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.

“…Approximately 450 fish species occur in the continental waters of Argentina (Menni, 2004;López et al, 2005), but only few have been examined for cestodes. In the Paraná River basin in Argentina, which harbours a wide variety of fish, six new proteocephalidean tapeworms have been described (Gil de Pertierra, 1995, 2003Gil de Pertierra & de Chambrier, 2000) and another seven species redescribed (Gil de Pertierra & Viozzi, 1999;Gil de Pertierra & de Chambrier, 2000;de Chambrier & Gil de Pertierra, 2002;Gil de Pertierra, 2002a, 2004Arredondo & Gil de Pertierra, 2008).…”

The proteocephalidean tapeworm Monticellia santafesina n. sp. is described from the siluriform catfish Megalonema platanum (Günther) (Siluriformes: Pimelodidae) in the Paraná River basin, Argentina. The new species is allocated to Monticellia La Rue, 1911 (Proteocephalidae: Monticelliinae) because of the cortical position of the testes, ovary, vitelline follicles and uterus, a globular scolex without a metascolex and uniloculate suckers. The new species differs from all other species of Monticellia (except for M. lenha Woodland, 1933) in possessing a vaginal canal opening anterior or posterior to the cirrus-sac. M. santafesina can be distinguished from M. lenha by the following characteristics: a larger body size; a weakly developed internal longitudinal musculature arranged in 15-35 slim bundles of muscle fibres; vitelline follicles not interrupted at the level of the cirrus-sac and vaginal canal, and with a few paramuscular and/or medullary follicles; the absence of large spinitriches on the anterior margin of the suckers; and the utilisation of Megalonema platanum (in the Paraná River basin) as its host, rather than Sorubimichthys planiceps (Spix & Agassiz) (in the River Amazon). Monticellia santafesina exhibits low values of prevalence (9%) and intensity of infection (1). Megalonema platanum was parasitised by two proteocephalidean cestodes, Rudolphiella cf. lobosa (Riggenbach, 1895) and the new species described in this paper.

Luciaella ivanovae n. g., n. sp. (Eucestoda: Proteocephalidea: Peltidocotylinae), a parasite of Ageneiosus inermis (L.) (Siluriformes: Auchenipteridae) in Argentina

Luciaella ivanovae n. g., n. sp. (Proteocephalidea: Peltidocotylinae) is proposed to accommodate a new cestode from a siluroid fish, the manduvé Ageneiosus inermis (Linnaeus) (syn. A. brevifilis Valenciennes) (Auchenipteridae) from the Colastiné River, a tributary of the Paraná River, in Argentina. The new genus is placed in the Peltidocotylinae because it has a medullary ovary with projections into the dorsal cortex, cortical vitelline follicles and testes, a cortical uterine stem, and uterine branches penetrating the medulla and usually as far as the dorsal cortex. Luciaella can be distinguished from all other peltidocotyline genera by the following combination of characters: a quadrangular scolex with four biloculate suckers, each of which has a cap-peak-like structure situated on the anterior margin; the absence of a metascolex; vitelline follicles arranged in two lateral rows which are crescent-shaped in transverse section; testes distributed in two dorsal fields connected anteriorly and sometimes posteriorly; and a vagina which is always anterior to the cirrus-sac and overlaps the convoluted vas deferens. Filiform microtriches are present on all tegumental surfaces, with short filiform microtriches on the scolex and long filiform microtriches on the proliferation zone and on both immature and mature proglottides. The diagnosis of the Peltidocotylinae Woodland, 1934 given by Rego (1994) is amended. L. ivanovae is the fourth proteocephalidean described from A. inermis and the third recorded in this fish host from Argentina.
