“…The host–parasite relationship is an important parameter in the study of animal communities, as such relationships affect population dynamics and community structure (Rocha et al , 2000; Anjos et al , 2005; Almeida et al , 2009). The helminth fauna of lizards in South America has received greater attention in recent years, with many records of new hosts and localities as well as the description of new species (Goldberg et al , 2004; Bursey et al , 2005a, b; Durette-Desset et al , 2006; Bursey & Goldberg, 2007; Vrcibradic et al , 2008; Ávila & Silva, 2010). Nevertheless, studies on helminth communities and ecological aspects of host–parasite relationships remain scarce in the literature (Rocha & Vrcibradic, 2003; Anjos et al , 2005) and greater knowledge on the parasitological and ecological features of different lizard species is needed.…”

Studies focusing on communities of helminths from Brazilian lizards are increasing, but there are many blanks in the knowledge of parasitic fauna of wild fauna. This lack of knowledge hampers understanding of ecological and parasitological aspects of involved species. Moreover, the majority of research has focused on parasitic fauna of lizards from families Tropiduridae and Scincidae. Only a few studies have looked at lizards from the family Leiosauridae, including some species of Enyalius. This study presents data on the gastrointestinal parasite fauna of Enyalius perditus and their relationships with ecological aspects of hosts in a disturbed Atlantic rainforest area in the state of Minas Gerais, south-eastern Brazil. Two nematode species, Oswaldocruzia burseyi [(Molineidae) and Strongyluris oscari (Heterakidae) were found. Nematode species showed an aggregated distribution in this host population, with O. burseyi being more aggregated than S. oscari. The present study extends the range of occurrence of O. burseyi to the Brazilian continental area. IntroductionThe host -parasite relationship is an important parameter in the study of animal communities, as such relationships affect population dynamics and community structure (Rocha et al. The genus Enyalius Wied, 1821 is comprised of nine species (Sociedade Brasileira de Herpetologia, 2010) of diurnal, insectivorous lizards (Sousa & Cruz, 2008;Barreto-Lima, 2009) well distributed throughout different biomes in Brazil, such as the Atlantic rainforest (Etheridge, 1969;Vanzolini, 1972Vanzolini, , 1974Jackson, 1978), Amazon (Á vila-Pires, 1995;Vitt et al., 1996), Caatinga (semi-arid brush) and Cerrado (savanna-like vegetation) (Bertolotto et al., 2002;Rodrigues et al., 2006). Despite the wide distribution of Enyalius, few studies have addressed its helminth fauna and parasite ecology (Vicente et al., 1993;Durette-Desset et al., 2006;Sousa et al., 2007;Vrcibradic et al., 2007Vrcibradic et al., , 2008.

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

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.

“…Papuascincus stanleyanus represents a new host record for M. monas and O. bakeri; Emoia pallidiceps represents a new host record for S. milnensis. Skrjabinodon derooijae and S. sheai should be added to Table I of Bursey and Goldberg (2007): S. derooijae, spicule 49-55; male tail filament 1-2 spines; egg spindleform, 1 truncate end; female tail filament 13-16 spines; S. sheai, spicule 61-73; male tail filament 4-6 spines; egg lagenoid; female tail filament 12-16 spines.…”

Skrjabinodon derooijae sp. nov. from the large intestine of Papuascincus stanleyanus (Scincidae) and Skrjabinodon sheai sp. nov. from the large intestine of Emoia pallidiceps (Scincidae) from Papua New Guinea are described and illustrated. Skrjabinodon derooijae sp. nov. and S. sheai sp. nov. represent the 27th and 28th species assigned to the genus and the 8th and 9th species from the Australo-Papuan Region. The new species differ from other species assigned to Skrjabinodon by egg and female tail morphology. The eggs of S. derooijae are spindleform with one truncate end and the female tail bears 13-16 tail spines in a defined pattern. The eggs of S. sheai are lagenoid and the female tail bears 12-16 tail spines in a random pattern. In addition to the new species, E. pallidiceps harboured Physalopteroides milnensis and P. stanleyanus harboured Mesocelium monas and Oswaldocruzia bakeri.
