Original Description

Cortical shell hexangular, equilateral, four times as broad as the circular, Triopyle-shaped medullary shell. Surface spiny. Three arms nearly of the same form and size as the three triangular gates between them. (Similar to Hexapyle sexangularis, but differing in the irregular loose network closing the gates.)

Diameter of the disk 0.18, of the gates 0.06. [dimensions in mm]

Etymology:
Latin sex- + angularis -is -e = having six corners

Editors' Notes
There was no illustration of this species in Haeckel (1887)
Haeckel here refers to Hexapyle sexangularis. This species name is not known and he apparently intends H. sexangula.
