The species of Swapansahooia consists of an elliptical base with a rim, four blocks and a central hole surrounded by struts. The distal process of Swapansahooia maghredaswampensis is hollow with a sombrero-like termination (containing 8-10 short spines). The morphological and optical properties of Swapansahooia maghredaswampensis align with those observed in the genus Swapansahooia.
