“…The species from turtles and fishes can only be distinguished based on the size of spicules, gubernacule, and the number of caudal papillae ( Costa, 1960 , 1961 ; Costa et al, 1968 ). Klossinemella conciliatus has also been reported in the stomachs of yellow-spotted Amazon River turtles ( Podocnemis unifilis ) from Loreto and Ucayali in Peru ( Salízar & Sanchez, 2004 ). The mouth structures and caudal papillae are the main features of this genus ( Moravec & Thatcher, 1997 ; Costa, 1961 ).…”

“…Nematophila grandis has been described in several aquatic turtles in Central and South America ( Dyer & Carr, 1990 ; Lombardero & Moriena, 1977 ; Sánchez et al, 2006 ; Salízar & Sanchez, 2004 ). In Brazil, it has been described in the Scorpion mud turtle ( Kinosternon scorpioides scorpioides ) ( Alho, 1964 ) and Geoffroy’s toadhead turtle ( Phrynops geoffroanus ) ( Fonseca et al, 2021 ).…”

The big-headed Amazon River turtle, Peltocephalus dumerilianus, is endemic to the Orinoco and Amazon River basins. It is a food source for local communities, often unsustainably. Knowledge about P. dumerilianus’ parasitological fauna and host-parasite relationships is limited. Thus, ecological aspects of gastrointestinal parasitism in this species were investigated. Helminths were found in the gastrointestinal tract of 21 turtles, morphologically identified, and infection descriptors calculated. All animals harbored helminths: nematodes Ancyracanthus pinnatifidus, Paratractis hystrix, Atractis trematophila, Klossinemella conciliatus indeterminate three Klossinemella species, and digeneans Nematophila grandis, Helicotrema spirale, and Telorchis hagmanni. The highest parasite load occurred in the large intestine, followed by the small intestine and stomach. Shell length directly correlated with parasite burden of heteroxenic helminths, with males having higher burden than females. This is the first record of A. trematophila, K. conciliatus, and T. hagmanni in P. dumerilianus, and new location record for A. trematophila, P. hystrix, N. grandis, H. spirale, and T. hagmanni. Three potentially new Klossinemella species are presented.

“…The yellow-spotted Amazon River turtle, P. unifilis is also a species that lives in a wide variety of habitats, such as rivers and lakes (Cisneros-Heredia, 2006). However, its helminth parasites have been poorly studied (Salizar & Sánchez, 2004;Sánchez et al, 2006;Tantaleán et al, 2011;Tantaleán & Forlong, 2013). Considering the high diversity of reptile hosts in Peruvian territory with very diverse regions and microclimates, it is possible that a significant number of new species may emerge in future parasitological studies.…”

A checklist of helminths associated with reptiles (Tetrapoda: Reptilia) from Peru

et al. 2022

An annotated checklist of the helminth parasites associated with reptiles from Peru is provided, as the result of a compilation of parasitological papers published between 1963 and January 2022 and records of species deposited in national and international collections. The list provides data on hosts, developmental stage, sites of infection, geographical distribution in Peruvian territory, code of material deposited in helminthological collections, references and taxonomic notes. The database includes records of 106 different species of helminth parasites (82 nominal species and 24 taxa identified at the generic level), the majority in the adult stage. These helminth parasites come from 18 of the 25 official Peruvian regions. Nematodes have the highest richness in number of species (79 species), followed by trematodes (17 species) and cestodes (nine species). The acanthocephalans are represented by only one species. The parasites with the highest number of records were Physaloptera retusa Rudolphi, 1819 (11 hosts), Physalopteroides venancioi (Lent, Freitas & Proença, 1946) (nine hosts), Strongyluris oscari Travassos, 1923 (seven hosts), and Parapharyngodon scleratus Travassos, 1923 (five hosts), all of which are nematodes. The 106 taxa of helminth parasites have been reported infecting 55 species of reptiles in Peru, distributed in 34 genera and 14 families. The reptile species harbouring the highest number of helminth parasites are the yellow-footed tortoise Chelonoidis denticulatus (Linnaeus) with 18 species (three trematodes and 15 nematodes), followed by the Peru desert tegu Dicrodon guttulatum Duméril & Bibron (Teiidae) with 11 species (three cestodes and eight nematodes) and the yellow-spotted Amazon River turtle Podocnemis unifilis Troschel (Podocnemididae) with 10 species (five trematodes and five nematodes). Of the 524 species of reptiles reported in Peru, only 55 (>10%) are reported as hosts of helminths representing a small proportion considering the great variety of reptile hosts that inhabit the various tropical and subtropical geographical areas of Peru.

AbstractCricocephalus albus (Digenea: Pronocephalidae) is registered for first time in Peru in the East Pacific green turtle (Chelonia mydas agassizii). The parasites were collected during a necropsy carried out in a stranded sea turtle in the Virrilá estuary, located in the Sechura province of Piura, Peru. The specimens were studied morphologically and identified as C. albus. The current work describes C. albus, as well as the discussion of its hosts and geographic distribution.
