During a global survey of the diversity of vertebrates and their parasites including the Gobi and desert/steppe biomes ranging from south central to western Mongolia, we found metacestodes (larvae) of Echinococcus multilocularis (Leuckart 1863) in the liver of an individual vole (Microtus limnophilus Büchner 1889) collected in grassland habitat at Har Us Lake, southeast of Hovd, Mongolia. Positive identification of E. multilocularis from near Hovd was made via comparative cyst morphology, study of hooks from the rostellum derived from protoscolexes, and DNA sequencing of the COX1 mitochondrial gene extracted from tissue of the cysts frozen in the field. This …
Pritchardia Boliviensis N. Gen., N. Sp. (Anoplocephalidae: Linstowinae), A Tapeworm From Opossums (Didelphidae) In The Yungas And Lowlands Of Bolivia And Atlantic Forest Of Paraguay, Scott Lyell Gardner, F. Agustín Jiménez Ruiz, Mariel L. Campbell

Harold W. Manter Laboratory of Parasitology: Faculty Publications
During a biodiversity survey of mammals and their parasites in the Beni, Bolivia in the summer of 2000, several spiny rats, Proechimys simonsi Thomas, 1900, were collected and examined for parasites. Herein we describe Lentiella lamothei n. sp. from one of these hosts. This species is can be distinguished from L. machadoi Rêgo, 1964 by having a greater total length but smaller maximum width, a greater number of segments, a smaller cirrus sac, a smaller scolex diameter, and in the eggs, a larger pyriform apparatus. In addition, we formally validate the genus Lentiella Rêgo, 1964, that had been placed in …

Redescription Of Cryptocotyle Thapari Mcintosh, 1953 (Trematoda: Heterophyidae), In The River Otter Lutra Longicaudis From Bolivia, Scott Lyell Gardner, Peter T. Thew
Harold W. Manter Laboratory of Parasitology: Faculty Publications
Cryptocotyle thapari McIntosh, 1953 (Digenea: Heterophyidae), collected originally from a South American otter that died at the U.S. National Zoo in Washington, D.C., is redescribed from specimens obtained from a river otter, Lutra longicaudis, collected from the Rı´o Matos in the Departamento de Beni, Bolivia. These individuals of C. thapari are slightly smaller than the type specimens, but they have similar features, including testes arranged in tandem and a well-defined ventrogenital sac. We redescribe this species because the original description was based on only 3 individuals, and the figures lacked detail. This is the first record of Cryptocotyle from …
Bolivian Ectoparasites: A New Species Of Laelapine Mite (Acari: Parasitiformes, Laelapidae) From The Rodent Neacomys Spinosus, Donald Gettinger, Scott Lyell Gardner
Bolivian Ectoparasites: A New Species Of Laelapine Mite (Acari: Parasitiformes, Laelapidae) From The Rodent Neacomys Spinosus, Donald Gettinger, Scott Lyell Gardner
Harold W. Manter Laboratory of Parasitology: Faculty Publications
Laelaps neacomydis n. sp. is described from the pelage of the rodent Neacomys spinosus collected in Bolivia. Collection records from northern Brazil, southeastern Peru, and central Bolivia indicate its wide distribution across Amazonas associated with rodents of the genus Neacomys. The formal taxonomic description and illustrations are derived from the adults (female and male). Two larger species of laelapine mites, Gigantolaelaps intermedius and L. boultoni, infest the same hosts at the same localities.

Harold W. Manter Laboratory of Parasitology: Faculty Publications
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 …

