Ophiocomella sexradia ( Duncan, 1887)

Fig. 4 View FIGURE 4

Ophiocnida sexradia Duncan, 1887: 92 , pl. 8, figs 10, 11.

Ophiocomella sexradia — Devaney 1970: 29–31 ; O’Hara et al. 2019: 68.

Material examined: Persian Gulf, Iran, Qeshm Island, intertidal, hand collected, February 2019, collector Yaser Fatemi, 1 spm, 3.9 mm dd [SMNH-178932].

Habitat: Intertidal hard bottom (present study) ( Fig. 2F View FIGURE 2 ).

Persian Gulf and Gulf of Oman: Qeshm Island (10), new record (present study).

Indian Ocean: West Indian Ocean and Red Sea ( Clark & Rowe 1971), Mozambique ( Clark & Courtman-Stock 1976), Madagascar ( Cherbonnier & Guille 1978), Seychelles ( Clark 1984), Gulf of Mannar ( James 1988), Mascarene Isl. ( Boissin et al. 2016), South Africa ( Olbers et al. 2019).

Remarks: This species shares with Ophiactis savignyi the hexamerous body symmetry and banded color pattern. It can be distinguished by the numerous conical dorsal disc granules, three oral papillae and a cluster of tooth papillae. O’Hara et al. (2019) suggested that all hexamerous species of Ophiocomella ( O. ophiactoides (H. L. Clark, 1900) , O. schmitti A. H. Clark, 1939 , O. sexradia ) may form an asexually reproducing complex with wide distribution, rather than separate species. The name O. sexradia has priority.
