Stauridiosarsia nipponica (Uchida, 1927)

Synonyms in the area: Coryne nipponica —Vannucci 1949, 1951a; Migotto 1996; Migotto et al. 2002; Silveira & Morandini 2011 [polyp and medusa]; Zamponi 1983a; Genzano et al. 2008a [medusa]; Shimabukuro 2007 [polyp]; Sarsia (Staurodiosarsia) producta —Vannucci 1949, 1951a [polyp]; Stauridiosarsia producta —Ramírez & Zamponi 1981; Zamponi 1983a [medusa]; Coryne producta —Migotto 1996 [polyp and medusa]; Shimabukuro 2007 [polyp]; Genzano et al. 2008a [medusa]; Silveira & Morandini 2011 [polyp and medusa]; Miranda et al. 2015 [polyp]; Sarsia producta —Migotto et al. 2002; Silveira & Morandini 2011 [polyp and medusa] [non Sarsia producta (Wright, 1858)].

Remarks: Migotto (1996:21) recorded Coryne producta for the Brazilian coast, a record subsequently reassigned to Coryne nipponica (Uchida, 1927) by Schuchert (2001 p. 759–761). The same record is incorrectly mentioned as Coryne japonica (Nagao, 1962) in Migotto et al. (2002) . We believe all records related to Coryne producta, a species with a North Atlantic distribution, would be, indeed, Coryne nipponica . The distribution range provided by Ramírez & Zamponi (1981) is not based on specific records and, therefore, we did not consider that information for this species.

Distribution in South America: polyp—Atlantic Ocean, Brazil, from 23.50°S to 25°S (Vannucci 1949, 1951a; Migotto 1996; Migotto et al. 2002; Shimabukuro 2007; Silveira & Morandini 2011; Miranda et al. 2015); medusa—Atlantic Ocean, Brazil to Argentina, from 24°S to 46.78°S (Vannucci 1949, 1951a; Zamponi 1983a; Migotto 1996; Migotto et al. 2002; Genzano et al. 2008a; Silveira & Morandini 2011).

Habitat: polyp—shallow waters from 0.5 to 1m depth, on algae, mussels, barnacles (Migotto 1996; Oliveira & Marques 2007; Shimabukuro 2007).
