Journal of the Arkansas Academy of Science, Vol. 39 [1985], Art. 10 A CHECK-LIST OF THE SPIDERS OF ARKANSAS PEGGY RAE DORRIS Henderson State University Arkadelphia, AR 71923 ABSTRACT Collections of spiders were made from 1966, to the present in the sixphysiographic regions of Arkan- sas. During this time 435 species representing 35 families were collected and recorded. INTRODUCTION mixed grasses, fields ofmixed grasses, shrubs, herbs, mud-dauber nests, and water surfaces. The number ofspecimens decreased as temperature Research has been in progress for the past 18 years to provide a and humidity increased. checklist of Arkansas spiders. Dorris (1968, 1969, 1970, 1971, 1972, Figure 1, Pell(1983), represents the six physiographic regions covered 1980); Dorris and Burnside (1977); Beck and Dorris (1983); and Dorris in this study. Itis the belief ofthis author that at least 90% ofthe spider and Saugey (1983); made numerous studies in an effort to cover the fauna of Arkansas has been identified. The Arkansas spider checklist major physiographic regions ofthe state. Whitcomb, Exline, and Hite of species follows and common names are employed where known. (1963); Whitcomb and Tadic (1963); Whitcomb and Bell (1964); and Warren, Peck, and Tadic (1967) made arthropod studies in agricultural habitats of the Ozark Mountain Area. Heiss (1977) collected specimens from pit traps located in two counties of the Ozark Mountain Area. The six physiographic regions of Arkansas as defined by the En- vironmental and Conservation office of the Department of Education, show significant ecological differences withhabitat diversity including mountains, upland hardwoods, bottomland hardwoods, loblolly- shortleaf pine, cedar glade, upland prairie, to caves. The purpose of this lengthy study has been to determine the spider fauna of Arkansas. Itis the authors opinion that at least 90% of the species have been identified, while recognizing that an ecological study of this scope can rarely be definitive. METHODS AND MATERIALS Several methods and types of instrumentation for collecting wereused. They were (a) heavy duty sweep net in grasses and heavy brush, (b) wire mesh for leaf litter, (c) chopping bark from trees, (d) hand pick- ing from bushes, ground and old dwellings and other related places, (e) mud-dauber nest collections to reveal paralyzed spiders captured by mud-daubers, (f)night spot-lighting. Pit traps were used extensive- ly inDrew County and Heiss (1977) also employed this sampling tech- nique. Collections from other institutions such as University of Arkansas at Fayetteville and L.S.U. at Baton Rouge were examined. Most of the collections were made between the hours of 9 A.M.and 1 OZARK MOUNTAINS NATURAL DIVISION 5 P.M.
