| Summary: | Zyzzyzus parvula (Hickson & Gravely, 1907) (Fig. 5 a–h) Material examined. ANT XVII/3: 111-9, numerous polyps, up to 45 mm high, on E. generale, H. interpolatum, Sc. unifurcata and T. longstaffi, with mature gonophores; 111-18, a single polyp, c. 1 mm high, on Lafoea dumosa (Fleming, 1820). Remarks. As also mentioned by Svoboda & Stepanjants (2001), many juveniles have been observed sharing substrate with adults, pointing to a gregarious habit, and putatively restricted dispersal capabilities. Juvenile specimens, especially the youngest ones, have slightly capitate aboral tentacles (Fig. 5a), which is in agreement with the genus diagnoses by Campos et al. (2007). Originally described from the Ross Sea as Lampra parvula Hickson & Gravely, 1907, the species has had a complicated taxonomical history, being re-allocated in several genera, even belonging to different families. It was considered as Corymorpha by Stepanjants (1972), and later re-allocated in Lampra by Stepanjants & Svoboda (1999). ... : Published as part of Soto, Joan J. & Peña, Álvaro L., 2019, Benthic hydroids (Cnidaria, Hydrozoa) from the Weddell Sea (Antarctica), pp. 1-78 in Zootaxa 4570 (1) on page 17, DOI: 10.11646/zootaxa.4570.1.1, http://zenodo.org/record/2608527 ... |
