Zootaxa 2016 2016-11-18 4194 1 1 256 Hutton, 1873 Hutton 1873 [151,565,1807,1832] Hydrozoa Sertulariidae Sertularella Animalia Leptothecata 120 121 Cnidaria species simplex  Remarks: Galea & Schories (2012a p. 46) considered that “Leloup’s (1974) material assigned to both  S. ellisif. lagenoidesand  S. peregrinamay belong to either this species [  Sertularellasp.] or  S. mixta, since no measurements allowing a reliable comparison were provided by this author”. Moreover,  Sertularella peregrinaBale, 1926is considered a synonym of  Sertularia simplexin WoRMS (Schuchert 2016). Given the uncertainties about these records, we conservatively include them in the synonym of  S. simplex, pending more detailed study. Distribution in SouthAmerica: polyp—Pacific Ocean, Chile, at north of Coquimboand in Puerto Melinka, Guaitecas Archipelago (Leloup 1974 p. 28, 31–32). Habitat: polyp—on algae (Leloup 1974 p. 28, 31–32).
