The Genus Haemolaelaps (Acarina: Laelapidae) In The Northwest Ethiopian Biogeographical Region, Calvin J. Sakamoto

Theses and Dissertations

This paper presents the results of a taxonomic stury of mites of the genus Haemolaelaps collected from small mammals of 8 political subdivisions of the northwest portion of the Ethiopian Biogeographical Region. Specimens taken from 2,863 small mammals from a wide variety of habitats and localities were examined. The Haemolaelaps fauna includes 23 species, 10 of which are described as new: H. bellasoma, H. caurinus, H. chaetospinicus, H. crocidura, H. desmodilliscus, He. ebsi, H. malachela, H. parahirsti, H. sikapusi and H. taterakempi. Numerical taxonomic and multicariate analyses were used to assess variation and clustering. A key for identification of females …

Venezuelan Macronyssidae (Acarina:Mesostigmata), Robert C. Saunders

Theses and Dissertations

A total of over 5000 mite specimens representing 49 species was studied and evaluated. The most frequently encountered species was Ornithonyssus bacoti. Based on these specimens, a brief review of the family Macronyssidae in Venezuela is presented. Included are brief notes as to medical importance and host relationships; also a key to the genera of Venezuelan Macronyssidae and a host-parasite list are included. Reprints of two papers and the manuscript of a third are included as part of the dissertation requirements. Contained in these are descriptions of three new genera (Argitis, Lepidodorsum, and Nycteronyssus) and four new species (Acanthonyssus proechimys, …

Taxonomic Studies Of Trombiculid Mites, Jack T. Reed

Theses and Dissertations

Five publications and one manuscript concerning the taxonomic studies of trombiculid mites are submitted. Publications include a revision of the North American genus Comatacarus Ewing, the erection of the following genera by Brennan and Reed: Loomisia, Atelepalme, Phalcophila, and Nycterinastes. Discussions of the genera Aitkenius Brennan and Polylopadium Brennan and Jones are also included. The subfamily Leeuwenhoekinae is reviewed on the basis of neo-tropical representatives (unpublished manuscript). The genus Odontacarus comprises 66% of the chiggers examined, and 82% of these were identified as O. tubercularis (Brennan). Odontacarus fieldi Brennan and Jones and O. cayolargoensis Brennan are synonomized under O. tubercularis …

Mites On Kangaroo Rats At The Nevada Test Site, Morris A. Goates

Brigham Young University Science Bulletin, Biological Series

A systematic study of parasitic mites on kangaroo rats of two species at the Nevada Test Site was conducted from August 1959 to December 1961. The intent was to determine the kinds, numbers, seasonal occurrences and ecological relationships of mites in nuclear disturbed and contiguous undisturbed areas. A total of 1,256 rats from nine plant communities was examined.

The 6,208 mites collected represented 16 species including four undescribed. Fourteen were found on both kinds of rats. Considerably more rats were infested with chiggers than with mesostigmatids. Each species of mite occurred alone on its host at least 20% of the …

The Incidence Of Nasal Mites In Over-Wintering Red-Wing Blackbirds In The Vicinity Of Utah Lake, Utah, George M. Talley

Theses and Dissertations

This paper reports the incidence and associations of four species of mites, Paraneonyssus icteridius, Ptilonyssus n. sp. "A", Sternostoma n. sp. "A" , and Speleognathus sp., found in the nasal cavities of the common red-wing blackbird (Agelaius phoeniceus ssp.) and Brewer's blackbird (Euphagus cyanocephalus cyanocephalus Wagler) over-wintering in the vicinity of Provo, Utah County, Utah. Three species of mites are reported for the first time from these birds, and two of these three are undescribed species.
