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

Abstract

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.

Centrorhynchus spp. (Acanthocephala) in South America: new anuran record and checklist of vertebrate hosts

“…The checklist presented here has expanded the information of previously published lists ( Travassos, 1926 ; Smales, 2007a , b ; Ávila & Silva, 2010 ; Lunaschi & Drago, 2010 ; Smales, 2013 ; Campião et al, 2014 ; Fugassa, 2015 ; Cuellar et al, 2022 ), as it has brought together new records for South America, where birds are the definitive hosts most frequently parasitized by Centrorhynchus spp. The reports of cysthacanths of Centrorhynchus sp.…”

Checklist of parasites associated with ʻreptiles’ in Northeast Brazil

“…For host taxonomy we followed Costa et al (2021) and the taxonomy of parasites we followed Anderson et al (2009) for nematodes, Christoffersen & De Assis (2013) for pentastomids, Amin (2013) for acanthocephalans, Lunaschi & Drago (2007) and Fernandes & Kohn (2014) for trematodes, Paredes-León et al . (2008) and Cuellar et al (2022) for cestodes, Barros-Battesti et al (2006), Martins et al (2010), Andreotti et al (2016), Nava et al (2017) for ticks and varied literature for mites (Paredes-León et al ., 2008; Mendoza-Roldan et al, 2020). For all groups of parasites, the SiBBr (Information System on Brazilian Biodiversity, n.d.) database was also consulted.…”
