Original Description

All three arms equal and equidistant. Each arm has the form of an isosceles triangle, twice as high as broad; the truncated apex of the triangle is inserted into the large central disk, whilst its distal base (four times as broad) is divided by a deep incision (half as long as the arm). Each arm with ten to twelve joints, simple in its basal half, double in its distal half. Axes of the six branches straight. (Resembles Trigonastrum regulare, Pl. 43, fig. 16, but differs in the absence of a patagium.)

Size:
Radius of each arm 240µm, greatest breadth 110µm, basal breadth 30µm.

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