U.S.A. (northeast Arizona) 2008

29–30 August, 2008: Funded by the REVSYS grant. REVSYS volunteer, Zach Valois (undergraduate, Salt Lake Community College) and friend, Kelsey Neeley obtained athe appropriate permits and traveled over 1,250 miles to successfully sample scorpion populations in the Chuska Mountains, an important locality on the Najavo Indian Reservation in Apache County, Arizona.  Several points in New Mexico were also explored without success. The montane theraphosid, Aphonopelma behlei was also found. At over 9,000 ft., this record represents one of the highest records to date for the species. This trip yielded some important specimens that will fuel future work in the area, especially in understanding speciation in A. behlei.
