  1. Southwestern USA, July 2008:Southern ArizonaSouthwestern New Mexico Kari J. McWest and Hunter M. Burrell

  2. Kari and his 13-year-old son, Hunter, traveled from Canyon, Texas to Rio Rico/Nogales, Arizona, to collect scorpions and other arachnids for REVSYS and GSIS on their way to attend the Tenth Annual Conference of the American Tarantula Society. They targeted undocumented localities that might harbor montane Vaejovis species—including Vaejovis vorhiesi—and to attempt collection of elusive species on the REVSYS list.

  3. The first leg of our route took us from Canyon, Texas, to Socorro, New Mexico, to search for material in the San Mateo Mountains. Along the way, we unsuccessfully sampled in several locations. In the Tularosa Basin, however, we collected Vaejovis coahuilae (bottom right) and Paruroctonus gracilior with an unusual carapace pattern: the interocular triangle is usually dark with the posterior region of the carapace light. This specimen shows the opposite: A pale interocular crescent.

  4. After a successful collection of an undescribed Vaejovis in the San Mateo Mountains near Socorro, we moved on to this area near the New Mexico/Arizona border. I had been here several times in the past at night, but had no idea the terrain was suitable for Vaejovis cf paysonensis because I simply couldn’t see the forest and outcroppings from the road. Previous visits to localities within a few miles in either direction of this spot yielded only Centruroides sculpturatus and large Vaejovis spinigerus.

  5. Attempts to collect in the Galiuro Mountains were unsuccessful. The road was slow and difficult, while rain clouds loomed on the horizon, so we could only sample for a limited time to avoid getting trapped. Much of the road was in a stream bed, which we crossed many times. On the way out, however, night fell and we were able to sample the flats below the Galiuro and Pinaleño mountains.

  6. Undescribed Aphonopelma sp. Vaejovis spinigerus Vaejovis confusus Arizona elegans, glossy snake Vaejovis crassimanus

  7. Diplocentrus spitzeri is a common scorpion in Santa Cruz County, Arizona. This male was found by Mike “troll” Dame of the American Tarantula Society behind our conference hotel, the Esplendor Resort. Ichen Shen and Sara Black of Canyon, Texas, chasing a mutillid in Rio Rico. Shasta East and David Sissom

  8. Mule Mountains, Bisbee, Arizona. Very large Echinocereus pectinatus, rainbow cactus Vaejovis cf vorhiesi Centruroides sculpturatus Hunter’s cell phone, wedged in the granite!

  9. Barbara Roth’s footbridge over Cave Creek in Portal. We visited Portal and the Southwestern Research Station in the Chiricahua Mountains between collecting regions in Cochise County, Arizona and Hidalgo County, New Mexico.It rained.A Lot. Hypsiglena torquata (I was really hoping to find one of these to show Hunter, it’s one of my favorite snakes!) Cave Creek at SWRS. Pituophus catenatus

  10. Echinocereus fendleri Granite Gap and Peloncillo Mountains,New Mexico. An undescribed species in the area remains elusive. Vaejovis spinigerus Centruroides sculpturatus Vaejovis coahuilae, near Animas

  11. We attempted more daytime collecting in SW New Mexico and in the Florida Mountains: unsuccessful. Lordsburg Playa was full from the recent heavy rains.

  12. While in Deming, we noticed the mountains to our north, the Cookes Range, elevation about 8,400 feet (2560 m). Let’s go check them out. Mammilaria heyderi

  13. It took us about two hours of searching to find this unknown Vaejovis, with another two hours spent afterwards: no such luck.

  14. Echinocereus fendleri Vaejovis crassimanus from flats below Cookes Range Crotalus atrox Phrynosoma hernandesi, greater short-horned lizard
