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 slen… Show more
“…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).…”

Materials and MethodsThe list of parasitic crustaceans of fishes in Brazil was based on extensive search of published records. This bibliographic review of the crustacean species reported from fishes in Brazilian waters was complemented with information from the Zoological Record, Biological Abstracts, Web of Knowledge, Google Scholar, Aquatic Sciences and Fisheries Abstracts, Biological and Agricultural Index Plus and the Scopus. Data were compiled until March, 2013. In the case of parasitic copepods, only information not presented in the checklist of Copepoda parasites of fishes from Brazil by Luque and Tavares (2007) was included. The number of parasitic associations was calculated from the sum of the richness of species of parasites on each host species.The checklist follows the classification and systematic arrangement proposed by Boxshall and Halsey (2004) for Copepoda, and Young (1998) and Martin and Davis (2001) for other crustacean groups.The species of crustaceans are arranged according to taxonomic categories, within which the species are presented in alphabetical order, followed by hosts (specific name), site of infection, habitat, localities and references (between parentheses, in chronological order). In addition, the checklist also includes crustacean species identified only at the genus level and undetermined species. Crustacean names presented in the checklist follow the most recent taxonomic literature, but validity of individual taxa or reliability of their records was not critically examined by the present authors. Host species were arranged in taxonomic and then alphabetical order.The key to identification of the genera of parasitic crustaceans from fishes in Brazil has been produced on the basis of those by Delaney
