Original Description

Phacoid shell twice as broad as the medullary shell, with eight pores in its radius. Arms nearly square, little larger than the phacoid shell, with broad truncated distal ends. The corners of the latter are so connected by the complete patagium, that the whole shell forms a regular octagon.

Size:
Diameter of the phacoid shell 0.1, of the medullary shell 0.05; length of the arms 0.12, distal breadth 0.11.

Editors' Notes
There was no illustration of this species in Haeckel (1887)
Haeckel listed Stauractura octogona the subgeneric name Stauracturium, but did not include the subgeneric name in the species name.[comment from RadWorld database]
