Sagavia''''' is a genus of [trilobite](/source/trilobite)s that lived during the [Middle and Upper Ordovician](/source/Ordovician) in what are now Northwest and Southeast China, North Kazakhstan and Wales. It is a typical [cyclopygid](/source/Cyclopygidae) that can be distinguished by its large but separate eyes, elongated glabella, five thorax segments and a pygidium with clearly defined axis and border.[{{cite journal|author1= Zhou Zhiyi|author2= Zhou Zhiqiang|year= 2007|title= The Late Ordovician cyclopygid trilobite ''Sagavia'' Koroleva, 1967, from the Pagoda Formation of southwestern Shaanxi, China|journal= Memoirs of the Association of Australasian Palaeontologists|volume= 34|pages= 181–187|url= http://159.226.74.248:8000/pagelinks/131880.pdf|access-date= 18 June 2013|archive-date= 19 May 2018|archive-url= https://web.archive.org/web/20180519034505/http://159.226.74.248:8000/pagelinks/131880.pdf|url-status= dead}}]
