Synonymy of Celerina & taxonomic comments. A.M. Clark (1967: 193) coined Celerina to separate Ferdina heffernani as different from other species of the paraphyletic genus Ferdina. Celerina heffernani was originally assigned to Ferdina based on the single linear series of furrow spines and homogeneous granulation on the surface of the adambulacral plate (Livingstone, 1931). However, a three-gene phylogenic survey of the Valvatida (Mah & Foltz 2011) showed C. heffernani and Fromia monilis as members of the same clade within the Goniasteridae supporting the hypothesis that the monotypic Celerina is a synonym of Fromia. Numerous others, including Livingstone (1931), A.M. Clark (1967), Marsh (1977), and Marsh and Campbell (1991) have all observed the close resemblance between C. heffernani and Fromia monilis.
Several characters point to Celerina and Fromia as synonyms. One of the diagnostic characters of “ Ferdina ” group goniasterids is the presence of continuous, uniform granular tegument but lacking spination or other accessory features on the adambulacral plates. Marsh and Campbell (1991: 214) also point out that Celerina differs based on sharply pointed adambulacral spines and that it is “not at all covered by granulated skin.” Furthermore, several specimen lots, including USNM E45982, CASIZ 113789, CASIZ 207329 and CASIZ 10446 all demonstrate short, pointed granules or spinelets on the surface of the adambulacral surface.This character is cited by A.M. Clark (1967: 194) in her description of Celerina heffernani. The presence of this latter character is inconsistent with the continuous, uniform granulated tegument present in other members of the Ferdina group members, further separating it from its original association with the other members and suggesting that it be best placed elsewhere, namely in the closely affiliated genus Fromia, with which it has shown “closest affinity” by Marsh and Campbell (1991).This is consistent with the synonymy as suggested by Mah and Foltz’s (2011) molecular tree. The alternating large and small superomarginal plate pattern, as described by A.M. Clark (1967) is also shared between the two genera (Fig. 1 A, B).
Although the genera are synonyms, Fromia heffernani displays distinct character differences from Fromia monilis and should remain a distinct species, pending further review. Abactinal and marginal plate morphology were compared for Celerina versus Fromia and although many characters, such as the abactinal and marginal plate shape and arrangement, were similar if not identical, other characters, such as the adambulacral accessories, furrow spination, elongate arms and color patterns are different.
