Original Description
Cephalis large, flat, hemispherical, with subregular, hexagonal pores. Thorax flat, campanulate, nearly hemispherical; also with subregular, hexagonal pores, and with five stout ribs. The three primary ribs of the thorax are complete, and reach the peristome; the two secondary ribs (as basal branches of the two lateral ribs) are incomplete and absent in the distal half of the thorax. Peristome denticulate, with an elegant marginal corona of small square pores and short conical spines.

Size: Cephalis 0.03 long, 0.06 broad; thorax 0.1 long, 0.2 broad.

Editors' Notes
Haeckel listed Sethophormis pentalactis under the subgeneric name Pentaphormis and uses the other name, Pentaphormis pentalactis, in the figure description.[comment from RadWorld database]
