Abstract
The genetic diversity of Syphacia nematodes (intestinal parasites of rodents) was studied in the hybrid zone of two sister species of common voles, Microtus arvalis and Microtus obscurus, in the Oka River valley, east of Moscow. Syphacia nematodes of other rodent species (Microtus rossiaemeridionalis, Alexandromys oeconomus, Sylvaemus uralensis, and Apodemus agrarius) that inhabit the area were also studied. Phylogenetic trees for the studied nematodes were inferred from the analysis of nuclear ITS1+5.8S+ITS2, LSU rDNA, and mitochondrial CO1 gene partial sequences. Syphacia nematodes of the studied area form three well-defined clades in the phylogenetic tree of this genus. Morphological analysis revealed similarities between the obtained sequences with those of known Syphacia species from the GenBank database, which enabled identifying these three clades up to the species level: S. montana, S. agraria, and S. frederici. Russian haplotypes of Syphacia are different from West European and East Asian haplotypes with pronounced genetic distances. A high level of specificity was reported for two of these three species (S. frederici, only in Sylvaemus uralensis; S. agraria, only in Apodemus agrarius). S. montana was found in different species of voles. Remarkably, S. montana specimens from M. arvalis and M. obscurus were genetically uniform, while S. montana, specimens from hybrids between these two species formed a separate clade distant from those originating from non-hybridised hosts.

Abstract
Wellcomia species (Oxyuridae, Syphaciinae) parasitise several families of rodents from Africa, Asia and America with diverse ecological characteristics. A new species of Wellcomia is described based on specimens obtained from the plains viscacha Lagostomus maximus (Chinchillidae) from Argentina. The description includes morphometric and ecological aspects and an emended diagnosis of the genus Wellcomia. In addition, a molecular characterisation (18S rRNA) and an exploratory analysis of the genetic distances of the species included in this genus are provided. The new species, Wellcomia hugoti n. sp., differs from other species of the genus in the morphology of the cephalic plate, the ventral rugose area in males and the vulva in females. The new species showed a low prevalence (7.7%) and a high mean abundance (73.8). The genetic distances detected do not allow a comprehensive assessment of the monophyly of the genus. This is the seventh record of this genus in rodents from the Americas, the second in rodents from Argentina and the first record for the family Chinchillidae.

Abstract
The first integrative approach using sequences of two genes (18S and 28S rRNA) plus morphological and life history traits, was explored in Pharyngodonidae nematodes parasitic in reptiles. Additionally, first genetic characterization of Parapharyngodon bainae and new data on its morphology are given. This approach evaluated the phylogenetic relationships among genera within Pharyngodonidae, as well as the importance of their diagnostic morphological features. Specimens of P. bainae were collected from faecal pellets of the lizard Tropidurus torquatus in the State of Minas Gerais, Brazil. Nematodes were fixed for scanning electron microscopy and molecular procedures. Morphological observations revealed the accurate structures of cephalic end, of cloacal region in males, of vulva and eggs. Phylogenetic reconstructions were based upon four datasets: aligned sequences of the 18S, of the 28S, of both concatenated genes and of combined morphological and molecular datasets. Bayesian inference and maximum likelihood were performed to infer the phylogenies of molecular datasets and maximum parsimony to infer that of all-combined data. Pharyngodonid parasites of reptiles seem to configure two general monophyletic lineages, as previously assertions. Results also showed the monophyly of Spauligodon, Skrjabinodon and Parapharyngodon, as well as the clear separation between the latter and Thelandros. Combination of datasets improved nodal supports. Analysis of the all-combined datasets revealed the importance of vulval position and egg morphology as phylogenetic informative traits. However, characters of male caudal morphology appear as are highly homoplastic, and seem to be product of convergent evolution or multiple losses of ancestral traits. The closely-related Thelandros and Parapharyngodon are kept valid and their diagnosis should be based upon the position of the operculum in eggs (terminal or subterminal, respectively). Some inconsistencies in the scarce molecular and morphological databases were noted. Thus, new genetic data is required for further conclusions and current database must be evaluated with attention.

