biology_ecology
Ecology and distribution. Previously found at depths between 231 (Peña Cantero 2017) and 527 m (Peña Cantero 2014 a); present material at 710 – 758 m. Hitherto considered as endemic of East Antarctica (Peña Cantero 2014 a); present finding, the fourth report of the species, and the first for both the Weddell Sea and West Antarctica, points to a circum-Antarctic distribution.

(Fig. 2 a – c)
discussion
Remarks. In spite of being scarce, our material perfectly agrees with the description of the syntypes examined by Peña Cantero (2015), including the slightly-capitate appearance of tentacles (Fig. 2 c), which has been considered as the diagnostic trait of the species (see Schuchert 2007). Cnidome consisting in microbasic euryteles [range 7.5 – 9 x 5.0 – 5.5 µm, mean 8.6 ± 0.5 x 5.2 ± 0.3 µm (n = 21)] and desmonemes [range 4.5 – 5.0 x 3.0 – 3.5 µm, mean 4.7 ± 0.4 x 3.3 ± 0.3 µm (n = 16)].
