“…Likewise, the species of Monticellia have shown variable infection indices; for example, M. belavistensis showed P = 17% and I = 2 in the upper Paraná River (Pavanelli et al, 1994), P = 6% and I = 2.3 in the middle Paraná River (personal observation), and P = 5% and I = 1 in the Paraguay River (de Chambrier & Vaucher, 1999). In this study, M. santafesina exhibited low infection indices, P = 9% and I = 1.…”

Another species previously placed in Monticellia, M. megacephala Woodland, 1934, has recently been accommodated in Lenhataenia de Chambrier & Scholz, 2008, as L. megacephala, whereas M. diesingii (Monticelli, 1891) and M. macrocotylea (Monticelli, 1892) are considered species inquirendae (de Chambrier & Vaucher, 1999;Rego et al, 1999;Gil de Pertierra, 2004).…”

“…The species of Monticellia are mainly distributed in South America, where they parasitise siluriform (seven pimelodids and one doradid) and characiform (one acestrorhynchid and one characid) fishes (Woodland, 1933(Woodland, , 1935Rego et al, 1974;Pavanelli et al, 1994;de Chambrier & Vaucher, 1997Gil de Pertierra, 2004;Scholz et al, 2008). It is worthwhile noting that one species has also been described from Mexico, at the northern limit of the Neotropical region (Scholz et al, 2001).…”

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.

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.

Keys to genera of cestodes in South American freshwater teleost fishes are provided, with diagnoses of genera and short descriptions of species. Two new genera are proposed, Chambriella gen.n. for Goezeella agostinhoi Pavanelli & Santos, 1992 and G paranaensis Pavanelli & Rego, 1989, and Brooksiella gen.n. for Amphoteromorphus praeputialis Rego, Santos & Silva, 1974. Nomimoscolex magna Rego, Santos & Silva, 1974, previously species inquirenda, is transferred to the genus Proteocephalus Weinland, 1858. Goezeella nupeliensis Pavanelli & Rego, 1989 is considered a species inquirenda. Species and host lists are included
