Bimeria corynopsis — Peña Cantero, 2015: 370 – 373, figs 1 A, 2 A – B, 3 A – B (synonymy).
description
Measurements (in µm). Cnidome: microbasic euryteles (seen discharged) [range 8.5 – 9.5 x 5.0, mean 9.1 ± 0.3 x 5.0 ± 0.0 (n = 7); ratio, range 1.7 – 1.9, mean 1.8 ± 0.1 (n = 7)], desmonemes [range 5.5 – 6 x 3.5].
discussion
Remarks. Stems with up to three polyps, pedicels undulated and polyp tentacles with distinct distal knob (Fig. 2 A). Ecology and distribution. Shelf species collected at depths from 385 (Vanhöffen 1910) to 527 m (Peña Cantero 2014 a); present material between 231 and 240 m, epibiotic on Hydrodendron arboreum and Staurotheca nonscripta. East Antarctic distribution (Peña Cantero 2014 a), hitherto only known from the Davis Sea (Vanhöffen 1910; Peña Cantero 2014 a). Present material, which constitutes the third record for the species and the first one for the Ross Sea, off Moubray Bay, extending considerably its geographic distribution.
