“…Previous studies on the helminths of D. aurita have primarily been taxonomic descriptions and records of occurrence (Thatcher, 2006; Chagas-Moutinho et al ., 2014). There have been a few studies on helminth community structure in marsupial species (Antunes, 2005; Jiménez et al ., 2011; Byles et al ., 2013). This study describes the species composition and analyses the structure of the helminth metacommunities of D. aurita at both infracomunity and component community levels.…”

Among the Brazilian marsupials, the species of the genus Didelphis are the most parasitized by helminths. This study aimed to describe the species composition and to analyse the helminth communities of the Atlantic Forest common opossum Didelphis aurita at infracommunity and component community levels using the Elements of Metacommunity Structure Analysis, considering peri-urban, sylvatic and rural environments in the state of Rio de Janeiro, Brazil. Seventy-three specimens of D. aurita were captured during the study. Fourteen species of helminths were collected: nine of the phylum Nematoda (Trichuris minuta, Trichuris didelphis, Globocephalus marsupialis, Heterostrongylus heterostrongylus, Travassostrongylus orloffi, Viannaia hamata, Aspidodera raillieti, Cruzia tentaculata and Turgida turgida); four of the phylum Platyhelminthes (three species of Trematoda, Duboisiella proloba, Brachylaima advena and Rhopalias coronatus, and one species of the class Cestoda); and one species of the phylum Acanthocephala (Oligacanthorhynchus microcephalus). More than 95% of the animals were infected with parasites. The most abundant parasite species were V. hamata, T. turgida, C. tentaculata and T. orloffi. The nematodes T. turgida, C. tentaculata and A. raillieti were the most dominant species in the three environments. The analysis of the metacommunity structure indicated a structured pattern as a function of the environmental gradient, but only when all localities were considered together. At the infracommunity and component community levels, quasi-nested and nested structures with stochastic species loss were observed, respectively. The results indicate that the settlement of helminth species in the opossums can be attributed to the heterogeneity among individual hosts in relation to their exposure to parasites and to extrinsic factors, which vary among habitats, considering a regional scale. On a local scale, the characteristics of this host species may promote homogenization among individual hosts in terms of their exposure to the helminths. This study constitutes a new host record for the species G. marsupialis and T. didelphis and represents a pioneering investigation of the helminth metacommunity of a Neotropical marsupial.

“…Pterygodermatites ( P. ) mexicana can be easily differentiated from P. ( Paucipectines ) elegans in the position of the stoma, which is apical in the latter [ 13 ] and dorsal in the species herein described. In addition, P. ( Paucipectines ) elegans has been reported exclusively in South America infecting both bats and marsupials [ 2 , 13 , 14 ].…”

A new species of nematode, Pterygodermatites (Pterygodermatites) mexicana n. sp., is described based on specimens recovered from the intestine of the gray sac-winged bat, Balantiopteryx plicata (Chiroptera, Emballonuridae), from the Biosphere Reserve “Sierra de Huautla” in the state of Morelos, Mexico. This is the second species in the genus described from bats in the New World, since most of the rictaluriids reported in these hosts belong to the closely related genus Rictularia Froelich, 1802. However, members of Rictularia possess only a single oesophageal tooth at the base of the buccal capsule, whereas in the current nematodes three conspicuous oesophageal teeth are present. They are therefore included in Pterygodermatites Wedl, 1861. The new species is characterized by the presence of 23 small denticles on the periphery of the buccal capsule and by the presence of 40 and 66 pairs of cuticular processes in males and females, respectively. Additionally, males possess 3–4 ventral precloacal fan-like processes, and the cuticular processes of females are divided into 40 pairs of comb-like and 26 pairs of spine-like processes; the vulva opens on the level of approximately pair 40. The dorsally directed stoma and the 40 prevulvar cuticular processes makes it difficult to place the species in any of the subgenera present in the New World, yet characters correspond with the diagnosis of Pterygodermatites (Pterygodermatites) in the Mediterranean region and North Africa.

“…Most of them were carried out for large marsupials, such as Didelphis marsupialis (Freitas et al 2022), Didelphis aurita (Costa-Neto et al 2019), Didelphis albiventris (Cirino et al 2022), Metachirus myosurus (Cirino et al 2020) and Philander opossum (Ramírez-Cañas et al 2019). For the genus Marmosa, there is only one study comparing the helminth structure of two sympatric species of this genus (M. demerarae and M. murina) in French Guiana (Byles et al 2013).…”

Marmosa constantiae is a species of marsupial, restricted to the central portion of South America. In Brazil, it is restricted to the states of Acre, Amazonas, Mato Grosso, Paraná and Rondônia. However, there is no study of the helminth fauna or helminth community structure for this marsupial. The aims of this study were to describe the species composition and to analyse the structure of the helminthic community of M. constantiae at the infracommunity level in an area of the Amazon Arc in Sinop, north of the state of Mato Grosso, Brazil. Parasites were searched in 53 specimens of this marsupial, among which 44 were infected with at least one helminth species. Parasitic helminths were counted and identified. Nine species were collected: seven nematodes, one cestode and one acanthocephalan. The most abundant species were Gracilioxyuris agilisis, Travassostrongylus scheibelorum, Pterygodermatites sinopiensis and Subulura eliseae. These species were the only dominants in the component community. No significant differences were observed in the abundance and prevalence of helminths between male and female hosts. Host body size significantly influenced the helminth abundance in males. The pattern of community structure considering the infracommunities in this locality indicated more species replacement than species loss along the environmental gradient. This is the first study to analyse the helminth fauna and the helminth community structure of M. constantiae.
