Original Description
Porodiscida with five forked chambered arms, without a patagium.

Etymology: From the Greek pentophiastrum = starrulet with five snakes"

Extra details from original publication
The genus Pentophiastrum differs from the two preceding genera by the bifurcation of the five arms, and can be derived either from Pentalastrum by the ramification of the distal ends of the arms, or from the similar Myelastrum by the increase in the number of arms.
