Editors' Notes
There was no illustration of this species in Haeckel (1887)
Haeckel listed Sethodiscus micrococcus under the subgeneric name Sethodiscinus, but did not include the subgeneric name in the species name.

This species is assigned to Sethodiscus (the senior homonym) Haeckel, 1881a, p.457 (non p.430).[comment from RadWorld database]
