Sociobiology, Vol. 49, No. 2, 2007 Ants of the Idaho National Laboratory By William H. Clark & Paul E. Blom SOCIOBIOLOGY is a serial published by the Department of Biologi- cal Sciences of California State University, Chico 95929-0515, U.S.A. It is published in volumes of a minimum of 320 pages and it is printed and dis- tributed in paper bound fascicles as manuscripts and finances permit. There are usually 3 fascicles per volume. The (2007) price of each volume is $75.00 U.S. There are 2 volumes per year therefore a subscription is $150.00. Pay- ment by credit card is encouraged. Prices for individual fascicles are provided upon request. A fee is added to overseas subscriptions to partially cover the additional mailing costs for delivering such subscriptions. The serial is devoted to papers giving research results, review articles, or translations of classic papers on any aspect of the biology of social animals. We are primarily interested in quality articles which will print out at 30 pages or more but we will accept quality articles of any length. Papers intended for publication should be sent to the editor: Dr. David H. Kistner Dept. of Biological Sciences California State University Chico, CA 95929-0515, U.S.A. email: [email protected] Home Page: http://www.csuchico.edu/biol/Sociobiology/sociobiologyindex.html Manuscripts should follow the recommendations of the most recent edi- tion of the CBE Style Manual, published by the Council of Biology Editors, Inc., 9650 Rockville Pike, Bethesda, MD 20814, except for the bibliography wherein journal citations should be spelled out completely. Line drawings should be reduced to a width of 4.5 inches (28 picas, or approximately 11.43 cm). The use of good illustrations is encouraged. Complex formulae should be submitted in camera-ready form as line drawings. All figures must be referred to in the text. SOCIOBIOLOGY continues as a journal where research results can be published at modest cost. Page charges (2007) are a modest $12.00/printed page. Even these modest charges are dropped if reprints are ordered. Reprint costs are competitive with similar costs of other journals. Manuscripts should be accompanied by electronic versions on IBM formatted disks preferably as rtf files.

Annotated Checklist of the Ants on the Idaho National Laboratory (Hymenoptera: Formicidae) by William H. Clark1 & Paul E. Blom2, 3 Abstract Many invertebrates, including ants, tunnel and nest in soils. Because of these habits they are potentially important at the Idaho National Laboratory (INL) where they may tunnel into and disturb buried waste. Ants are very important components of the desert ecosystem based on their distribution, habitat preferences, food habits, and relative abundance. For these reasons the ant taxa present at the INL were investigated. A cursory survey of the ants at the site was published in 1971 which reported 22 species. A more thorough examination was needed. Our research in the northeastern portion of the Snake River Plain at the INL from
