The writer has studied spiders in Arkansas from 1966 to the present time with each major Physiographic Region (Pell 1983) of the state being covered to try to determine the spider fauna. These natural regions of Arkansas show significant ecological differences with habitat diversity including mountains, upland hardwoods, bottomland hardwoods, loblolly -shortleaf pine, cedar glade, upland prairie, to caves.
Although no study is definitive, it is intended that this list will be of use to arachnologists and researchers in determining the biodiversity for Arkansas.
This updated checklist of spiders is based on published and unpublished records available to the author. At present, 35 families, 204 genera, and 546 species of spiders have been identified in Arkansas.
Faunal lists of spiders have been compiled since the early 1960's. Whitcomb and his associates conducted many spider studies associated with cotton (Whitcomb et al., 1963a, b; Whitcomb and Bell, 1964; Whitcomb, 1967) and with the fall webworm (Whitcomb and Tadic, 1963). Additional investigations were made by Warren and Tadic (1967) on spider predation of the fall webworm and by Peck et al. (1971) on spiders associated with shortleaf and loblolly pine. Dorris (1970) studied impact of insecticides on spider populations in a cotton field. Studies have also been made of spiders collected from Arkansas blueberries (Johnson and Heiss, (unpublished data) and from rice (Heiss and Meisch, 1985). Dorris (1986 made a preliminary study of spiders collected in pit traps from pine/hardwood forests and Hill, Dorris and Thompson (1995) reported on spiders collected in pit traps in Drew County from different silvicultural systems. These studies include a species list and observations on behavior and habitats.
Spider fauna of the natural areas of Arkansas have been investigated by Dorris, (1968, 1969, 1972, 1980, 1985, 1986, 1989, 1991; Dorris and Burnside, 1977; Beck and Dorris, 1982, 1983; Dorris and Saugey, 1983; Dorris and Burris, 1992; Dorris, Robison, and Carlton, 1995; Parker and Dorris, 1995; Hill, Dorris, and Thompson, 1995). Exline (1962) identified two new gnaphosid spiders, McDaniel et al (1979) and Peck and Peck (1982) have contributed records of species occurring in Arkansas caves, and Dorris and Saugey (1983) investigated spiders occurring in abandoned mines and tunnels.
Taxonomic keys of Kaston (1982), Comstock (1982), and Gertsch (1979) have aided in this study, however, a complete bibliography of the numerous monographs and books used for identification is not included in the literature cited section as it is assumed by the writer that investigators use these common tools for classification of spiders in any area of the world.
It is intended that AN UPDATED CHECKLIST OF THE SPIDERS OF ARKANSAS will fill the existing void of arachnology literature for the state and apprise investigators of the spider fauna of Arkansas.
I am indebted to the following for loan of specimens, collections, and aid of various kinds; Dr. W. J. Gertsch, Dr. Lynne C. Thompson, Dr. Henry Robison, Dr. Chris Carlton, Mr. David Saugey and my colleagues. Appreciation is also expressed to numerous graduate and undergraduate students for various tasks, collections, and identifications. Special gratitude is extended to Mrs. Sherry Smith for aid in compilation of the state list. I should also like to express my appreciation for financial assistance to Henderson State University, The Corps of Engineers, and the Ross Foundation.
Several methods and types of instrumentation were used for collecting and identification. Methods included (a) heavy duty sweep net in grasses and heavy brush, (b) wire mesh for leaf litter, (c) chopping bark from trees, (d) hand picking from bushes, ground, agriculture crops, old dwellings, water and other related places, (e) mud-dauber nests were broken open to reveal paralyzed spiders captured by mud-daubers, (f) night spot-lighting, and (g) pit traps set in the ground to trap spiders traveling across the ground.
Collections from other institutions such as University of Arkansas at Fayetteville, L.S.U. at Baton Rouge and University of Mississippi at Oxford were examined. Data were obtained from collections and publications on Arkansas spiders.
Most collections were made between the hours of 9 A.M. and 5 P.M. The specimens were preserved in screw cap vials containing 75% ethyl alcohol. In all physiographic regions 8-10 check stations were set up across the whole regions so that coverage of the various habitats could be assured.
Microscopic examination of specimens was made using an American Optical dissecting microscope equipped with a 20X20 grid micrometer.
Use of numerous taxonomic keys and monographs have been employed for identifications. Arkansas publications are stressed in this paper with the assumption that investigators using this checklist will be aware of the tremendous numbers of publications related to spider identification. Data from recent publications were included only when the author was a recognized authority or the data could be verified by examination of the original specimens.
Spiders are listed alphabetically in an attempt to expedite the search for families, genera and species.
Multiple studies of the spider fauna made by Dorris (1968-1995) and other investigators in Arkansas have been compiled into a list of 35 families, 204 genera, and 546 species collected from diverse ecological habitats including mountains, river valleys, pine-hardwood forests, mine tunnels, coastal plains and agricultural crops. The purpose was to achieve a composite checklist of all identified spiders occurring in Arkansas.
