Six species of 3 genera belonging to the fur mite family Listrophoridae were recorded on skins of South American rodents of the cricetid subfamily Sigmodontinae housed in the Bavarian State Collection of Zoology (Munich, Germany). Among them, Amlistrophorus geoxus sp. nov. from Geoxus valdivianus from Chile is described as a new for science, and males of Prolistrophorus amazonicus amazonicus Fain, 1971 are recorded for the first time. The full generic status for the subgenus Amlistrophorus of the genus Prolistrophorus proposed by Fain et al. (1996) is not supported, and Prolistrophorus musculinus Fain, 1973 stat. nov. (formerly a subspecies of P. amazonicus) from Mus musculus (Rodentia: Muridae) from Suriname is raised to species status. New hosts are recorded for the following species: Prolistrophorus argentinus (Hirst, 1921) from Holochilus brasiliensis and H. chacarius from Argentina, P. amazonicus from Calomys callosus from Argentina and Bolivia, C. laucha and C. musculinus from Argentina, P. akodon Fain and Lukoschus, 1982 from Akodon montensis from Argentina, P. nectomys Fain, 1971 from Nectomys palmipes from Peru and Melanomys caliginosus from Panama, and Sclerolistrophorus oxymycteris Fain, 1976 from Oryzomys laticeps from Brazil.

We investigated the relation between the footprint shape of the fore and hind feet of sigmodontine rodents and their levels of arboreal activity. Footprint shape was obtained by analyzing the impressions left by identified animals captured in the field after being forced to pass through ink-tracking tunnels or by pressing their previously inked feet on a paper sheet. We used geometric morphometric techniques that use superimposition of landmarks (centers of the pads) to obtain footprint shape variables, which were reduced using multivariate analysis (principal component analysis). Arboreal activity was inferred on the basis of the proportions of individuals captured in arboreal traps (1.5–2.5 m height). Regression analysis of body size and the variable that best represented the footprint shapes (first principal component—PC1) did not indicate significant allometric effects on such shapes. We did not detect any significant phylogenetic effects on the arboreal activity of the rodents, either. The results indicated that the PC1 concerning footprint shapes of ten sigmodontine rodents efficiently reflects the degree of use of arboreal strata by these animals. The species studied showed different levels of arboreal activity and their hind footprints (r 2 = 0.94) were better indicators of arboreality than the fore footprints (r 2 = 0.53). These findings suggest a likely trade off for the fore feet functions. Such functions are probably not strictly related to locomotion. Other biomechanical functions (e.g., shock absorption) and/or manipulation (e.g., food manipulation and grooming) may exert relatively greater influence on the shape of fore feet.

The aim of this study was to assess the phylogenetic position of the South American cricetid genus Neotomys using two molecular markers: one nuclear (Irbp) and one mitochondrial (mt-cyb). This genus is currently considered as incertae sedis in the Sigmodontinae radiation. The phylogenetic relationships were estimated using three approaches: Bayesian inference, maximum likelihood and parsimony. We found the genus Neotomys closely related to the genera Euneomys and Irenomys, which are also considered incertae sedis. Our results suggest a common origin for this group of genera; this fact should be reflected in the taxonomy as a supra generic group with a tribal level. However, further and deeper analysis of both molecular and morphological data are needed to diagnose and formalize the proposed tribe. The relationships of this clade to the other members of Sigmodontinae were not clear as assessed by these data sets. The three genera are distributed around the Central and Southern Andes in South America evidencing that the Andes have played an important role in the diversification of several tribes of sigmodontine rodents.

Hymenolepidid cestodes in Myodes glareolus from Lithuania and additional specimens originally attributed to Arostrilepis horrida from the Republic of Belarus are now referred to A. tenuicirrosa. Our study includes the first records of A. tenuicirrosa from the European (western) region of the Palearctic, and contributes to the recognition of A. horrida (sensu lato) as a complex of cryptic species distributed broadly across the Holarctic. Specimens of A. tenuicirrosa from Lithuania were compared to cestodes representing apparently disjunct populations in the eastern Palearctic based on structural characters of adult parasites and molecular sequence data from nuclear (ITS2) and mitochondrial (cytochrome b) genes. Morphological and molecular data revealed low levels of divergence between eastern and western populations. Phylogeographic relationships among populations and host biogeographic history suggests that limited intraspecific diversity within A. tenuicirrosa may reflect a Late Pleistocene transcontinental range expansion from an East Asian point of origin.

