Synonyms in the area: Dysmorphosa tenuis Browne, 1902 [medusa]; Hydractinia tenuis —Browne 1902; Browne & Kramp 1939; Pagès & Orejas 1999; Galea 2007 p. 25; Palma et al. 2011; Genzano et al. 2008a; Villenas et al. 2009; Podocoryne tenuis —Mayer 1910b; Browne & Kramp 1939 [medusa]; Podocoryne minuta —Pagès & Orejas (1999) [medusa] [non Dysmorphosa (Hydractinia) minuta Mayer, 1900]; Hydractinia minuta —Tronolone 2001; Migotto et al. 2002; Palma et al. 2007a p. 69-71, 73, 74, 2007b p. 74, 78, 80-81; Villenas et al. 2009; Bravo et al. 2011 [medusa].

Remarks: Hydractinia minuta was recorded by Pagès & Orejas (1999) for the Magellan region, and subsequently listed for South America by Tronolone 2001; Migotto et al. 2002; Palma et al. 2007a p. 69-71, 73, 74, 2007b p. 74, 78, 80-81. The species H. minuta was synonymized to H. carica by Broch (1916) and Rees (1956) after re-examination of type material. The South American occurrence of this species is disputable, because the species is “predominantly arctic” Schuchert (2008, p. 265). Recently, Galea (2007 p. 25) considered Dysmorphosa tenuis Browne, 1902 to be a junior synonym of Hydractinia tenuis Browne, 1902. Both records may refer to the same species and, presently, we keep the updated name Podocoryna tenuis (Browne, 1902)
