    Abstract Context Striped skunks (Mephitis mephitis) occur across a wide range of habitats in North America and co-occur with many wildlife that use similar denning structures. Few studies have quantified interspecific activity at striped skunk dens despite the concomitant implications for pathogen transmission due to direct and indirect contact at shared dens. Further, no studies have examined differences in striped skunk denning behaviour across an urban–rural gradient with various forms and degrees of human modification. Aims Our study described striped skunk denning behaviour in the lower Midwestern United States and assessed interspecific activity at dens. Methods We used radiotelemetry and camera traps to observe winter denning behaviour of radiocollared striped skunks and other sympatric species across an urban–rural gradient in southern Illinois, USA, during November–February 2018–2021. We examined correlations between striped skunks and other species captured in photos at dens. We tested for an effect of human modification on the number of dens used by striped skunks, and the effects of weather and landscape variables on striped skunk denning duration. Key results Striped skunks used 3–21 unique dens during a single winter and denned consecutively in one location for 2–59days. All individuals were observed denning for ≥8 consecutive days. Three striped skunks participated in communal denning, and ≤3 striped skunks were observed at a den concurrently. Eleven mammalian species were observed at striped skunk dens, and other species were present in 35.3% of photos. Striped skunk presence at a den was positively associated with Virginia opossum (Didelphis virginiana) presence. Human modification had no significant effect on the number of dens used by a striped skunk. Human modification, distance to stream/shoreline, and mean daily temperature had significant negative effects on striped skunk denning duration. Conclusions We demonstrated that winter denning behaviour of striped skunks in southern Illinois, USA, fits into a latitudinal gradient of behaviour across North America, and dens are a shared resource where direct and indirect intraspecific and interspecific interactions occur. Implications Weather and landscape features influenced winter denning behaviour of striped skunks and ultimately pathogen transmission potential at dens, trends that could potentially be seen in other urban-adapted species.

    Abstract A new species of Heligmosomoides Hall, 1916 is proposed for nematodes collected from deer mice, Peromyscus maniculatus, in western Canada. The unequivocal diagnostic character for this species is the presence of two internal bursal membranes. Only four species, Heligmosomoides bullosus, Heligmosomoides douglasi, Heligmosomoides montanus and Heligmosomoides vandegrifti, are characterized as possessing a single internal bursal membrane. The genetic distance between Heligmosomoides bibullosus sp. nov., and its putative sister clade Heligmosomoides vandegrifti is congruent with their geographic separation by the mountain range of the Rockies and 4000 km; both morphological difference as well as geography and genetic distance suggest isolation among the two species. Further, H. bibullosus sp. nov. infects deer mice (P. maniculatus) whereas H. vandegrifti is frequently collected in white-footed mice (P. leucopus). Finally, this study supports the taxonomic importance of the monodelphic/didelphic condition as a diagnostic trait within the family, the paraphyly of Heligmosomoides, and reveals undocumented diversity of Heligmosomoides in Nearctic rodents of the Neotominae. The present taxon is the third species in members of this subfamily of rodents. http://www.zoobank.org/urn:lsid:zoobank.org:pub:DE78368D-2CDE-4F9D-AB85-A3CE20D957F4

    Abstract During a long-term survey of the parasites of mammals from all over Bolivia, 44 individuals of Oxymycterus inca and 6 of Oxymycterus paramensis were collected and examined for parasites from the foothills and Eastern Cordillera (Los Yungas) of the Andes of Bolivia. Three species of nematode were found including, from the cecum, a previously unknown genus and species of pinworm, Caroloxyuris boliviensis n. gen, n. sp., aspidoderids representing Nematomystes rodentophilus, and from the stomach, Protospirura numidica criceticola. These helminths occurred in prevalences of 25, 9, and 14%, respectively, in O. paramensis. Caroloxyuris boliviensis resembles species included in the genus Syphacia in the structure of the cephalic mask and copulatory organs, and the extension of lateral alae. However, males of this species possess only 2 mamelons on the ventral surface of the body. Caroloxyuris can be recognized as being distinct from both Helminthoxys and Rauschtineria in the ornamentation of the mamelons and the shape of cephalic mask. A redescription of N. rodentophilus is provided, and Nematomystes scapteromi is transferred from Ansiruptodera to Nematomystes.

    Abstract One nine-banded armadillo (Dasypus novemcinctus) and 1 yellow armadillo (Euphractus sexcinctus) were necropsied in the field during an expedition to collect parasites of mammals in Bolivia. A total of 205 Aspidodera binansata Railliet and Henry, 1913 (Heterakoidea: Aspidoderidae), and 40 specimens of Lauroia bolivari n. sp. (Heterakoidea: Aspidoderidae) were recovered from the cecum and large intestines of D. novemcinctus and E. sexcinctus. Aspidodera esperanzae Fujita et al., 1995, is proposed as a junior synonym of A. binansata based on the structure of the cordons on the hood. Lauroia bolivari n. sp. has an undercut cephalic cap and unequal spicules. It differs from other species in the genus in the shape of the cephalic cap and from Lauroia travassosi Proença, 1938, in the relative proportion of the spicules. This is the first record of a member of Lauroia Proença, 1938, for Bolivia.

