Research Note: Hymenolepis Horrida (Cestoda: Hymenolepididae) And Catenotaenia Peromysci (Cestoda: Anoplocephalidae) In Voles From The Canadian Rockies, Yeen Ten Hwang, Scott Lyell Gardner, John S. Millar

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Cestodes from Clethrionomys gapperi (n=34) and Microtus longicaudus (n=8) from Kootenay National Park, British Columbia, Canada are reported. Two species of cestodes, Hymenolepis horrida (sensu lato) and Catenotaenia peromysci, were found in Clethrionomys gapperi, and one species of cestode, H. horrida, was found in Microtus longicaudus. Clethrionomys gapperi represents a new host record for C. peromysci. The Canadian Rockies is a new locality record for both cestode species.

Arthropod And Helminth Parasites From The Plains Pocket Gopher, Geomys Bursarius Bursarius From The Hosts' Northern Boundary Range In Minnesota, Monroe H. Bartel, Scott Lyell Gardner

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

As part of a continuing and more general study of the diversity of parasites from subterranean mammals in central North America, individuals of the Plains pocket gopher, Geomys bursarius bursarius, were collected from 7 localities in northwestern Minnesota from September 1991 through October 1996. Arthropods collected included the fleas, Opisocrostis bruneri (4 of 124, 3.20/0), Foxella ignota ignota (85 of 124, 68.50/0); the chewing louse, Geomydoecus geomydis geomydis from 98 of 124 (790/0), and larvae of the tick, Dermacentor variabilis (1 of 124, 0.8%). Nematodes found included Physaloptera limbata (2 of 118 gophers, 1.7%), Capillaria americana (4 of 118, …

A New Species Of Linstowia (Cestoda: Anoplocephalidae) From Marsupials In Bolivia, Scott Lyell Gardner, Mariel L. Campbell

Harold W. Manter Laboratory of Parasitology: Faculty and Staff 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 Linstowia 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 and Staff 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 …

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 and Staff 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 [degrees] 36' W; long. 62 [degrees] 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 …

Cestode Parasites Of Some Venezuelan Stingrays, Monte A. Mayes, Daniel R. Brooks

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Forty-seven stingrays representing 8 species collected in Venezuelan coastal waters were examined for cestode parasites. Specimens of 18 tetraphyllidean, lecanicephalidean, and trypanorhynchan cestode species were collected, 3 described as new. Rhinebothrium margaritense sp. n. from Dasyatis guttata and D. americana most closely resembles R. spinicephalum and R. tetralobatum but differs by having 3-6 rather than only 2 testes per proglottid and a different number of bothridial loculi. Rhodobothrium paucitesticulare sp. n. from Rhinoptera bonasus possesses fewer than half as many testes per proglottid as any other known member of the genus. Dioecotaenia campbelli sp. n. differs from D. cancellata by …

A List Of Cestode Parasites From California Mammals, Marietta Voge

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

This report brings together information on the occurrence and distribution of cestode parasites in California mammals. The original information reported herein, was obtained by students, myself, and other staff members of this university. Although the host-parasite list which follows is far from complete, the dearth of knowledge about the helminth fauna in California seems to justify the publication of relatively few data, in the hope that other workers will be able to use this list as a starting point and add to it.

With few exceptions, the common names of the hosts, as given in the host list, were obtained …

A Revision Of The Cestode Family Proteocephalidae, George Roger La Rue

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Introduction

Several years ago while studying under Professor Henry B. Ward .at the University of Nebraska the writer began an investigation of a cestode parasitic in Amblystoma tigrinum (Green). That investigation resulted in a paper (La Rue 1909) in which a number of points in the anatomy of Proteocephalids were cleared up and certain problems were -outlined for investigation at an early date. In the meantime the writer became interested in the large number of Proteocephalids which Professor Ward had secured by work in the field and by exchange. The writer had also made some collections. A preliminary study of …
