Serra da Capivara National Park (SCNP) in Northeast Brazil has the largest concentration of prehistoric sites in the Americas where studies of coprolites of ancestral parasitic fauna reported the presence of morphotypes of nematode eggs identified as Aspidoderidae and Trichostrongyloidea from dasypodid hosts. Among the current mammals inhabiting the park, the opossum Didelphis albiventris and the armadillo Dasypus novemcinctus were found roadkill in the nearby area. The aim of this work was to perform an integrative taxonomic analysis of adult nematode parasites of D. albiventris (N = 3) and D. novemcinctus (N = 2) found roadkill in the SCNP using morphological, ultrastructural and genetic approaches. The nematodes studied included Aspidodera raillieti and Aspidodera subulata (Aspidoderidae) collected from D. albiventris, and Aspidodera binansata, Aspidodera vazi (Aspidoderidae) and Hadrostrongylus speciosum (Trichostrongylidae) from D. novemcinctus. A new geographic locality of four species of Aspidoderidae and one Trichostrongylidae species are reported with new ultrastructural data using scanning electron microscopy of A. binansata and A. vazi. New genetic data of aspidoderids include sequences of partial 18S rRNA (SSU) and partial 28S rRNA (LSU) genes of A. raillieti, the first sequence of 16S rRNA of A. vazi and additional sequences of mitochondrial DNA cytochrome c-oxidase subunit 1, internal transcribed spacer 1, 2 and 5.8S rRNA gene of A. raillieti. These are the first partial sequences of 18S rRNA (SSU) and 28S rRNA (LSU) genes of species of the family Aspidoderidae, linked to a vouchered specimen.

“…Species of Syphacia generally exhibit a co-evolutionary relationship with their hosts, with each Syphacia species showing specificity with the host genus (Hugot, 1988;Robles, 2010). Eggs of Syphacia were found in K. rupestris coprolites from Brazil, dated at 5300 BP (Vieira de Souza et al, 2012). Future studies on rodent coprolites can contribute to the knowledge of the evolutionary patterns of Syphacia with their hosts.…”

The present study aimed to identify endoparasites from faecal samples of Kerodon rupestris, an endemic rodent of the Brazilian semiarid region. Samples collected from 10 locations at the Parque Nacional Serra da Capivara, Piauí State, Brazil were analyzed. Each faecal samples was processed, rehydrated, homogenized, and processed by spontaneous sedimentation. Morphological and morphometric characteristics of gastrointestinal parasites were observed using light microscopy. A total of three taxa from helminth and protozoan parasites were found. The results demonstrated parasite remains in 6/10 localities, and a high occurrence of Trichuris cf. gracilis, in 5/10 localities. Egg morphometric data was compared with Trichuris spp. egg Brazilian rodents. Two new parasite records were identified in K. rupestris, a nematode, Helminthoxys sp. (Oxyuridae) and a possible coccidian. The findings are discussed with taxonomic and ecological literature of intestinal parasites from rodents. The role of K. rupestris as source of ecological information in the region is suggested.
