“…The original record (as Clinostomum dimorphum Diesing, 1850) was made as a parasite of Ardea cocoi . According to Lent & Freitas (1937) the species was transferred to Ithyoclinostomum by Witenberg (1925), but as a generic diagnosis was not provided, Lent & Freitas formally described the genus for the first time. Since it was first described, I. dimorphum has also been reported as a parasite of Ardea alba (Linnaeus, 1758), Nycticorax nycticorax (Linnaeus, 1758) and Tigrisoma lineatum (Boddaert, 1783) (see Benigno et al , 2014; Fernandes et al , 2015).…”

The family Clinostomidae Lühe, 1901 contains 29 species allocated to seven genera, of which Clinostomum Leidy, 1856 is the most diverse, with c. 14 valid species. The diversity of Clinostomum has been assessed, combining morphological and molecular data. The genetic library for species in this genus has increased steadily, although there is little or no information for the other genera included in the family. Molecular phylogenetic relationships among the genera of clinostomids have not been assessed, and their classification is still based on morphological traits. The monotypic Ithyoclinostomum was described from a fish-eating bird in Brazil, and its metacercariae have been found in several locations in South America, parasitizing erythrinid freshwater fishes. We collected unusually large metacercariae from the body cavity of cichlids in several locations across Middle America. These metacercariae exhibited some resemblance to Ithyoclinostomum, although several differences prevent their inclusion in Ithyoclinostomum dimorphum, casting doubt on their taxonomic identification. The main objective of this paper was to characterize the metacercariae collected in cichlids using both morphology and molecular data from three molecular markers, and to assess the molecular phylogenetic relationships among the genera of Clinostomidae to establish the position of the newly generated sequences. We took a conservative position and tentatively placed the metacercariae as belonging to Ithyoclinostomum.

“…The brown-nosed coati Nasua nasua (Linnaeus, 1766) Storr, 1780 (Procyonidae) is a medium-sized carnivore abundant in many regions of South America [1, 5], especially in the Pantanal wetlands region [4, 5]. A few species of acanthocephalans have been reported infecting N. nasua, including Oncicola luehei [19, 17] in Pará, São Paulo, Minas Gerais, Mato Grosso, and Mato Grosso do Sul States [11, 13, 19, 23] and Neoncicola potosi [13, 17] in Foz de Iguaçú, Paraná State [15].…”

IntroductionPachysentis comprises 10 species, which have been reported parasitizing mammals in Africa and the American continent. However, species of Pachysentis have not been described in brow-nosed coatis. Pachysentis lauroi n. sp. (Oligacanthorhynchidae: Acanthocephala) is described from the brown-nosed coati Nasua nasua (Linnaeus, 1766) Storr, 1780 (Procyonidae: Carnivora) in the Brazilian Pantanal wetlands of the Mato Grosso do Sul State, Brazil. MethodsSpecimens were studied using light and scanning electron microscopy. ResultThe new species is distinguished from other species of Pachysentis by the number of hooks in each longitudinal row (12 rows of 4 hooks, total of 48 hooks), presence of barbs on all hooks, and the organization of the cement glands. Notes on the genus Pachysentis [14] and a key to its species are provided. Critical comments on some species with a dubious diagnosis and questionable or missed key taxonomic characteristics are also reviewed. We also discuss the zoogeography of the members of the genus.
