“…Although congeneric species P. nattereri is native to the Amazon and Paraná river basins, it can be found in several South American countries (Froese & Pauly 2019). Its endoparasite fauna was investigated by Rego & Eiras (1989), Rego & Pavanelli (1990), Moravec (1998), Pavanelli et al (2004), Thatcher (2006, Barros et al (2006Barros et al ( , 2010, Vieira et al (2010Vieira et al ( , 2011, Morais et al (2011Morais et al ( , 2019, Benigno et al (2012), Cárdenas et al (2012), Vicentin et al (2013) and Brito-Junior & Tavares-Dias (2018). The current study has investigated the endoparasite fauna of fish species P. piraya because the few studies carried out on this topic (Travassos et al 1928, Moreira et al 1994, Brasil-Sato 2003, Moravec et al 2008, Santos et al 2009, Monteiro et al 2016) have indicated that this piranha species is a potential host for peculiar endoparasite fauna in Três Marias reservoir, upper São Francisco river, state of Minas Gerais, Brazil.…”

Ten endoparasite species found in Pygocentrus piraya, which is a piranha species native to São Francisco river, were collected from 108 fi sh caught in Três Marias reservoir in 2004 and 2005, namely: Digenea -Austrodiplostomum sp. (metacercariae); Eucestoda -Proteocephalidae gen. sp. (plerocercoids); and Nematoda -Procamallanus (Spirocamallanus) inopinatus, Cystidicoloides fi scheri and Capillostrongyloides sentinosa (adults); Spinitectus rodolphiheringi (juvenile); Hysterothylacium sp., Contracaecum sp. Type 1 , Spiroxys sp. and Goezia sp. (larvae). In helminth fauna, P. (S.) inopinatus has shown higher prevalence and dominance. Fish sex has infl uenced the prevalence of Hysterothylacium sp., which was higher in female specimens. Longer total length of fi sh has positively infl uenced the abundance of C. sentinosa and Hysterothylacium sp.. The rainy season has favored parasitic indices, mainly P. (S.) inopinatus abundance, as well C. sentinosa and Hysterothylacium sp. prevalence and abundance. There were co-occurrences between adult and some larval nematodes. Endemic piranhas, as well as fi nal hosts, are important intermediate and/or paratenic hosts, given the relevant number of larvae (proteocephalideans and nematodes) of heteroxene cycle found in them. Proteocephalidae gen. sp., C. sentinosa, Hysterothylacium sp., Contracaecum sp. Type 1 , Goezia sp. and S. rodolphiheringi are new records parasitizing P. piraya in São Francisco basin.

Using mitochondrial and ribosomal DNA sequences to test the taxonomic validity of Clinostomum complanatum Rudolphi, 1814 in fish-eating birds and freshwater fishes in Mexico, with the description of a new species

et al. 2013

The taxonomic history and species composition of the genus Clinostomum has been unstable. Two species, Clinostomum complanatum Rudolphi, 1814 and Clinostomum marginatum Rudolphi, 1819, have been particularly problematic and its validity has been disputed for nearly 200 years. In this paper, we have made use of an integrative taxonomy approach, and we used, in first instance, DNA sequences of two genes (cox1 and ITS) to test the validity of C. complanatum, a species apparently widely distributed in Mexico and to link the metacercariae and adult forms of the recognized species of Clinostomum. Combining molecular data with morphology, host association, and geographical distribution, we searched for the potential existence of undescribed species. A new species of Clinostomum is described based on adults found in the mouthy cavity of three species of fish-eating birds as well as in metacercariae found in freshwater and estuarine fishes. A few morphological characteristics distinguish the new species from other congeners even though reciprocal monophyly in a phylogenetic tree based on maximum-likelihood and Bayesian analysis, genetic divergence, and a multivariate analysis of variance and a principal component analysis of 18 morphometric traits for adults and metacercariae demonstrates the validity of the new species. Based on our results, it seems that C. complanatum is not currently distributed in Mexico, although this requires further verification with a more thoroughful sampling in other areas of the country, but it is plausible to support the hypothesis that C. marginatum is the American form, as previously suggested by other authors.