Abstract
Spauligodon papuensis sp. nov. from the large intestines of Cyrtodactylus epiroticus (Gekkonidae) from Papua New Guinea is described and illustrated. Spauligodon papuensis sp. nov. represents the 54th species assigned to the genus and the second species from the Oceanic Region. The new species is separated from congeners by the unique combination of aspinose filamentous tail and no spicule in the male; and spinose filamentous tail, fusiform, flanged eggs, and postbulbar vulva in the female. Four additional species of nematodes were also found in C. epiroticus: mature specimens of Cosmocerca zugi, Falcaustra papuensis, Physalopteroides milnensis and larvae of Abbreviata sp.

Abstract
We evaluated PCR testing of filter tops from cages maintained on an IVC system through which exhaust air is filtered at the cage level as a method for detecting parasite-infected and -infested cages. Cages containing 4 naïve Swiss Webster mice received 360 mL of uncontaminated aspen chip or α-cellulose bedding (n = 18 cages each) and 60 mL of the same type of bedding weekly from each of the following 4 groups of cages housing mice infected or infested with Syphacia obvelata (SO), Aspiculuris tetraptera (AT), Myocoptes musculinus (MC), or Myobia musculi (MB) and Radfordia affinis (RA; 240 mL bedding total). Detection rates were compared at 30, 60, and 90 d after initiating bedding exposure, by using PCR analysis of filter tops (media extract and swabs) and testing of mouse samples (fur swab [direct] PCR testing, fecal flotation, anal tape test, direct examination of intestinal contents, and skin scrape). PCR testing of filter media extract detected 100% of all parasites at 30 d (both bedding types) except for AT (α-cellulose bedding, 67% detection rate); identified more cages with fur mites (MB and MC) than direct PCR when cellulose bedding was used; and was better at detecting parasites than all nonmolecular methods evaluated. PCR analysis of filter media extract was superior to swab and direct PCR for all parasites cumulatively for each bedding type. Direct PCR more effectively detected MC and all parasites combined for aspen chip compared with cellulose bedding. PCR analysis of filter media extract for IVC systems in which exhaust air is filtered at the cage level was shown to be a highly effective environmental testing method.

Abstract
The entry of infectious agents in rodent colonies occurs despite robust sentinel monitoring programs, strict quarantine measures, and stringent biosecurity practices. In light of several outbreaks with Aspiculuris tetraptera in our facilities, we investigated the presence of anthelmintic resistance and the use of exhaust air dust (EAD) PCR for early detection of A. tetraptera infection. To determine anthelmintic resistance, C57BL/6, DBA/2, and NCr nude mice were experimentally inoculated with embryonated A. tetraptera ova harvested from enzootically infected mice, followed by treatment with 150 ppm fenbendazole in feed, 150 ppm fenbendazole plus 5 ppm piperazine in feed, or 2.1 mg/mL piperazine in water for 4 or 8 wk. Regardless of the mouse strain or treatment, no A. tetraptera were recovered at necropsy, indicating the lack of resistance in the worms to anthelmintic treatment. In addition, 10 of 12 DBA/2 positive-control mice cleared the A. tetraptera infection without treatment. To evaluate the feasibility of EAD PCR for A. tetraptera, 69 cages of breeder mice enzootically infected with A. tetraptera were housed on a Tecniplast IVC rack as a field study. On day 0, 56% to 58% of the cages on this rack tested positive for A. tetraptera by PCR and fecal centrifugation flotation (FCF). PCR from EAD swabs became positive for A. tetraptera DNA within 1 wk of placing the above cages on the rack. When these mice were treated with 150 ppm fenbendazole in feed, EAD PCR reverted to pinworm-negative after 1 mo of treatment and remained negative for an additional 8 wk. The ability of EAD PCR to detect few A. tetraptera positive mice was investigated by housing only 6 infected mice on another IVC rack as a field study. The EAD PCR from this rack was positive for A. tetraptera DNA within 1 wk of placing the positive mice on it. These findings demonstrate that fenbendazole is still an effective anthelmintic and that EAD PCR is a rapid, noninvasive assay that may be a useful diagnostic tool for antemortem detection of A. tetraptera infection, in conjunction with fecal PCR and FCF.

