Symplectoscyphus filiformis (Allman, 1888)

Synonyms in the area: Sertularia gracilis Allman, 1888 p. 51–52 [polyp]; Sertularella filiformis —Nutting 1904 p. 97; Hartlaub 1905 p. 636–637 [polyp]; Sertularella filiformis var. reticulata Ritchie, 1907a [polyp].

Remarks: an exhaustive comparative analysis of materials with a broad geographic distribution, ideally including molecular markers, is necessary to resolve the status of the species Symplectoscyphus subdichotomus and Sertularella filiformis (cf. with remarks by Galea & Schories 2012a p. 47–48).

Distribution in South America: polyp—Pacific Ocean, Chile, at 39.85°S 73.44°W, and from 41.67°S to 53.62°S (Allman 1888 p. 51–52; Nutting 1904 p. 97; Hartlaub 1905 p. 636–637; Galea 2007 p. 68–69; Galea et al. 2009a p. 341; Galea & Schories 2012a p. 46–48); Atlantic Ocean, Argentina, at 42.78°S 58.77°W, from 52.38°S to 54.42°S (Ritchie 1907a; Totton 1930; Blanco 1982, 1984, 1994a; Genzano & Zamponi 1997).

Habitat: polyp—from 5 to 610m depth, on hard substrates, mollusc shells, sponges, worm tubes and hydroids (Ritchie 1907a; Totton 1930; Blanco 1982, 1984, 1994a; Galea 2007 p. 68–69; Galea et al. 2009a p. 341; Galea & Schories 2012a p. 46–48).
