See text Sagavia is a genus of trilobites that lived during the Middle and Upper Ordovician in what are now Northwest and Southeast China, North Kazakhstan and Wales.

It is a typical cyclopygid that can be distinguished by its large but separate eyes, elongated glabella, five thorax segments and a pygidium with clearly defined axis and border.

[1] The glabella of Sagavia is elongate with parallel sides or slightly converging towards the front.

The large eyes are separated at the front by the glabella and the cephalic doublure.

Sagavia has a pygidium with well a defined axis and border with clear furrows.
