Systematics Of Neotropical Hirstionyssus Mites With Special Emphasis With Special Emphasis On Venezuela (Acarina: Mesostigmata), C. Selby Herrin, Conrad E. Yunker
Systematics Of Neotropical Hirstionyssus Mites With Special Emphasis With Special Emphasis On Venezuela (Acarina: Mesostigmata), C. Selby Herrin, Conrad E. Yunker
Brigham Young University Science Bulletin, Biological Series
This paper presents the results of a systematic study of mites of the genus Hirstionyssus Fonseca collected from mammals, primarily in Venezuela, but including one collection each from Colombia, Nicaragua, and British Honduras. Previously described species from Panamá and Brazil are reviewed and new distributional records are listed. The known Neotropical fauna of Hirstionyssus mites includes 15 species, 7 of which are described here as new: H. proctolatus n. sp.; H. brachysternum n. sp.; H. dorsolatus n. sp.; H. rhipidomys n. sp.; H, venezuelensis n. sp.; H. brevicalcar n. sp.; and H. parvisoma n. sp. The previously unknown male and …

Spinturnicid Mites Of Venezuela (Acarina: Spinturnicidae), C. Selby Herrin, Vernon J. Tipton
Brigham Young University Science Bulletin, Biological Series
The results of an extensive survey of spinturnicid mites of bats from Venezuela are presented in this paper. Approximately 30,000 bats were collected from a wide variety of life zones and localities. A representative sample was searched for ectoparasites. There are 3 genera of the family Spinturnicidae in Venezuela: Cameronieta, Periglischrus, and Spinturnix. Three previously described species of Cameronieta were found in the Venezuelan collection. Of the 7 species of Spinturnix previously described from the New World, 4 are reported from Venezuela. The genus Periglischrus constitutes by far the most significant segment of the Venezuelan collection. It is represented by …

Distribution And Abundance Of The Black-Billed Magpie (Pica Pica) In North America, Carl E. Bock, Larry W. Lepthien
Distribution And Abundance Of The Black-Billed Magpie (Pica Pica) In North America, Carl E. Bock, Larry W. Lepthien
Great Basin Naturalist
Analysis of Audubon Society Christmas bird count data and certain environmental variables shows the degree to which the Black-billed Magpie is a bird of cool arid regions in North America. The abundance and distribution of this species appear to be limited by two major climatic barriers: increasing summer temperatures in the Southwest and increasing summer humidity and precipitation on the central plains.
Mallophaga Of Venezuelan Mammals, K. C. Emerson, Roger D. Price
Mallophaga Of Venezuelan Mammals, K. C. Emerson, Roger D. Price
Brigham Young University Science Bulletin, Biological Series
Seven species of Mallophaga have been previously reported from Venezuelan mammals. In this paper an additional 28 species and subspecies, 7 of which are new, are reported from Venezuela; and 21 other species which have not been previously reported from Venezuela are included because their hosts are found there.

The Subfamily Leeuwenhoekinae In The Neotropics (Acarina: Trombiculidae), Jack T. Reed, James M. Brennan
Brigham Young University Science Bulletin, Biological Series
Neotropical representatives of the subfamily Leeuwenhoekinae are reviewed. The genus Odontacarus comprises 66 percent of the chiggers examined, and 82 percent of this genus were identified as O. tubercularis (Brennan). The following genera are redescribed: Albeckia Veracammen-Grandjean and Watkins, Leeuwenhoekia Oudemans, Odontacarus Ewing, Sasacarus Brennan and Jones, Wagenaaria Brennan, and Whartonia Ewing. New taxa are: Odontacarus comosus comosus, O. c. novemsetus, O. dienteslargus, O. pugnosus, O. schoenesetosus, O. sunnianae, O. tiptoni, O. tuberculohirsutus, O. vanderhammeni, O. vergrandi, Sasacarus furmani panamensis, and Whartonia angulascuta. Odontacarus fieldi Brennan and Jones, 1961, and O. cayolargoensis Brennan, 1959, are synonymized under O. tubercularis Brennan, …

Mississippi Flora. Iv. Dicotyledon Families With Aquatic Or Wetland Species, Samuel B. Jones Jr.
Mississippi Flora. Iv. Dicotyledon Families With Aquatic Or Wetland Species, Samuel B. Jones Jr.
Gulf and Caribbean Research
The first paper in this series treated some of the monocotyledon families with aquatic or wetland species (Jones 1974). The primary aim of this paper is to improve our knowledge of some of the dicotyledon families with aquatic and wetland plants in Mississippi. Hopefully, this paper will be reviewed and criticized by many, and corrected before the proposed Guide to the Flora of Mississippi is published.

Some New Or Otherwise Noteworthy Plants Of The Arkansas Flora, Edwin B. Smith, Barney L. Lipscomb
Journal of the Arkansas Academy of Science
During the last several years interesting additions have been made to the holdings of the University of Arkansas Herbarium at Fayetteville. A list of 24 species of vascular plants, new or rare in Arkansas, is presented. Many of these were collected by the second author during research for his Master's degree.

Castanea Pumila Var. Ozarkensis (Ashe) Tucker, Comb. Nov, Gary E. Tucker
Castanea Pumila Var. Ozarkensis (Ashe) Tucker, Comb. Nov, Gary E. Tucker
Journal of the Arkansas Academy of Science
Castanea ozarkensis Ashe, the Ozark chinquapin of the vascular plant family Fagaceae, is distributed widely throughout the Interior Highlands of Arkansas and the adjacent states of Missouri and Oklahoma. Examination of material from throughout the range of C. ozarkensis indicates demonstrable morphological intergradation with C. pumila (L.) Miller sensu lato, the chinquapin of wide distribution in much of the eastern United States. It is proposed that C. ozarkensis be reduced to C. pumila var. ozarkensis (Ashe) Tucker, comb. nov.