Abstract
Mus musculus (Rodentia: Muridae) were infected by a nematode belonging to the order Oxyurida. According to external morphological characters it was found to be Aspiculuris tetraptera Schulz, 1924. Present communication deals with molecular characterization of A. tetraptera infecting intestine of Mus musculus in Meerut (U.P.), India. A partial sequence of 18S ribosomal and cytochrome c oxidase subunit 1 (Cox 1) mitochondrial DNA analyses were performed. Sequence corresponding to 18S rRNA and mt Cox 1 gene was identical to sequences reported for A. tetraptera on GenBank. These results confirm the taxonomic validation of A. tetraptera parasitizing Mus musculus. This is the first report of molecular study of A. tetraptera in India.

Abstract
The aim of this paper is to describe Syphacia kinsellai n. sp. (Nematoda: Oxyuridae) from the cecum of Oligoryzomys nigripes (Olfers 1818) (Sigmodontinae: Oryzomyini) captured in Misiones Province, Argentina. The new species can be differentiated from other species of the genus principally by the shape of the cephalic plate; distribution of submedian papillae and amphids; development of porous badge; presence of derids in females; absence of cervical and lateral alae; shape and structure of accessory hook of gubernaculum; and distance of excretory pore and vulva from the anterior extremity. Until the present, only two species of Syphacia had been reported from Argentina in sigmodontine rodents, the first one parasitizes an Oryzomyini host and the second one an Akodontini host. This new species is the second record of Syphacia from the tribe Oryzomyini in Argentina; however, we propose that the first record, S. oryzomae, should be treated as a nomen dubium.

Abstract
Okinawandros goldbergi n. gen., n. sp. and Ataronema sekii n. gen., n. sp. (Nematoda: Pharyngodonidae) are described from rhacophorid frogs of the Ryukyu Archipelago, Japan. Okinawandros n. gen. resembles Batracholandros Freitas et Ibañez, 1965 and Synodontisia Petter, Vassiliades et Troncy, 1972 but is readily distinguished from the former in lacking laterally situated genital papillae and by having anteriorly directed vagina and from the latter by having operculated eggs and lacking a spicule. Ataronema n. gen. most closely resembles Parathelandros Baylis, 1930 but is readily distinguished because the posterior pair of caudal papillae is not rosette shaped and the eggs are not operculated. Morphological notes of Pharyngodon polypedatis Yamaguti, 1941 are included.

Abstract
During the investigation of insect nematodes of North-East India, a new species of Binema (Travassosinematidae: Thelastomatoidea) was recovered from the intestine of Gryllotalpa africana Beauv. It is described and illustrated as Binema anulinervus n.sp. Three known species namely B. ornata Travassos, 1925, B. mirzaia (Basir, 1942) Basir, 1956 and B. korsakowi (Sergiev, 1923) Basir, 1956 have also been collected, redescribed and illustrated in the present study. The new species differs from all known species and only comes close to B. pseudornatum Leibersperger, 1960 for having caudal flagellate appendage. Key to species of the genus and a comparative measurement chart are given in Table 1.

