Symplectoscyphus glacialis
Description
Symplectoscyphus glacialis (Jäderholm, 1904)
(Fig. 3E)
Symplectoscyphus glacialis — Briggs, 1938: 32–33; Peña Cantero, 2010: 37–38 (synonymy). Material examined. 48EV194 , a mass of stems 80 mm in diameter, with gonothecae (IK–2012–10435) plus a stem fragment 30 mm long (IK–2012–10437).
Remarks. Symplectoscyphus exochus and S. glacialis are morphologically allied, both species having monosiphonic stems, irregular branching and similar hydrothecal shapes, but are easily recognizable by the shape of the gonothecae. The presence of two damaged gonothecae, and the size of the nematocysts (12 X 3.5), allow us to confirm the identification.
Ecology and distribution. Our material was collected at depths between 325 and 409 m, basibiont for colonies Abietinella operculata (Jäderholm, 1903), Bimeria corynopsis and Halecium interpolatum Ritchie, 1907, and with gonothecae in December. Reported by Briggs (1938), at depths between 630 and 720 m, from Commonwealth Bay. Antarctic-Kerguelen distribution (Peña Cantero 2010).
