Remarks [by A.M.C.]. As Repometra arabica this species was originally included by 

 Mr. Clark in the subfamily Thysanometrinae, of which the species are mostly from 

 deeper water. On attempting to place it in the keys left by Mr. Clark I found that 

 its characters, particularly those afforded by the cirri, have greater affinity for the 

 characters of the Antedoninae, especially those species of the now merged Compsometra 

 and Antedon which have stouter cirri and flared pinnule segments, such as loveni, ser- 

 rata, bifida moroccana and duebeni (if the last two are distinct).
