Checked: verified by a taxonomic editorStatus The status of the subgenera proposed by Fisher (1940) needs reassessment. A.M. Clark (1989: 205) treats the absence of webbing on the oral spines as of supraspecific weight but Downey (1992) does not agree and treats Pteraster stoibe H.L. Clark (1941) without webbing, as a subspecies of P. militaroides, which does have webs linking the oral spines of each plate. Downey notes that the absence of webbing in the holotype of stoibe might be an artefact of preservation but in other species of Apterodon, this appears to be the natural condition.

As a compromise, rather then segregate the species listed as Pteraster (Retaster) and Pteraster (Apterodon) by Fisher (1940) or subsequently referred to these subgenera, all are included under the heading of Pteraster[details]
