“…Moreover, the subgenus Paucipectines includes the arrangement of the caudal papillae in males (Quentin, 1969;Anderson et al, 2009). In the Americas, 17 species belonging to the subgenus Paucipectines have been reported parasitizing rodents of the families Cricetidae and Sciuridae, marsupials of the families Caenolestidae and Didelphidae, and bats of the family Molossidae as definitive hosts (Lent & Freitas, 1935;Quentin, 1967;Sutton, 1979;Chabaud & Bain, 1981;Sutton, 1984;Navone, 1989;Navone & Suriano, 1992;Ramallo & Claps, 2007;Torres et al, 2007;Jiménez & Patterson, 2012;Miño et al, 2012;Lynggaard et al, 2014). Pterygodermatites (Paucipectines) zygodontomis was described as Rictularia zygodontomis by Quentin (1967) and later transferred to Pterygodermatites by Quentin (1969).…”

Pterygodermatites (Paucipectines) zygodontomis, a nematode parasite of the small intestine of the rodent Necromys lasiurus, from Uberlândia, Minas Gerais state, Brazil, was analysed by light and scanning electron microscopy. Additionally, phylogenies were inferred from the mitochondrially encoded cytochrome c oxidase I gene (MT-CO1). Details of the helminth surface, such as the oral aperture, cephalic papillae, papillae in the posterior region of the body and longitudinal cuticular elements represented by spine-like projections and fans are presented, adding new taxonomic details. Molecular phylogenetic analysis, based on the MT-CO1, demonstrated that P. (P.) zygodontomis and Pterygodermatites (Paucipectines) jaegerskioldi form a unique evolutionary unit in accordance with the subgenus Paucipectines and corroborated their occurrence in cricetid and didelphid hosts.

“…Navone (1989) stated that dasipodids and didelphids (marsupials) established over 60 million years ago in South America and that parasitism by rictulariids must have been established before the arrival of the cricetids during the Pliocene-Pleistocene time period. Pterygodermatites (P.) spinicaudatis Navone and Suriano, 1992 was found in Microbiotheria (= australis) from Rio Negro (Navone & Suriano 1992); Pterygodermatites (P.) zygodontomys from Bolomys (= Zygodontomys) lasiurus, Graomys (= Phyllotys) grisoflavus and A. azarae and Pterygodermatites (P.) jagerskjoldi in Caluromys phillander, whose distribution extends from Southern Mexico to Northern Argentina (Lent & Texeira de Freitas 1935).…”

The aim of this study was to examine the parasitic remains that were found in rodent coprolites collected from the archaeological site Alero Mazquiarán (Chubut Province, 45º44'15"S, 70°25'9"W), which is assigned to the interface of the Araucanian and Tehuelche cultures, dated at 212 ± 35 years B.P. The faecal material from two unidentified rodent species (X-10 and X-11) was collected from one human pelvic cavity found in a multiple burial. The faecal samples were processed and examined using paleoparasitological procedures. The X-10 coprolites were positive for eggs of Monoecocestus sp. (Cestoda: Anoplocephalidae) and the X-11 faeces were positive for Pterygodermatites sp. (Nematoda: Rictulariidae), Trichosomoides sp. (Nematoda: Trichosomoididae) and Monoecocestus sp. In this study, we discuss parasitic life cycles, the zoonotic importance of parasites and the behaviour of the aboriginal people.Key words: paleoparasitology -helminths -rodents -Patagonia -nematodes -anoplocephaliids Parasites are useful as biological markers for the interpretation of the ecology of their hosts; they also play important roles in regulating the populations and communities of the hosts that they infect (Williams et al. 1992, Poulin 2007. In addition, parasites can be used as tags to determine the history of their hosts (Manter 1967, Brooks 1979, Morand et al. 2006. Helminth eggs, found in faeces and in sediments or other materials, vary widely in their ability to resist desiccation and destruction. Eggs are one of the most resilient stages in the life cycle of parasitic worms. Therefore, inferences can be made regarding evolutionary time using the recognition of eggs collected from old infected materials, i.e., from coprolites (Pike 1968).In the archaeological site named Alero Mazquiarán (Chubut Province, Argentina), a multiple human burial was discovered. Parasites attributed to rodents, including several eggs of Trichuris sp. (Nematoda), one egg probably of taeniid, and two eggs of Anoplocephalidae (Cestoda) were recovered from sediment in one human pelvic cavity. Along with the sediment, rodent coprolites of two distinct morphological aspects (X-10 and X-11) were discovered. These samples were processed and examined microscopically. The presence of oribatid mites, Moniezia sp., Capillaria sp., Trichuris sp., ascaridid eggs, and differences in the parasite burden of both rodent faeces were available from previously published parasitological data (Fugassa 2006a, b).The aim of this paper was to broaden the current paleoparasitological information using a new set of obser- vations of the preserved coprolites, X-10 and X-11. The purpose of this study was to review the parasite fauna and to examine the existence of potentially zoonotic parasites and the role of rodents in ancient human populations in Patagonia. MATERIALS AND METHODSAlero Mazquiarán is an archaeological site located in the South of Chubut Province, Argentina (45º44'15"S, 70°25'9"W) ( Fig. 1), assigned to the interface of the Araucanian and Tehuelche cultures.

