Comments. Mediaster includes 18 nominal species ( A.M. Clark 1993, Mah 2015b) which occur in the Atlantic and Pacific Oceans and is among the earliest genera of starfishes described from the Pacific coast of North America ( Stimpson 1857). Fisher (1911) reviewed two species present from the North Pacific , M. aequalis and M. tenellus and discussed taxonomic relationships among Atlantic and Pacific species. Carey (1972) subsequently discovered “ Mediaster elegans ” (= Bathyceramaster careyi n. sp) from deep-sea settings off the coast of Oregon.

Fisher (1911) pointed out the absence of the stellate radiating base, a defining characteristic of the genus, in the tropical East Pacific “ Mediaster elegans " Ludwig 1905 but did not undertake a revision of the group. During the course of this investigation both “ Mediaster elegans ” Ludwig 1905 and the species described by Carey (1972) as “ M. elegans ” were both found to be lacking the diagnostic synapomorphy for Mediaster and have since been reassigned to the new genus Bathyceramaster n. gen. (as above).
