| Summary: | Antennella aff. quadriaurita Ritchie, 1909 (Fig. 7K–N) Material examined. Stn. 8, 27.i.2012, 9– 15 m, M076: fertile (female) colony on Thyroscyphus marginatus (Allman, 1877). Additional material for comparison: Tristan da Cunha group, Inaccessible Island, Stn7. I10, 28.xi.2007, HRG-0341: several sterile stems. Remarks. Compared to the material from Inaccessible Island studied earlier by myself (Galea 2010b), the present specimens have smaller hydrothecae, the lateral nematothecae of the anterior pair are shorter (compare Fig. 7M1 and M2), and the ahydrothecate segments bear 3 or 4 nematothecae in two parallel, closely set rows (Fig. 7K), instead of only one, occasionally two. The cnidome of the Caribbean material is composed of three types of capsules (Fig. 7N1): 1) seed-shaped microbasic heteronemes, ca. 4.2×2.6 µm, occurring rarely in the coenosarc; 2) small, banana-shaped microbasic mastigophores, ca. 6.4×2.2 µm, abundant in the tentacles, also scattered in the coenosarc; 3) large, ovoid microbasic ... : Published as part of Galea, Horia R., 2013, New additions to the shallow-water hydroids (Cnidaria: Hydrozoa) of the French Lesser Antilles: Martinique, pp. 1-50 in Zootaxa 3686 (1) on pages 29-30, DOI: 10.11646/zootaxa.3686.1.1, http://zenodo.org/record/284148 ... |
