The redescription, illustrations, and photographs are based upon male and female type specimens as well as a pair of more recently collected specimens from a relatively nearby location; both in Jalisco, Mexico. The genitalia are illustrated for the first time. A distribution map is provided with all verified records from iNaturalist included from: Aguascalientes, Jalisco, Guanajuato, Querétaro, Michoacán, Estado de México, Ciudad de México, Hidalgo, and Puebla. All available knowledge on the natural history is presented including biogeography and distribution, local distribution and habitat use, influence of physical factors, and interspecific relations.

Research paper thumbnail of Mygalomorph spiders from southwestern Oregon, USA, with descriptions of four new species

Zootaxa, 2005

Extensive pitfall trapping in the Siskiyou and southern Cascade Mountains in southwestern Oregon,... more Extensive pitfall trapping in the Siskiyou and southern Cascade Mountains in southwestern Oregon, USA, revealed the presence of four new species of Antrodiaetus spiders (Antrodiaetidae) as well as numerous examples of the rarely reported Hexura rothi (Mecicobothriidae). The new species are: Antrodiaetus ashlandensis, A. coylei, A. effeminatus, and A. metapacificus. Additional records were also obtained for Antrodiaetus pugnax and Atypoides gertschi (Antrodiaetidae). Distributional data are provided for each species. The four new species are described and illustrated and a taxonomic key to all mygalomorph spiders from southwestern Oregon is provided. Further, each of the previously described Antrodiaetus spp. from the region is diagnosed. The morphology of the male genital plate is proposed as a potentially useful taxonomic character.

Information on the biology and ecology of these species is needed to support assessments of threats and to provide recommendations for conservation actions. The objective of this study was to determine the adult phenologies of the nine focal species. Seven semi-permanent insect collecting stations were established in March and April 2013 at the Monahans Sandhills State Park on open and vegetated sand dunes. At each station, a Townes trap, 10 pitfall traps and a UV light trap were used to collect insects; samples from each station were collected at biweekly intervals (monthly on two occasions) through December 2013. Based on trap captures, phenolog...

Research paper thumbnail of Survival of the Red Imported Fire Ant (Hymenoptera: Formicidae) on the Texas High Plains

Environmental Entomology, 1992

An isolated population of the red imported fire ant, Solenopsis invictu Buren, was discovered in ... more An isolated population of the red imported fire ant, Solenopsis invictu Buren, was discovered in Lubbock, TX, during August 1985. This find represented the northwesternmost known population in North America, and it had survived since at least 1983. Preceding the 1985-1986 winter, 207 colonies were located and marked, and 85.4% of the colonies survived until the following spring. Of 277 colonies located before the 1986-1987 winter, 47.8% survived until March 1987. Colonies found near brick walls and roadside, concrete curbs were 89.5 and 80.2%, respectively, of the numbers found at the same locations the previous fall. These percentages are significantly greater than those of colonies found in open, more exposed areas (40.0%). T h e larger number of overwintering colonies found near human-made structures may have been the result of colony survival d u e to greater insolation and consequently warmer soil temperatures than those in open areas. However, the larger number of surviving colonies could have been a manifestation of location preference resulting from repeated colony movements. Only after persistent and aggressive intervention through the use of insecticides was the population eliminated.

Research paper thumbnail of Phalangids (Arachnida: Opiliones) Associated with Strip Clearcut and Dense Spruce-fir Forests of Maine 1

Environmental Entomology, 1984

Five genera and at least seven species of phalangids were collected by pitfall traps in a spruce ... more Five genera and at least seven species of phalangids were collected by pitfall traps in a spruce budworm-infested forest in northern Maine. More than 90% of the specimens were Leiobunum calcar (Wood). Significantly more individuals and species were trapped in uncut residual strips and in dense spruce-Eir stands than in clearcut strips. Peaks in seasonal activity for both individuals and species coincided with spruce budworm egg and early larval stages. Species diversity indices were low; individuals were distributed unevenly among the forest conditions investigated. However, coefficients of community (CC) and percentage similarity (PS) generally were >80% for strip clearcuts (both uncut residual and clearcut strips) and dense stands. Greater disparities (i.e., lower CC and PS percentages) were noted among uncut residual and clearcut strips. Neither age of strip clearcut (1 to 6 years) nor depth of litter had much influence on mean catches and mean numbers of species of phalangids per trap per week. PHALANGIDS or harvestmen are predatory arachnids that feed on a variety of invertebrates, chiefly insects (Bishop 1949, Edgar 1971 and references cited therein). They are also scavengers and feed on dead insects (Todd 1950). Although phalangids attack and feed on lepidopterous larvae, pupae, and adults, little is known of their importance as predators of the spruce budworm, Choristoneura fumiferana (Clemens). Information is also sparse on the species of phalangids associated with spruce-fir forests of Maine. Banks (1902) listed five species from Mt. Katahdin, Piscataquis County, Maine. Procter (1946) listed seven species from various habitats on Mount Desert Island, Hancock County, Maine. In 1977 and 1978, we investigated the epigeal phalangid fauna of strip clearcut and dense sprucefir forests of northern Maine. Our objectives were: 1 ) to determine the species of phalangids found in uncut residual strips, clearcut strips, and dense (control) spruce-fir stands, 2) to determine their seasonal activity as related to spruce budworm development, and 3) to determine if strip clearcutting influenced the diversity and evenness of phalangid species.
