An exhaustive literature search supplemented by a critical examination of records made it possible to present an annotated checklist of tapeworms (Cestoda) that, as adults or larvae (metacestodes), parasitize freshwater, brackish water and marine fishes, i.e. cartilaginous and bony fishes, in South America. The current knowledge of their species diversity, host associations and geographical distribution is reviewed. Taxonomic problems are discussed based on a critical evaluation of the literature and information on DNA sequences of individual taxa is provided to facilitate future taxonomic and phylogenetic studies. As expected, the current knowledge is quite uneven regarding the number of taxa and host-associations reported from the principal river basins and marine ecoregions. These differences may not only reflect the actual cestode richness but may also be due to the research effort that has been devoted to unravelling the diversity of these endoparasitic helminths in individual countries. A total of 297 valid species, 61 taxa identified to the generic level, in addition to unidentified cestodes, were recorded from 401 species of fish hosts. Among the recognized cestode orders, 13 have been recorded in South America, with the Onchoproteocephalidea displaying the highest species richness, representing c. 50% of all species diversity. The majority of records include teleost fish hosts (79%) that harbour larval and adult stages of cestodes, whereas stingrays (Myliobatiformes) exhibit the highest proportion of records (39%) among the elasmobranch hosts. Fish cestodes are ubiquitous in South America, being mostly recorded from the Warm Temperate Southeastern Pacific (WTSP; 31%) for marine hosts and the Amazon River basin (45%) for freshwater ones. The following problems were detected during the compilation of literary data: (i) unreliability of many records; (ii) poor taxonomic resolution, i.e. identification made only to the genus or even family level; (iii) doubtful host identification; Alves et al. / ZooKeys 650: 1-205 (2017) 2 and (iv) the absence of voucher specimens that would enable us to verify identification. It is thus strongly recommended to always deposit representative specimens in any type of studies, including faunal surveys and ecological studies. An analysis of the proportion of three basic types of studies, i.e. surveys, taxonomic and ecological papers, has shown a considerable increase of ecological studies over the last decade.

“…The Argentinean silverside, Odontesthes bonariensis, is one of the most important freshwater fish for consumption and for sport fishing in the Pampas region, as well as one of the species most affected by lernaeosis (MANCINI et al, 2008a). In chronic diseases, L. cyprinacea produces serious consequences in O. bonariensis, mainly secondary bacterial infections.…”

Parasitic copepods of the family Lernaeidae are often found infesting freshwater fishes worldwide. They cause lernaeosis, a disease that can lead to serious pathogenic effects on their fish hosts. The most common lernaeid is the Lernaea cyprinacea, which has been widely introduced through importation of tropical fishes, e.g. cyprinids. In South America, it is one of the most common parasites both in wild and in farmed fish in the central region of Argentina. The silverside Odontesthes bonariensis is the most important fish of the sport fisheries of Argentina and one of the fish most affected by lernaeosis. Six specimens of copepods were collected from 30 specimens of O. bonariensis collected in a Pampean shallow lake (33°25'28"S 62°53'56"W) of Córdoba (Argentina). The 28S rRNA gene of L. cyprinacea was amplified by means of PCR to obtain the 28S rDNA sequence. The sequence obtained of this parasite from Argentina showed high genetic similarity with those from various geographical origins. The present study provided molecular characterization of L. cyprinacea in South America for the first time.

“…Although silversides species are widely distributed, reports of parasites from wild fishes are scarce and scattered (Carballo, 2008;Carballo, Laurenti, & Cremonte, 2011;Carballo, Navone, & Cremonte, 2011;Carballo, Cremonte, Navone, & Timi, 2012;Drago, 2012;Mancini, Rodríguez, Prosperi, Salinas, & Bucco, 2006;Mancini et al, 2008;Ortubay, Semenas, Úbeda, Quaggiotto, & Viozzi, 1994). Besides publications on rearing silversides, there is no published information on their parasites (Tanzola, Semenas, & Viozzi, 2009).…”

This study presents new geographical distribution records for the macroparasites of the marine Odontesthes nigricans (Richardson, 1848) (89 wild specimens), and for the freshwater silversides Odontesthes bonariensis (Valenciennes, 1835) (43 wild and 108 cultured specimens), and Odontesthes hatcheri (Eigenmann, 1909) (183 wild specimens) from Argentina. These data represent records of 12 parasite taxa for O. nigricans, 8 for O. bonariensis, and 19 for O. hatcheri, which include digeneans, monogeneans, cestodes, nematodes, acantocephalans, mollusks, copepods, and branchiurans. For cultured O. bonariensis, the records of the present study correspond to the first reports of parasites in the literature. This work provides also data on site of infection, parasite load, and development stages for the parasite species.
