Ophiocoma pusilla


Ophiocoma pusilla  ( BROCK, 1888) complex

(UF- 6596, Fig. 4View FIGURE 4 f, KU 594364View Materials)

Material. 1 spm, St. 2; 1 spm, St. 5

Remarks. This small species (DD<1cm) is easily distinguished from other Ophiocoma  by its angular dorsal arm plates and its thinner, hollow arm spines. COI sequence data indicates that SWIO populations are deeply divergent from populations in W Australia and the Pacific (Boissin et al. in revision). The type locality lies in the W Pacific ( Ambon, Olbers & Samyn 2012), thus we attribute these specimens to the species complex. Abundance: 1.

Distribution. An uncommon species that is nevertheless widespread from the Red Sea to the Pitcairn Islands across the IWP ( Clark & Rowe 1971, Devaney 1970); previously reported from Réunion ( Guille & Ribes 1981).
