Sertularella areyi Nutting, 1904 Fig. 21h Sertularella areyi Nutting, 1904: 83, pl. 17, fig. 6. Type locality. Cuba: near Havana, 100–200 ftm (183–366 m) (Nutting 1904: 83). Material examined. Southwest Florida Shelf, outer shelf west of Sanibel Island, 26°16.67’N, 84°04.08’W, 137 m, 25 July 1981, triangle dredge, one colony fragment, 5 mm high, without gonophores, coll. Continental Shelf Associates, ROMIZ B1978. Remarks. Hydroids of Sertularella areyi Nutting, 1904 are small (usually less than 1 cm high) but quite striking in colony morphology. Long, slender internodes bear largely exserted and barrel-shaped hydrothecae having 1–3 annular ribs and a thickened hydrothecal rim. It has been reported few times in the western Atlantic, and gonothecae have yet to be described in specimens from the region. Although the type locality is off the north coast of Cuba, in the Gulf of Mexico, the species has been recorded much more frequently in the western Pacific (Korea, Japan, the Philippines, New Caledonia, Loyalty Islands, Australia, New Zealand), with fertile colonies having been described from there (Vervoort 1993; Hirohito 1995; Vervoort & Watson 2003). Elsewhere, records of S. areyi exist from Hawaiʻi, surprisingly from the inshore waters of Kâneʻohe Bay and Waikîkî (Carlton & Eldredge 2009). As well, Vervoort (1993) included S. capensis delicata Millard, 1964 from the east and south coasts of South Africa in the synonymy of the species. In the western North Atlantic, S. areyi is a species inhabiting waters of the continental shelf and upper slope, having been reported over a depth range between 17– 366 m. Geographically, it is known from offshore waters of South Carolina and Bermuda (Plantagenet Bank) in the north to Cuba (Nutting, 1904; Wenner et al. 1984; Calder 2000) in the south. The species has also been reported from Brazil (Oliveira et al. 2016). The only previous record from the Gulf of Mexico is Nutting’s (1904) original account of the species from the north coast of Cuba. This is the first report ...