We employed a live-trapping grid encompassing several discrete vegetation patches to analyze spatial differences in the demographic structure of an Oxymycterus rufus (Fischer, 1814) population living on the delta of the Parana River, Argentina. Abun­dance, residence and reproduction of both females and males have been associated with microhabitats where food (measured through the availability of arthropods) was more abundant, and were not associated with the plant cover of those microhabitats. Our results emphasize the importance of food availability in the spatial distribution of resident and reproductive individuals, and hence in the survival and breeding success of their populations in the Parana delta area.

Cytogenetic analyses were performed in 39 specimens of Delomys trapped in six localities distributed along the Atlantic forest range of the genus. Only two karyotypic forms were found: 2n = 72, FN = 90 to the north and 2n = 82, FN = 80 to the south, with an overlapping area in São Paulo and Paraná states. No hybrids were found and given the large difference in karyotype it is likely that any hybrids produced would be infertile. Based on the skin coloration and type localities of the species described it is suggested that the 2n = 72 taxon corresponds to Delomys sublineatus and the 2n = 82 form to D. dorsalis.

An examination of 16 bank voles from Poland (Pomerania) revealed the presence of two species of the family Demodecidae (Acari, Prostigmata), specific to the host. Demodex buccalis Bukva, Vitovec et Vlcek, 1985 was noted only in one bank vole, where 18 specimens were found: the prevalence of infestation being 6.3%. D. glareoli Hirst, 1919 was observed in 75% of the examined bank voles, in which were on average 5.1 specimens. Additionally, mites of the both species exhibited topical specificity – representatives of D. buccalis were found in the tissues of the tongue and oral cavity of the host, while D. glareoli, being a species associated with hair follicles, was noted in skin specimens from different body areas, particularly the head area. Infestations with demodecids were not accompanied by disease symptoms. D. buccalis and D. glareoli are a new species for the fauna of Poland.

Sixteen African giant rats (Cricetomys gambianus Waterhouse), consisting of 8 male and 8 female rats, were used to determine neurocranial measurements of the skulls. The mean neurocranial volume was 5.06 ± 0.05 mL, neurocranial length was 3.33 ± 0.08 cm, and the neurocranial height and index were 1.39 ± 0.04 cm and 41.74%, respectively. The mean whole skull length and height were 6.32 ± 0.06 cm and 2.98 ± 0.05 cm, respectively. The skull without the mandible was 1.83 ± 0.02 cm in height, and the skull index was 28.41 ± 0.58. The height of the skull of the African giant was approximately half (47%) of the skull length. The mean height and width of the foramen magnum were 0.78 ± 0.01 cm and 0.96 ± 0.02 cm, respectively, while the foramen index was below 100 at 81.46 ± 1.42. Parameters for the whole skull height and foramen magnum width showed significant difference between both sexes at p < 0.05. The foramen magnum showed shape variations and there were multiple hypoglossal foramina in over 87% of the rats. This study, in conclusion, highlighted the possibility of the estimation of the brain density and the use of the African giant rat for cranial pressure experiments.

Six fur-mite species of the genus Prolistrophorus Fain, 1970 (Acariformes: Listrophoridae) were recorded from Central and South American rodents of the subfamily Sigmodontinae (Rodentia: Cricetidae). Among them, Prolistrophorus (Aprolistrophorus) parabidentatus sp. nov. from Akodon azarae from Argentina and Prolistrophorus (Aprolistrophorus) tylomys sp. nov. from Tylomys nudicaudus from Guatemala are described as new for science. New hosts are recorded for the following species: Prolistrophorus (Prolistrophorus) grassii (Radford, 1954) from Zygodontomys brevicauda from Colombia, P. (P.) frontalis (Hirst, 1921) from Oligoryzomys sp. from Argentina, P. (P.) argentinus (Hirst, 1921) from Melanomys caliginosus, Akodon affinis from Colombia and Scapteromys aquaticus from Argentina, Prolistrophorus (Beprolistrophorus) hirstianus Fain, 1973 from Scapteromys aquaticus from Argentina.

Heligmosomoides vandegrifti sp. nov. (Nematoda, Heligmosomidae) is described from Peromyscus maniculatus (Rodentia, Cricetidae) from Pennsylvania, USA. It differs from its closest congener, H. douglasi, in the number of cuticular ridges (35 vs. 32 in male, 36 vs. 41 in female at mid-body), longer bursal rays 2 in relation to rays 3, and in having smaller spicules (635–740 μm long vs. 1 mm). It is proposed that both H. douglasi and H. vandegrifti sp. nov. are parasites of capture from species in North American arvicoline rodents.
