RODRIGUEZ, Carolina; GENZANO, Gabriel  and  MIANZAN, Hermes. First record of Eutonina scintillans Bigelow, 1909 (Hydrozoa: Leptomedusae: Eirenidae) in temperate waters of the southwestern Atlantic Ocean. Investig. mar. [online]. 2007, vol.35, n.2, pp.135-138. ISSN 0717-7178.

We herein report the Leptomedusae Eutonina scintillans (Bigelow, 1909) for the Buenos Aires coast (38°S) as a consequence of a research project dealing with hydromedusae distributions in the southwestern Atlantic Ocean (34°-55°S). This is the first record of this species, which was previously known for tropical waters (Brazil, 16°S), in the temperate waters of the South American Atlantic Ocean. Possible reasons for its appearance so far south are discussed

Keywords : Eutonina scintillans; Leptomedusae; first record; temperate waters; southwestern Atlantic Ocean.
