Reference | Diagnosis | |
---|---|---|
W. K. Spencer 1951 | A stenurid of the family Eophiuridae with well-plated disk with small overlapping scales, spines set parallel to the arm's length. Ambulacral basins shared subequally by two ambulacralia. Ambulacral axis broad and stiff. Paired mouth-angle plates broadly notched proximally | |
J. Dean Shackleton 2005 | Inferomarginal ossicles alternate bettween small and large size; additional spine-bearing ossicle in jaw causing mouth angle plate to be L-shaped. |
