Original Description
Phacoid shell twice as broad as the medullary shell, with five pores on its radius, without a perfect chambered ring around it. Arms club-shaped, at the blunt distal end rounded, as long as the diameter of the phacoid shell; their basal breadth is one-fourth, their distal breadth one-half of its length.

Diameter of the phacoid shell 100µm, of the medullary shell 50µm; length of the arms 100µm, basal breadth 25µm, distal breadth 50µm.

Editors' Notes
Haeckel listed Trigonactura rhopalastrella under the subgeneric name Trigonacturium, but did not include the subgeneric name in the species name.
