U.S.A. (Arizona, New Mexico) 2007
10–13 October, 2007: Funded by the REVSYS grant. Volunteer Kari McWest travelled to the "bootheel" of New Mexico and Cochise County, Arizona, planning to collect vaejovid species from the mountains in that region and, with volunteer Manny Rubio, to investigate the unsampled Mule Mountains at Bisbee. McWest flew into El Paso and rented a car. In New Mexico, he visited the Florida and Little Florida mountains near Deming, the Big Hatchet Mountains, and Granite Gap and Antelope Pass in the Peloncillo Mountains. The scorpions collected here included Centruroides sculpturatus, Vaejovis coahuilae and Superstitionia donensis. McWest and Rubio met up in Bisbee and traveled to the Mule Mountains, where they collected several Centruroides sculpturatus, the only scorpion species previously reported in these mountains, and a single female vaejovid. On the way back to El Paso, McWest collected numerous specimens of very small Vaejovis spinigerus on the highway pavement. Granite Gap and Antelope Pass were also visited again in attempts to find Serradigitus agilis and additional specimens of Vaejovis.
June 2007: Funded by the American Tarantula Society (ATS). Volunteer Kari J. McWest and his children Hunter Burrell and Malea McWest travelled to the 10th Annual American Tarantula Society Conference in Phoenix, AZ. Accompanied by members of the ATS, they collected Serradigitus wupatkiensis near the type locality, several "forms" of Vaejovis spinigerus, V. confusus, V. aff. paysonensis, Hadrurus arizonensis and Centruroides sculpturatus. On the return trip, they visited several forested mountains in search of Vaejovis vorhiesi relatives and were largely unsuccessful, with the exception of two specimens collected near the Arizona/New Mexico border.
