Schizotricha falcata Peña Cantero, 1998

Schizotricha falcata Peña Cantero, 1998: 78 –79, fig. 1; 2008: 456; 2013: 129; Peña Cantero & Vervoort, 1999: 361 –362 (synonymy); 2005: 803.

Material examined. Stn 13, stem 170 mm high on pebbles (MNCN 2.03/664); Stn 15, stem 410 mm high, with female gonothecae (NIWA 117325).

Ecology and distribution. Shelf species ( Peña Cantero & Vervoort 2005), found at depths between 73 ( Peña Cantero & Vervoort 2005) and 248 m ( Peña Cantero 2008); present material between 466 and 535 m, notably extending its lower bathymetric limit. Hydrorhizal stolons attached to gravel and pebbles ( Peña Cantero 2008; present material). Used as substratum by other hydroids ( Peña Cantero 2008, 2013). Gonothecae in January (Peña Cantero 1998, 2008) and February (Peña Cantero 2013; present material).

Considered endemic to West Antarctica ( Peña Cantero & Vervoort 1999), being known off Low Island ( Blanco 1984; Peña Cantero 2013), King George Island (Peña Cantero 1998), and Deception Island ( Peña Cantero 2008), in the South Shetland Islands area, off Astrolabe Island, Antarctic Peninsula, and off Anvers Island, Palmer Archipelago ( Peña Cantero & Vervoort 2005). Present material is the first record from the Ross Sea and from East Antarctica , collected off Possession Islands, suggesting a circum-Antarctic distribution.
