Corymorpha januarii Steenstrup, 1855

Synonyms in the area: Amalthea ? Hybocodon ? januarii —Mayer 1910 [medusa]; Amalthea ? januarii —Vannucci 1951a [medusa]; Corymorpha sp. Migotto & Silveira, 1987 [polyp]; Hybocodon unicus —Zamponi & Facal 1987; Genzano et al. 2009a [non Hybocodon unicus (Browne, 1902) ] [polyp].

Remarks: Vannucci (1951a) recorded Amalthea ? januarii (Steenstrup, 1854) for the region extended between Ilha Grande and Cabo Frio ( Brazil), based on the record of Amalthea ? Hybocodon ? januarii from Mayer (1910a) for Rio de Janeiro State. Migotto & Silveira (1987) recorded Corymorpha sp. for Ubatuba, subsequently reidentified as Corymorpha januarii Steenstrup, 1854 (Silveira & Migotto 1992) .
