“…Using an integrative approach that combined morphology and genetic information, Hernández-Mena et al (2016) uncovered the non-monophyly of the Macroderoidiidae. Subsequently, the validity of the new family was upheld by several studies that confirmed the monophyly of the family Alloglossidiidae (Sokolov & Shchenkov, 2017; Kasl et al , 2018; Davies et al , 2021).…”

“…However, some species exhibit an abbreviated life-cycle where the definitive host is lost through a progressive event of facultative precocious development, leading to an obligate two-host pattern with a crustacean as the final host, and finally a host switching event from the crustaceans to leeches as definitive hosts (Kasl et al , 2018). On the other hand, Magnivitellinum is represented by only three species parasitizing characiform and siluriform fishes distributed in the Neotropical biogeographical region across the Americas, namely Magnivitellinum simplex Kloss, 1966 parasitizing several species of characids and one species of siluriform (Kohn et al , 2007; Pérez-Ponce de León et al , 2007; Davies et al , 2021); Magnivitellinum corvitellinum Lacerda, Takemoto & Pavanelli, 2009 parasitizing Hoplosternum littorale (Hancock) (Siluriformes); and Magnivitellinum saltaensis Davies, Liquín, Lauthier, Párraga, Saravia, Davies & Ostrowski de Núñez, 2021 parasitizing Psalidodon endy (Mirande, Aguilera & Azpelicueta) (Characiformes). Interestingly, the three species have been reported from Argentinian freshwaters (see Lunaschi, 1989; Ostrowski de Núñez et al , 2017; Davies et al , 2021).…”

Description of Diegoglossidium maradonai n. g. and n. sp. (Digenea: Alloglossidiidae) through an integrative taxonomy approach, with an amended diagnosis of the family

This paper describes Diegloglossidium maradonai n. g., n. sp. a parasite of the intestine of Hoplosternum littorale (Hancock) from La Plata River basin. The new genus is morphologically similar to members of Alloglossidiidae and Macroderoidiidae although they also share some traits observed in both families. Those families can be differentiated from each other by the combination of morphological features, including the density and distribution of the tegumental spines, the distribution of the vitelline follicles and the extent of the post-testicular space. The molecular analyses based on the large subunit of the ribosomal RNA gene, and the internal transcribed spacer (ITS) regions including ITS1, 5.8S and ITS2 unequivocally place the new genus in the family Alloglossidiidae which is amended based on new observed features. Diegoglossidium n. g. is characterized by a combination of characteristics, being most notably the presence of a deeply lobed ovary. Lastly, the geographical distribution and host associations of the two closely related Neotropical genera of Alloglossidiidae: Magnivitellinum and Diegoglossidium are discussed, and the host and distribution range of Magnivitellinum saltaensis is expanded into Argentina.

A checklist of larval Digenea (Platyhelminthes: Trematoda) in molluscs from inland waters of Argentina: one hundred years of research

et al. 2022

View full text Add to dashboard Cite

A checklist of larval digeneans parasitising molluscs from inland waters of Argentina is presented here. Based on the bibliographical survey of 113 scientific articles and nine theses published between 1930 and 2021, 213 digeneans were found, which were distributed within 13 superfamilies and 35 families. The parasites were identified in 102 locations, encompassing eight of the sixteen biogeographical provinces in Argentina. Digeneans were found in 34 mollusc species (31 gastropods and three bivalves) belonging to 17 genera. The available data are presented for each digenean species, and included host information, localities, prevalence values, type of habitat, life cycle information (natural or experimental host), and information on material and genetic sequences deposited in repositories. Only 21.1% of individuals were identified to species level, and 8.5% to genus level. In addition, the genetic sequences of only 10 species (4.7%) were available at GenBank. This survey constitutes the first checklist of parasitic helminths in molluscs from inland waters of Argentina.

Astyanax mexicanushas repeatedly colonized cave environments, displaying evolutionary parallelisms in many troglobitic traits. Despite being a model system for the study of adaptation to life in perpetual darkness, parasites infecting cavefish are practically unknown. In this study, we investigated the macroparasite communities of 18 cavefish populations from independent lineages and compared them with the parasite diversity of their sister surface fish populations, with the aim of better understanding the role that parasites play in the colonization of new environments. Thirteen parasite taxa were found in cavefish populations, including a subset of 10 of the 27 parasite taxa known for the surface populations. Parasites infecting the cavefish belong to five taxonomic groups: trematodes, monogeneans, nematodes, copepods, and acari. Monogeneans are the most dominant group, found in 14 caves. Macroparasites include species with direct life cycles and some trophically-transmitted parasites, including invasive species. Surprisingly, cave vs surface paired comparisons indicate higher parasite richness in the caves. The spatial variation in parasite composition across the caves suggests historical and geographical contingencies of the host-parasite colonization and the potential evolution of local adaptations. Base-line data on parasite diversity of cavefish populations ofA. mexicanussets the ground to explore the role of divergent parasite infections under contrasting ecological pressures (cave vs. surface environments) in the evolution of cave adaptive traits.
