Vol. 87, Nos. 7 & 8, September & October 1976 203 A PRELIMINARY LIST OF THE SPIDERS (ARANEAE) OF DELAWARE' } George W. Uetz^'* ABSTRACT: This first published list of Delaware spiders records 199 species in 26 families. Sources of records are; (1) Collections by numerous Delaware entomologists beginning about 1935 identified and recorded by T. A. Parker; (2) Museum collections of the Academy of Natural Sciences in Philadelphia; and (3) Ecological studies of spiders in the University of Delaware Experimental woodlot. Collecting data, including locality and month, are given for all species, and a map is provided showing the collecting localities. DESCRIPTORS: spiders, Araneae, Delaware, Arachnida, Taxonomic lists. Published records of spiders from Delaware are scarce, although Muma (1943, 1944, 1945) has recorded 384 species from the Delaware/Maryland/ Virginia penninsula. T. A. Parker (1965) reported in a senior thesis on 130 species that he and others had collected in Delaware. The material is pre-served in the Department of Entomology and Applied Ecology Museum, and includes specimens collected from about 1935 by several Delaware entomolo-gists. Parker's work is the only list of Delaware spiders to date. I have examined the spider collections of the Philadelphia Academy of Natural Sciences, but most of the additions to Parker's list are from an ecological study I made in 1970 of spiders in the University of Delaware experimental woodlot. Others are from miscellaneous collecting in New Castle County. My collecting was by sweep net, hand sorting of litter and debris, or by pitfall trapping. In the list of species that follows, localities are indicated by numerals which correspond to points on a map of the state (Fig. 1). These are further characterized in a list of locaHties. Also in the list of species, the month (s) in which each species was collected is given, and the sources of records are designated by capital letters as follows: TAP -"Spiders of Delaware"; senior thesis of T.