“…The new species belongs to the subgenus Pterygodermatites (Paucipectines) because the oral opening is subterminal, however, the specimens described have 39-41 pairs of prevulvar cuticular processes and differ from the range described (29-39) by Quentin (1969). Other species belonging to this subgenus (P. (P.) kozeki (Chabaud and Bain, 1981), P. (P.) jagerskioldi (Lent and Freitas, 1935), P. (P.) dipodomis (Tiner, 1948), P. (P.) baiomydis Lynggaard et al, 2014) possess more than 39 prevulvar cuticular processes. These variations reported for the subgenus Paucipectines suggest the need to amend the diagnosis of this subgenus.…”

“…These variations reported for the subgenus Paucipectines suggest the need to amend the diagnosis of this subgenus. To date, 11 species of this subgenus have been described in the Neotropics (Travassos, 1928, Lent andFreitas, 1935;Quentin, 1967;Sutton, 1979Sutton, , 1984Navone and Lombardero, 1980;Chabaud and Bain, 1981;Navone, 1987;1989;Navone and Suriano, 1992;Lopes Torres et al, 2007;Jiménez and Patterson, 2012;Lynggaard et al, 2014;Cardia et al, 2015); the new species differs from P. (P.) elegans (Travassos, 1928), P. (P.) zygodontomis (Quentin, 1967), P. (P.) azarai Sutton, 1984, P. (P.) spinicaudatis Navone and Suriano, 1992, P. (P.) hymanae Jiménez and Patterson, 2012, and P. (P.) baiomydis Lynggaard et al, 2014, in showing spicules nearly equal in size (vs. unequal in size in the aforementioned species) and only 1 cuticular semicircular fan on the ventral surface of the male posterior end, whereas in the other species, the number of fans varies from 3 to 4, excepting P. elegans, which lacks fans.…”

“…In the Neotropical region, there are 11 species included in Pterygodermatites (Paucipectines), 4 of them parasitize cricetid rodents (Quentin, 1967;Sutton, 1979Sutton, , 1984Lynggaard et al, 2014), 2 in bats (Travassos, 1928;Cardia et al, 2015), 4 in marsupials (Lent and Freitas, 1935;Chabaud and Bain, 1981;Navone, 1989;Navone and Suriano, 1992;Lopes Torres et al, 2007;Jiménez and Patterson, 2012) and only 1 in xenarthrans, Pterygodermatites (Paucipectines) chaetophracti (Navone and Lombardero, 1980).

Pterygodermatites is a cosmopolitan genus of nematodes from mammals, and it is frequently encountered in the parasite fauna of armadillos (Mammalia, Xenarthra, Cingulata). In this work, a new species, Pterygodermatites ( Paucipectines) argentinensis, is described, and new morphometric data, new host records, and the geographical distribution of Pterygodermatites ( Paucipectines) chaetophracti are provided. We examined 109 hosts belonging to Chaetophractus vellerosus, Chaetophractus villosus, Cabassous chacoensis, Dasypus hybridus, Tolypeutes matacus, and Zaedyus pichiy, from several regions of Argentina. Pterygodermatites ( Paucipectines) argentinensis can be distinguished from P. ( P.) chaetophracti by the morphology and size of esophageal teeth of both sexes, by subequal and longer spicules, by having only 1 precloacal cuticular semicircular fan in males, and by a greater number of cuticular processes in females. Cabassous chacoensis and Zaedyus pichiy are new hosts for Pterygodermatites ( P.) chaetophracti.
