Ophiura
Taxonomy
Ophiura was named by Lamarck (1801) [Sepkoski's age data: K Albi-u R]. It is extant. It is the type genus of Ophiuridae.
It was assigned to Ophiomastinae by Matsumoto (1915) and Wolburg (1939); to Ophiolepididae by Berry (1941); to Ophiurinae by Lyman (1865) and Spencer and Wright (1966); to Ophiurida by Sepkoski (2002); and to Ophiuridae by Stöhr et al. (2011) and O'Hara et al. (2018).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| H. Matsumoto 1915 | Disk low, flat, covered with plates and scales, among which the primaries are usually very prominent,. Radial shields usually separated from each other, sometimes more or less joined in pairs. Second oral tentacle pores open nearly or entirely outside oral slits,
very large, beset with numerous scales. Genital papillae, and usually also arm combs, present. Arms low, often flattened. Dorsal arm plates usually well developed and in contact with each other. Lateral arm plates low, those of the two sides being in contact with each other below. Three or more arm spines of variable length. Tentacle pores of one or two innermost pairs large and beset with rather numerous scales, but those beyond very small and beset with a few scales. | |
| S. Stöhr et al. 2011 | Disc low, flat, covered by small, imbricating plates, primary rosette usually distinct. Radial shields more or less separated. Arms not stout, gradually tapering, usually deep incisions next to arm bases (distal bursal slits). Dorsal arm plates well developed, adjacent plates usually contiguous, several proximal dorsal plates included in the disc, separating radial shields. Genital papillae well developed, arm combs present. Second oral tentacle pore opens into mouth slit, beset with numerous small papillae, which often form a continuous row with the oral papillae. Ventral arm plates much wider than long, usually separated,
at least outside disc. |
