|Classification and/or Status||
Differs from the type species of Offaster only in having a flatter and more quadrate shape with the periproct much higher in posterior profile. The poorly known Messaoudia is identical in shape but apparently lacks a marginal fasciole. Differs from Holaster in having a more obsolete frontal groove and in possessing a marginal fasciole.
