Several characters in Chitonaster are similar to those in Eratosaster and Calliaster , including the elongate furrow spines, the relatively small actinal intermediate plate area, the presence of spines on the abactinal and marginal plates as well as resemblance in arm and disk shapes. Synonymy of Pentoplia . Pentoplia felli was described by H.E.S. Clark (1971) as the monotypic member of the Pentopliidae, a family that has since been synonymized into the Goniasteridae by Blake (1987). H.E.S. Clark (1971: 546) indicated that Pentoplia was reminiscent of Hippasteria and Chitonaster but did not elaborate on specific character comparisons, save for the absence of “characteristic” pedicellariae on Hippasteria . Pentoplia shares several characters with Chitonaster , including flat scalar, overlapping, abactinal plates, short blunt conical spines on the abactinal and ...

Body stellate. Abactinal plates flattened, scalar, overlapping and forming relatively thin body wall. Fasciolar channels weakly present to absent. Plate surface bare in most or with single large granule, blunt cylindrical and/or pointed spines, peripheral accessories absent. Marginal plates face laterally. Large pedicellariae, either bivalve or with enlarged flange-like valves (in C. felli , Fig. 5 B, D). Furrow spines one to three, typically two. Comments.
