Sertularelloides cylindritheca ( Allman, 1888)  

( Fig. 6 View FIGURE 6. A, B N–P)

Material examined. Stn. 1, 18.ii.2012, 13 m, M 214: several infertile stems, 7–12 mm high (MHNG-INVE- 82940); 26.ii.2012, 10– 15 m, M 261: a single sterile stem, 18 mm high (MHNG-INVE- 82941); M 265: several sterile stems, 11–22 mm high (MHNG-INVE- 82942); M 271: a single sterile stem, 20 mm high (MHNG-INVE- 82943).

Remarks. For the synonymy of this species, refer to Medel & Vervoort (1998). As noted by Kramp (1947, as Cnidoscyphus macrotheca   sp. nov.), the hydrothecae are borne on a short, distal apophysis of the stem/branch internodes, and its cavity "is separated from that of the internodium by a strong chitinous septum, perforated by the coenosarc". This structure ( Fig. 6 View FIGURE 6. A, B O), as well as the presence of short stem apophyses supporting sessile hydrothecae, justify the assignement of this species to the genus Sertularelloides Leloup, 1937   .

Geographical distribution. Subtropical and tropical waters of eastern and western Atlantic (Medel & Vervoort 1998). The Caribbean records are summarized by Calder & Kirkendale (2005); to these, it should be added the present record from Martinique.
