Diagnosis
ReferenceDiagnosis
D. B. Blake and R. Reid 1998Adult size apparently small, form pentagonal, sides straight to weakly concave. Abactinals tabulate, large relative to disk size, primary circlet ossicles enlarged. Marginals between interbrachial axis and arm tip three in number, very small fourth on largest individuals. Second and third superomarginals abutted along mid-line. Marginals high, outer surface broadly arched, with small, rather widely spaced pustules about 0.25 mm in diameter, these bearing slender spinelets. Pustular groove developed along adradial margin of superomarginals.