Yungasicola Travassosi Gen. N., Sp. N. (Digenea: Dicrocoeliidae: Eurytrematinae) From Two Species Of Grass Mice Of The Genus Akodon Meyen (Rodentia: Muridae) From The Yungas Of Bolivia, Scott Lyell Gardner, Gerardo Perez-Ponce De Leon
Harold W. Manter Laboratory of Parasitology: Faculty Publications
A new species and genus of digenetic trematode of the family Dicrocoeliidae is described from 2 species of grass mice, Akodon fumeus and Akodon mimus, both collected from an isolated area in the eastern part of the Andes mountains or Yungas of Bolivia. This species differs from all known dicrocoeliids in the unique disposition of the vitelline fields, the much less extensive uterus through the body of the worm (extending posteriad only just past the midline), and cecal branches that are generally conspicuous and lined with a thick layer of glandular epithelial tissue.
A New Pinworm, Didelphoxyuris Thylamisis N. Gen., N. Sp. (Nematoda: Oxyurida) From Thylamys Elegans (Waterhouse, 1839) (Marsupialia: Didelphidae) In Bolivia, Scott Lyell Gardner, Jean-Pierre Hugot
A New Pinworm, Didelphoxyuris Thylamisis N. Gen., N. Sp. (Nematoda: Oxyurida) From Thylamys Elegans (Waterhouse, 1839) (Marsupialia: Didelphidae) In Bolivia, Scott Lyell Gardner, Jean-Pierre Hugot
Harold W. Manter Laboratory of Parasitology: Faculty Publications
Didelphoxyuris thylamisis n. gen., n. sp. is described from the caecum of Thylamys elegans (Waterhouse, 1839) (Marsupialia: Didelphidae) collected in the eastern region of the Andes of Bolivia. Didelphoxyuris thylamisis n. sp. differs from the only pinworm described from marsupials in the Neotropics (Neohilgertia venusti Navone, Suriano et Pujol, 1990) in having only three oesophageal teeth, non-operculated eggs, females that are didelphic, and males that possess no preanal papillae. Several other species of pinworms have been described from marsupials in Australia, but all are characterized by possessing a buccal capsule that is strongly cuticularized with inter-radial lamellae. These structures …

A New Species Of Linstowia (Cestoda: Anoplocephalidae) From Marsupials In Bolivia, Scott Lyell Gardner, Mariel L. Campbell
A New Species Of Linstowia (Cestoda: Anoplocephalidae) From Marsupials In Bolivia, Scott Lyell Gardner, Mariel L. Campbell
Harold W. Manter Laboratory of Parasitology: Faculty Publications
A new species of cestode of the genus Linstowia (Cestoda: Anoplocephalidae) is described from marsupials of the genera Thylamys and Monodelphis. The new species (Linstowia schmidti) differs from L. iheringi Zschokke, 1904, in having a much smaller strobila and reduced number of proglottids, and in the distribution of the eggs in gravid proglottids. In Bolivia, cestodes of the genus Linstowia appear to have a restricted geographic distribution, occurring in marsupials only in southeastern Bolivia near the western margin of the Chaco. This host-parasite association may represent an ecological-historical relict.

Parasites As Probes For Biodiversity, Scott Lyell Gardner, Mariel L. Campbell
Harold W. Manter Laboratory of Parasitology: Faculty Publications
Cestodes of the genus Linstowia, parasitic in marsupials, show patterns of coevolution and ancient historical-ecological connections. Correlated with the breakup of the austral landmasses (Gondwanaland) of the Neotropical and Australian regions from the Antarctic continent, the age of this host-parasite community is estimated to be between 60 and 70 million years old. Based on the data from the survey of parasites of mammals from throughout Bolivia and from the phylogenetic analysis of the cestodes, we urge the planners of biodiversity preserves in the neotropics to consider the Yungas of Bolivia as a region that supports an ancient ecological community …

Harold W. Manter Laboratory of Parasitology: Faculty Publications
Of 35 tuco-tucos (Ctenomys opimus) collected in Bolivia, South America, 31 (88%) had eimerian oocysts in their feces at the time they were examined. Eighteen (58%) of the 31 infected animals were concurrently infected with 2 or 3 eimerian species. Four species of Eimeria were recovered and are described as new species based on the characteristics of sporulated oocysts. Oocysts of E. granifera n. sp. were ellipsoidal, 21.1 x 17.2 (15-26 x 11-20), μm with sporocysts ovoidal, 11.3 x 7.1 (8-14 x 5-9), μm. Oocysts of Eimeria montuosi n. sp. were spheroidal, 24.2 x 22.0 (21-28 x …

Echinococcus Vogeli Rausch And Bernstein, 1972, From The Paca, Cuniculus Paca L. (Rodentia: Dayproctidae), In The Departamento De Santa Cruz, Bolivia, Scott Lyell Gardner, Robert L. Rausch, Otto Carlos Jordan Camacho
Harold W. Manter Laboratory of Parasitology: Faculty Publications
Among approximately 2,000 mammals examined for helminths in various regions of Bolivia during 1983-1987, cysts of Echinococcus vogeli Rausch and Bernstein, 1972, were found in a single paca, Cuniculus paca L., collected at La Laguna, Departamento de Santa Cruz (lat. 16° 36' W; long. 62° 42' S). This record, the first from Bolivia, represents a considerable extension of the known geographic range of this species in South America. Upon analysis of the morphologic characteristics of the protoscoleces derived from the cysts, the sizes of rostellar hooks from the material from the paca were found to be well within the ranges …