Abstract
Four species of the genus Mehdiella Seurat, 1918 are redescribed: M. cristata Petter, 1966 and M. stylosa dollfusi Petter, 1966, parasite of Pyxix arachnoides Bell, 1827 from Madagascar, M. s. stylosa (Thapar, 1925) and M. uncinata (Drasche, 1884), parasite of Testudo graeca Linneaus, 1758, Testudo hermanni Gmelin, 1789 and Testudo horsfieldii (Gray, 1844) from Palaearctic region. Light microscopy and scanning electron microscopy (SEM) studies revealed new informations on the morphology of these species. On the basis of this morphological study, the sub-species Mehdiella stylosa dollfusi and M. s. stylosa are raised to level of species. The position of Mehdiella cristata among the species of the genus Mehdiella and the relationships among the species of the genus Mehdiella are discussed. A key to the eight valid species Mehdiella is given.

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
As part of a study on the helminth parasites of South African lizards several species of saurians were collected from localities in the North West Province, the Northern Province, Mpumalanga Province and Gauteng Province. Spauligodon blydeensis (Hering-Hagenbeck, 2001) from the Cape thick-toed gecko, Pachydactylus capensis, Spauligodon molpoensis (Hering-Hagenbeck, 2001) from Wahlberg's velvet gecko, Homopholis wahibergii, Parapharyngodon margaritiferi, Hering-Hagenbeck, 2001 from the skink, Mabuya margaritifer, Parapharyngodon gerrhosauri, Hering-Hagenbeck, 2001 from the plated lizard, Gerrhosaurus flavigularis and Skrjabinodon mabuyae (Sandground, 1936) Inglis, 1968 from the skinks Mabuya punctatissima, Mabuya spilogaster and Mabuya varia are redescribed. The different Spauligodon spp. in the subcontnent may be separated on the presence or absence of spicules in the males, the presence or absence of spines on the tail of both the males and females, as well as on the size and shape of the eggs, and the configuration of the polar caps. The Parapharyngodon spp. are distinguished mainly by the morphological characters of the males, such as the width of the caudal alae and the size of the pre- and adanal papillae. Female Parapharyngodon spp. closely resemble each other and some could not be identified to the species level since males were absent. Spinose larvae, together with adult Parapharyngodon spp. were recovered from Mabuya margaritifer. All Parapharyngodon spp. larvae described to date are spinose and since the larvae in this study were collected together with adult Parapharyngodon spp., we consider them to belong to the same genus. Skrjabinodon mabuyae differs from the closely related Skrjabinodon mabuiensis in the presence of a spicule in the male and lateral alae in the female. The former nematode is described for the first time from skinks in South Africa.

Abstract
Thelandros schusteri Hering-Hagenbeck, 2001, Thelandros luciusi Hering-Hagenbeck, 2001, Thelandros boomkeri Hering-Hagenbeck, 2001, Tachygonetria bainae Hering-Hagenbeck, 2001, Tachygonetria chabaudi Hering-Hagenbeck, 2001 and Tachygonetria petterae Hering-Hagenbeck, 2001 from the plated lizard, Gerrhosaurus validus validus A. Smith 1849 from three localities in the north-eastern region of South Africa are redescribed. Classification keys are available only for the males of the species and because male and female nematodes in copula were not observed in this study as well as the similarity of the females, it was not possible to identify the females to the species level. Thelandros schusteri, Thelandros boomkeri and Thelandros luciusi were provisionally paired with female Type E, Tachygonetria bainae with female Type C, Tachygonetria chabaudi with female Type A and Tachygonetria petterae with female Type D. Female Types B and F could not be paired. The richness and composition of species of the Pharyngodonidae of Gerrhosaurus validus validus is close to that of tortoises and differs from the pharyngodonid fauna of the insectivorous lizards that have been studied. In the latter, only the genera Spauligodon, Skrjabinodon and Parapharyngodon were recovered. The pharyngodonid fauna of Gerrhosaurus validus validus seems to have originated by capture from local herbivorous reptiles. The three Tachygonetria spp. most closely resemble forms in South African tortoises. The three Thelandros spp. redescribed here not only show strong similarities to those of herbivorous Agama spp., but also to those parasitic in tortoises and could have been acquired from either.

