Associações entre medusas (Cnidaria) e isópodos (Crustacea) nos litorais do Paraná e Santa Catarina, Brasil

O presente trabalho refere-se a associacoes entre isopodos e macromedusas nos litorais do Parana e de Santa Catarina, sendo este o primeiro registro. Quatro especies de Isopoda foram encontradas: 1. Nerocila fluviatilis Schioedte & Meinert, 1881 e 2. Cymothoa catarinensis Thatcher et al. 2003 (Cymothoidae) parasitando, respectivamente Chiropsalmus quadrumanus (Muller, 1859) (Cubozoa) e Chrysaora lactea Eschscholtz, 1829 (Scyphozoa: Semaeostomeae); 3. Ancinus brasiliensis Castro, 1959 (Sphaeromatidae) inquilino de C. quadrumanus e 4. Synidotea marplatensis Giambiagi, 1922 (Idotheidae) associada a tres especies: C. lactea, Lychnorhiza lucerna Haeckel, 1888 (Scyphozoa: Rhizostomeae) e Olindias sambaquiensis Muller, 1861 (Hydrozoa: Limnomedusae). Associations between medusae (Cnidaria) and isopods (Crustacea) at the littoral of Parana and Santa Catarina State, Brazil Abstract The present study comments on isopods found associated on macromedusae at the littorals of the Parana and Santa Catarina States, Southern Brazil. This is the first communication of these interactions. Four species were found: 1. Nerocila fluviatilis .Schioedte & Meinert, 1881 and 2. Cymothoa catarinensis Thatcher et al. 2003 (Cymothoidae) parasite respectively Chiropsalmus quadrumanus (Muller, 1859) (Cubozoa) and Chrysaora lactea Eschscholtz, 1829 (Scyphozoa: Semaeostomeae); 3. Ancinus brasiliensis Castro, 1959 (Sphaeromatidae) living on C. quadrumanus and Synidotea marplatensis Giambiagi, 1922 (Idotheidae) on C. lactea, Lychnorhiza lucerna Haeckel, 1888 (Scyphozoa: Rhizostomeae) and Olindias sambaquiensis Muller, 1861 (Hydrozoa: Limnomedusae). Resume Le present travail s’agit du premier raport des associations entre les isopodes et les meduses dans le cotes du Parana et Santa Catarina. Quatre especes d’Isopoda sont etes trouves: 1. Nerocila fluviatilis Schioedte & Meinert, 1881 et 2. Cymothoa catarinensis Thatcher et al. 2003 (Cymothoidae) qui parasitaient, respectivement Chiropsalmus quadrumanus (Muller, 1859) (Cubozoa) et Chrysaora lactea Eschscholtz, 1829 (Scyphozoa: Semaeostomeae); 3. Ancinus brasiliensis Castro, 1959 (Sphaeromatidae) parasite de C. quadrumanus e 4. Synidotea marplatensis Giambiagi, 1922 (Idotheidae) associee a trois especes: C. lactea, Lychnorhiza lucerna Haeckel, 1888 (Scyphozoa: Rhizostomeae) et Olindias sambaquiensis Muller, 1861 (Hydrozoa: Limnomedusae).
