Proteocephalids are a cosmopolitan and diverse group of tapeworms (Cestoda) that have colonized vertebrate hosts in freshwater and terrestrial environments. Despite the ubiquity of the group, key macroevolutionary processes that have driven the group's evolution have yet to be identified. Here, we review the phylogenetic relationships of proteoceph...
Neotropical fish amphistomes represent a highly diverse group within the Paramphistomoidea, with wide distribution across major South American hydrological drainages. However, the limited molecular characterization of these taxa has impeded a comprehensive assessment of their evolutionary relationships and the systematic relevance of morphological...
Parasitism is ubiquitous and one of the most successful lifestyles on Earth, with more than 200 independent transitions from non-parasitic ancestors considered only in the kingdom Animalia [...]
Despite recent advances in the molecular knowledge of amphistome trematodes, most genera known from fish remain to be genetically characterized. This is the case for Kalitrema, a genus of the speciose family Cladorchiidae and the type of Kalitrematinae. The type and only species of this genus, Kalitrema kalitrema Travassos, 1933, was originally pro...
An analysis of papers published in the last seven
years shows that particular attention has been
paid to taxonomic revisions of species groups
and individual genera, most of which are poorly
known.
Echinostoma paraensei , described in Brazil at the end of the 1960s and used as a biological model for a range of studies, belongs to the ‘ revolutum ’ complex of Echinostoma comprising species with 37 collar spines. However, molecular data are available only for a few isolates maintained under laboratory conditions, with molecular prospecting base...
This study assesses parasitism and pathologic manifestations in free-ranging Crotalus durissus terrificus. A total of 96 rattlesnakes from the State of Minas Gerais (southeast Brazil) were necropsied between September 2019 and February 2020. Granulomatous gastritis affected 48% (46 of 96) of the snakes evaluated, which were associated with the asca...
Despite the recent advances raised in the molecular era to the taxonomic knowledge of species of the family Cli-nostomidae, especially those belonging to the specious Clinostomum, some groups of these vertebrate parasites remain poorly studied. This is the case of species of the enigmatic genus Ithyoclinostomum Witenberg, 1926, until recently monot...
Despite being the two most recorded species of Physaloptera from lizards in the Americas, P. retusa and P. lutzi are either incompletely described or have accumulated inaccurate morphological data through the years. Here, we redescribe both species from Tropidurus torquatus in the State of Minas Gerais, Brazil, including evaluation of specimens fro...
The proteocephalid genus Pseudoendorchis (Cestoda: Onchoproteocephalidea) has recently been proposed to accommodate seven species/species-level lineages of tapeworm parasites of catfishes (Siluriformes) in the Neotropical region, based on integration of genetic information, and morphological and ecological data. Its members are typified by having a...
The yellow-billed cuckoo, Coccyzus americanus, is a threatened passerine bird native to North America that migrates to overwinter in South America. Although migratory birds have drawn broad attention, given their assumed role in the long-distance dispersal of parasites, studies on the helminth fauna of this cuculid are scarce. In the present study,...
Although Echinostoma robustum (currently a synonym of E. miyagawai ) was reported in the Americas based on molecular data, morphological support on adult parasites is still required. Herein, a new species of Echinostoma is described based on worms found in a chicken from Brazil. Molecular phylogenetic analyses based on 28S (1063 bp), ITS (947 bp) a...
While much attention has been paid to vector-borne filariasis, diseases that threaten millions of people in tropical and subtropical countries, the literature on host–parasite associations and transmission strategies of filarial nematodes in wildlife is scarce. Here, we report the co-occurrence of chigger mites ( Eutrombicula alfreddugesi ) and onc...
Tapeworms (Cestoda: Proteocephalidae) are the dominant component of communities of intestinal parasites in pimelodid and other catfishes (Siluriformes) from South America. Even though these parasites have been studied intensively over more than one century, molecular taxonomy and phylogenetics have questioned their morphology-based classification,...
Ophiotaenia echidis n. sp. (Cestoda: Proteocephalidae) is described from the intestine of one of the world's deadliest snakes, the saw-scaled viper Echis carinatus sochureki Stemmler (Ophidia: Viperidae) in the United Arab Emirates. The new species differs from other species of the non-monophyletic Ophiotaenia by the position of testes in two longi...
Amphistome species belonging to the genus Catadiscus are poorly studied intestinal trematodes found primarily in Neotropical anurans. Herein, developmental stages of an amphistome species found during herpetological and malacological surveys in a temporary marsh pond from Brazil were subjected to morphological (light and scanning electron microscop...
Proteocephalid tapeworms are the dominant group of endoparasites in siluriform
catfishes in South America, but their interrelationships and actual diversity remain
poorly understood. Molecular prospecting of proteocephalids found in pimelodid
and other catfishes, especially in Pimelodus spp., along with thorough morphological
evaluation, revealed h...
Zygocotyle lunata inhabits the caecum of birds and mammals from the American continent. This amphistome parasite is easily maintained in the laboratory and serves as a model organism in life-cycle studies, but it has seldom been studied using molecular data. Neither the position of Z. lunata in the superfamily Paramphistomoidea nor the monophyly of...
Proteocephalid tapeworms (Cestoda) are one of the dominant groups of intestinal parasites of Neotropical catfishes (Siluriformes), especially pimelodids (de Chambrier et al. 2015). The long and convoluted taxonomic history of species of Chambriella Rego, Chubb & Pavanelli, 1999 has been disentangled only recently by Alves et al. (2017). These autho...
Species of two monotypic genera, Ephedrocephalus Diesing, 1850 and Zygobothrium Diesing, 1850 (Cestoda: Proteocephalidae), parasites of one of the most basal members of the catfish family Pimelodidae, the redtail catfish, Phractocephalus hemioliopterus, in the Neotropical Region, are redescribed based on the evaluation of type specimens and newly c...
The cestode genus Goezeella Fuhrmann, 1916 is reviewed on the basis of taxonomic evaluation of type and
newly collected material from pimelodid and heptapterid catfishes (Siluriformes) in the Amazon River basin, South America, and its generic diagnosis is amended. The genus is typified by the exclusively ventral position of the cortical vitelline f...
A new genus of dactylogyrid monogeneans (Ancyrocephalinae), Paracosmetocleithrum n. gen., is erected to accommodate P. trachydorasi n. sp. from Trachydoras paraguayensis (Siluriformes: Doradidae) in the Upper Paraná River basin, Brazil. The new genus differs from Neotropical dactylogyrids in the presence of a well-developed ornamentation in the mid...
Synbranchiella gen. n. is proposed to accommodate Synbranchiella mabelae sp. n. (Proteocephalidae: Monticelliinae) from the intestine of the marbled swamp eel Synbranchus marmoratus Bloch, in the River Colastiné, a tributary of the middle River Paraná in Argentina. The new genus is placed in the Monticelliinae because of the cortical position of th...
As part of a complex revision of proteocephalid cestodes parasitic in freshwater bony fishes of the Neotropical Region, the genus Chambriella Rego, Chubb & Pavanelli, 1999 is redefined based on detailed examination of type-specimens and newly collected material of both nominal species of the genus. This examination revealed that the type-species C....
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 di...
