Fleas (Siphonaptera) Associated With Small Mammals Of Morocco Their Distribution And Host-Specificity, Michael W. Hastriter
Fleas (Siphonaptera) Associated With Small Mammals Of Morocco Their Distribution And Host-Specificity, Michael W. Hastriter
Theses and Dissertations
A total of 9,936 fleas, representing 27 species, have been processed for study and identified. They were associated with 2,011 small mammals, representing 38 species, collected throughout Morocco from October 12, 1969 to July 20, 1970 by personnel of the Smithsonian Institution. Two species, Synosternus cleopatrae pyramidis (Rothschild and Xenopsylla ramesis (Rothschild), comprised 68 percent of the fleas collected. Two subspecies are described: Ctenophthalmus andorrensis opistolatus, ssp. n. and Ctenophthalmus russulae tangerensis, ssp. n.. There are three ecological subdivisions of Morocco: the coast and coastal plains, the Atlas Mountains, and the pre-saharan desert. Even though there is some overlap, the …

This publication presents the results of an extensive survey of symbiotic laelapid mites of vertebrates from Venezuela. Over 40,000 vertebrates were examined from a wide variety of life zones and localities. The laelapid fauna represented includes 1 new genus, Hymenolaelpas, and 7 genera previously described: Laelaps, Mysolaelaps, Tur, Steptolaelaps, Neoparalaelaps, Gigantolaelaps, and Androlaelaps. The genera are represented by 51 species and subspecies, of which 8 are described as new. Previously unknown males and immatures of several species are described. Gigantolaelaps versteegi ( Oudemans ) is redescribed from type material; G. wolffsohni (Oudemans) is redescribed from Oudemans’ original material; G. peruviana …

Venezuelan Nycteribiid Batflies (Diptera: Nycteribiidae), Lindolpho R. Guimarães
Venezuelan Nycteribiid Batflies (Diptera: Nycteribiidae), Lindolpho R. Guimarães
Brigham Young University Science Bulletin, Biological Series
Eleven species of Nycteribiidae, all belonging to the genus Basilia, are reported from Venezuela. Of these, two (tuttlei and typhlops) are described as new and four (anomala, dubia, juquiensis, and tiptoni) are recorded for the first time. B. anomala is the first species with three tergal plates to be found in South America. Synonymies, previous localities, and host records are given for all species, as well as new records and comments. Geographical distribution and host-parasite associations are discussed. Field parties of the Smithsonian Venezuelan Project obtained the material on which this paper is based.

Helminths Of Sceloporus Lizards In The Great Basin And Upper Colorado Plateau Of Utah, Richard Carlyle Pearce
Helminths Of Sceloporus Lizards In The Great Basin And Upper Colorado Plateau Of Utah, Richard Carlyle Pearce
Theses and Dissertations
This study was prompted by the scarcity of information on helminths in Sceloporus lizards of Utah. It reports these worms and includes references to parasites of reptiles in the appendix. A microscopic examination of the coelom, mesenteries, liver, lungs, esophagus, stomach, and intestines of 55 lizards was made, but helminths were recovered only from stomachs and intestines. Examination of S. graciosus yielded Opchoristica scelopori, a cestode found in the duodenum, and Cyrtosomum penneri, C. readi, and C. heynemani, three nematodes of the cecum. The latter two are new nematodes for this host species. Examination of S. undulatus yielded three new …
Characterization Of Field Populations Of Magarites Pupillus (Gould) (Gastropoda, Prosobranchia), Stephen Craig Schroeter
Characterization Of Field Populations Of Magarites Pupillus (Gould) (Gastropoda, Prosobranchia), Stephen Craig Schroeter
Theses and Dissertations
Field populations of Margarites pupillus (Gould), a numerically abundant prosobranch mollusc occuring on rocky shores in Puget Sound, Washington, have previously received little autecological attention. Seawater table studios and SCUBA observations led to the following conclusions: Populations of Margarites are primarily subtidal. Population density and growth are directly related to algal canopy density. Algal canopy may function in reducing predator efficiency, Margarites populations have a 1:1 sex-reatio and no size dimorphism. Sexually mature individuals live for at least two years, and possibly more than four years.
