Lironeca desterroensis sp. nov. (Isopoda, Cymothoidae) from the gills of a marine fish, Cetengraulis edentulus Cuvier, of Santa Catarina Island, Brazil

Abstract

Lironeca desterroensis sp. nov. (Isopoda, Cymothoidae) is described on the basis of 105 females and three males taken from the gill chambers of the marine fish, Cetengraulis edentulus (Cuvier,1829), obtained near Santa Catarina Island, Brazil. The new species resembles Lironeca redmanni Leach, 1818, in size and general appearance but differs from that species in a number of important respects. In the new species, the pleotelson is larger, the pleonites are laterally produced, the uropods have elongate and slender rami and the larval stage (Pullus II) has a prominent frontal projection

Occurrence of isopods ectoparasites in marine fish on the Cotegipe Bay, north-eastern Brazil

“…These results match other findings from the literature, where some studies of isopod parasites in other Brazilian coastal localities, showed that there were 75% prevalence of Livoneca redmanni in December and 44% for Rocinela signata in July for the host Scomberomorus brasiliensis (Lima et al, 2005). Other studies found 20% for Cymothoa catarinensis for the host Menticirrhus litoralis and 13% for Cymothoa excisa for the host Micropogonias furnieri (Thatcher et al, 2003a), and also the parasitism of Lironeca redmanni on Cetengraulis edentulus showed the prevalence of 17% (Thatcher et al, 2003b).…”