Abstract
Pharyngodonid nematodes (Oxyuroidea) belonging to the genus Alaeuris Thapar, 1925, were collected from the posterior gut of Gallotia stehlini (Lacertidae) from Grand Canary Island. Two species Alaeuris stehlini n. sp. and Alaeuris numidica canariensis n. ssp. were identified. The new species is described in which the long thin males are characterized by narrow caudal alae, a rounded first pair of adanal papillae non pedunculate, the second pair attached and elongate, the three pair teated; a short narrow V plate and a relatively long caudal appendage. The females are also long and thin with a slightly salient vulva, a conical pointed caudal appendage, oesophageal length approximately one third of body, excretory pore below the oesophageal bulb. The new subspecies most closely resembles Alaeuris numidica numidica. (Seurat, 1918) Petter, 1966 and Alaeuris numidica madagascariensis Petter, 1966.

Abstract
Random amplified DNA markers (RAPD; Williams et al., 1990) were used to obtained specific RAPD fragments characterising different species of oxyuroids. We tested six species of worms parasitizing vertebrates or invertebrates: Passalurus ambiguus Rudolphi, 1819, parasite of Leporids; Syphacia obvelata (Rudolphi, 1802) Seurat, 1916, a parasite of rodents; Blatticola blattae (Graeffe, 1860) Chitwood, 1932 parasite of the cockroach Blattella germanica; Hammerschmidtiella diesingi (Hammerschmidt, 1838) Chitwood, 1932 and Thelastoma bulhoesi (Magalhaes, 1990) Travassos, 1929, parasites of the cockroach Periplaneta americana, and an undescribed parasite species of a passalid insect from New Caledonia. Among 15 oligonucleotides tested, nine produced several specific bands allowing the interspecific discrimination.

Abstract
Two different methods are successively used for the systematic study of the Syphaciinae, a parasitic group of pin-worms specific for the Rodents and Lagomorpha. The statistical method permits to build a "phenetic classification"; the cladistic method permits to build a "phylogenetic classification". The classification finally proposed is principally found on the results of the morphological study of the parasites, but has also in view the integration of all available data concerning the biology, the biogeography and the phylogeny of the hosts.

Abstract
A review of the Oxyurids parasites of Primates shows that most of the species described in the Malagasy Lemurs and in the Old World Monkeys are not single species, but couples of sister-species. The sister-species of each couple may be differentiated sometimes only by the characteristics of male spicule (less evoluated species), sometimes by other characteristics (cephalic structures, length of oesophagus, etc., in more evoluated species). In the first instance only males can be identified, in the second instance females may also be identified. In the Human parasites, which are very closely related to those of the Old World Monkeys, two types of spicules were described and we consider that each type belongs to a different species: Enterobius vermicularis (L., 1758) for the larger spicule (100 to 122 micrometers), and Enterobius gregorii n. sp. for the shorter spicule (70 to 80 micrometers).

Abstract
Description of Kahmannia eliomydis n. gen., n. sp., an Heretoxynematid Nematode parasitizing the intestine of the Garden dormouse Eliomys quercinus (Linnaeus, 1766) (Rodentia: Gliridae) in the island of Minorca (Balearies). Kahmannia n. gen. is proposed to include in the Heteroxynematinae the intestinal parasites from Rodents characterized by: oral opening circular without lips; buccal capsule triangular with small oesophageal teeth; oesophagus elongated with spherical bulb with strongly developed valves, clearly individualized and separated by a well-defined oesophageal isthmus; cephalic vesicle present, with sinuous peribuccal ornamentation forming slender crown with eight digitations; cuticular striations marked; lateral and cervical alae absent; male without caudal lateral alae, without precloacal cuticular ornamentation on ventral surface and without gubernaculum, but with single spicule; and thin-shelled eggs without operculum. It is the first Nematode Oxyuroidea known parasitizing Rodents Glirimorpha.