    Abstract Aspidodera sogandaresi n. sp. (Heterakoidea: Aspidoderidae) from Dasypus novemcinctus Linnaeus, 1758 is herein described. This nematode occurs in armadillos from as far south as the canal zone of Panama, north through central Mexico, and into the southern United States. Previously identified as Aspidodera fasciata (Schneider, 1866), this new species has blunt projections on the lips and lateral expansions at the distal tips of the spicules, whereas A. fasciata has conspicuous digitiform projections on the lips, and a terminal round expansion at the tips of the spicules. Other species of the family present in North America include Aspidodera binansata Railliet and Henry, 1913; Aspidodera vazi Proença, 1937; and Lauroia trinidadensis Cameron, 1939.

    Abstract During our work on biodiversity of parasites of mammals of the Neotropics we collected numerous nematodes assignable to species of the family Aspidoderidae (Nemata: Heterakoidea). These nematodes occur as parasites of the cecum and large intestine of marsupials, rodents and xenarthrans (armadillos) only in the New World. As aspidoderid nematodes have been little studied beyond their alpha taxonomy, it is the purpose of the present paper to apply phylogenetic systematic methods to more completely understand the evolutionary relationships of the included species. Members of the aspidoderid subfamily Lauroiinae have had very little work applied to their systematic relationships and no systematic revisions exist that include all recognized species. Diagnostic characters that define species in this subfamily include plate-like cuticular structures on the anterior end. Herein we define a suite of 52 characters derived from studies of specimens using both light and electron microscopy. Our phylogenetic systematic analysis included the eight known species in the Lauroiinae, seven of the Aspidoderinae and four outgroup taxa. The results indicate that the Lauroiinae is paraphyletic, that the cephalic plates on the anterior end are not synapomorphies for the Lauroiinae, and that structures forming the cordon are present in all species of the family. We propose elimination of the subfamily designations in the family Aspidoderidae and we show the utility of using additional characters in the diagnosis of the family and the genera within this family. The resulting hypothesis should serve as the foundation to understand the historical associations of the nematodes with the mammals they infect. © The Willi Hennig Society 2008.

    Abstract A new species of Spauligodon collected from Cnemidophorus mexicanus and C. deppii is described in this study. The species is placed in Spauligodon because the caudal alae start at the level of the precloacal papillae and embed the adcloacal papillae. The new species is most similar to S. goldbergi, but diagnostic traits of the former are the presence of 2 ridges in lateral alae, flaplike expansions in the caudal end of lateral alae, and a smooth tail for males. This species is the eighth recorded in the neotropics.

    Abstract Pelecitus meridionaleporinus n. sp. from the Tehuantepec jackrabbit is described. The new species differs from Pelecitus helicinus (Molin, 1860) in having delicate transverse striations, a salient vulva, and a readily apparent preesophageal ring; P. helicinus has teardrop cells around the vulva, which are lacking in the species presently described. The new species is different from Pelecitus scapiceps (Leidy, 1886) in having the vulva anterior to the esophageal-intestinal junction and wider lateral alae. Pelecitus scapiceps is found in the tarsal bursa of the hind feet of lagomorphs, whereas P. helicinus is found around tendons of legs and feet of birds. Pelecitus meridionaleporinus n. sp. occurs in the subcutaneous tissue at the base of both ears. This is the second species in Pelecitus Railliet and Henry, 1910 that occurs in New World lagomorphs, and the third found infecting mammals.

    Abstract Seventy-two Mexican garter snakes (Thamnophis eques) and 126 black-bellied garter snakes (T. melanogaster) were collected from 4 localities of the Mesa Central of Mexico between July 1996 and February 1998 and examined for helminths. Both species of garter snakes occurred sympatrically in every locality except in Lake Cuitzeo. Both species of snakes shared 9 helminth species, and in general, T. melanogaster hosted a larger number of species than T. eques. In each locality, a different helminth species showed the highest levels of prevalence and abundance (Spiroxys susanae in Ciénaga de Lerma, Telorchis corti in Lago de Pátzcuaro, Proteocephalus variabilis in Lago de Cuitzeo, and Contracaecum sp. in Lago de Chapala). Helminth communities in garter snakes of the Mesa Central are depauperate and dominated by a single parasite species. In those localities where the snakes occurred in sympatry, helminth communities were, in general, more diverse and species-rich in T. melanogaster. Differences in the ecology and physiology of these species of garter snakes may explain this pattern because black-bellied garter snakes (T. melanogaster) are more aquatic than Mexican garter snakes (T. eques) and primarily eat aquatic prey, potentially exposing themselves to a larger number of helminths transmitted by predator-prey infection. The helminth infracommunities of garter snakes in the Mesa Central of Mexico show a strong Nearctic influence because most of the species infecting these hosts have been recorded in other Nearctic colubrid snakes. However, the helminth infracommunities of these garter snakes are less species-rich and less diverse than those in colubrid snakes in more temperate latitudes. The widespread ecological perturbation of sampling sites in the Mesa Central because of human activity, and geographic differences in foraging ecology of the hosts and, thus, exposure to parasites transmitted by intermediate hosts may help to explain these patterns.
