New records of Pegantha spp. (Hydrozoa: Narcomedusae) off Northern Brazil

Tosetto, Everton GiachiniNeumann-Leitão, SigridNogueira Júnior, Miodeli

Specimens of Pegantha laevis H.B. Bigelow, 1909 and Pegantha triloba Haeckel, 1879 were found in oceanic waters off the northern Brazilian coast. The former species is clearly distinct due to the thickness and shape of peripheral channels, while the latter is recognized mainly due to the exumbrellar furrows and long otoporpae. This study represents the first actual record of P. laevis inside the Brazilian Economic Exclusive zone, since previous reports were far away from the coast, and clarifies the presence of P. triloba off Brazil.(AU)
