The Streblid Batflies Of Venezuela (Diptera: Streblidae), Rupert L. Wenzel Jun 1976

The Streblid Batflies Of Venezuela (Diptera: Streblidae), Rupert L. Wenzel

Brigham Young University Science Bulletin, Biological Series

This study was based on more than 36,000 Venezuelan Streblidae representing ca. 115 species and species complexes in 22 genera, taken from more than 6,800 hats of 95 species. Two new genera are proposed and 45 new species are described. The morphology is briefly discussed and terminology is revised. Collection data are given for each species, together with discussions on variability and host relationships when pertinent. Keys to genera and species arc included, as well as illustrations of most species. Noctiliostrebla dubia (Rudow) and the male of Parastrebla handleyi Wenzel are characterized, and relationships of Speiseria are discussed ...

Spinturnicid Mites Of Venezuela (Acarina: Spinturnicidae), C. Selby Herrin, Vernon J. Tipton Oct 1975

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 ...


Systematics Of Neotropical Hirstionyssus Mites With Special Emphasis With Special Emphasis On Venezuela (Acarina: Mesostigmata), C. Selby Herrin, Conrad E. Yunker Oct 1975

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 ...


Mallophaga Of Venezuelan Mammals, K. C. Emerson, Roger D. Price Sep 1975

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 ...

A Comparison Of Meteorologic Measurements From Irrigated And Non-Irrigated Plots, Provo, Ut, 1970–1972, Ferron L. Andersen, Phil D. Wright, J. Carl Fox Apr 1974

A Comparison Of Meteorologic Measurements From Irrigated And Non-Irrigated Plots, Provo, Ut, 1970–1972, Ferron L. Andersen, Phil D. Wright, J. Carl Fox

Brigham Young University Science Bulletin, Biological Series

A comparative study of micrometeorologic conditions on irrigated and non-irrigated pasture plots was conducted at Provo, Utah, from 1970 to 1972. Daily measurements were taken of the following: precipitation cither as rain or snow, new snowfall and total snow depth during the winter; relative humidity in a standard weather shelter; number of hours at maximum relative humidity; cloud cover each morning; potential evaporation; total wind 1 m above ground level; temperature extremes in a standard weather shelter; and temperatures both on irrigated and non-irrigated plots with sensing devices located 5 cm beneath soil surface under grass cover, at soil surface ...

A Taxonomic Study Of The Western Collared Lizards, Crotaphytus Collaris And Crotaphytus Insularis, Nathan M. Smith, Wilmer W. Tanner Apr 1974

A Taxonomic Study Of The Western Collared Lizards, Crotaphytus Collaris And Crotaphytus Insularis, Nathan M. Smith, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

The heterogeneous nature of the collared lizards west of the Colorado River prompted this study. Samples from known populations of C. c. auriceps, C. c. baileyi, and C. c. fruscus were used as a base for defining the western populations. External morphology and cranial morphology were compared by cluster, canonical, and discriminant analyses.

Results of these analyses show a western complex of four populations which are distinct from the three base populations of the collaris complex. Members within the western complex are distinguishable with at least 90 percent reliability by discriminant analysis. Because of intergradation patterns seen in western Sonora ...
