Mexico (Oaxaca) 2006
19–30 June, 2006: Partially funded by the NSF REVSYS grant.Oscar F. Francke, Hector Montaño, Carlos Santibáñez, Alejandro Valdez, and Gabriel Villegas participated in this trip, the main targets for which were several new and rare species of Vaejovis from the Sierra Madre Occidental in south-central Oaxaca. The team first traveled to Oaxaca City to pick up Carlos Santibañez, who lives there, and had identified some potential new areas and new taxa for collection. The first night yielded one of the target species, Vaejovis nigrofemoratus, close to Oaxaca. The following nights, the team camped and collected in the mountains southwest of Miahuatlan, where good series of two vaejovid species were collected: a small Vaejovis with a subaculear spine, and a member of the Vaejovis occidentalis complex. Several species of Centruroides (Buthidae) and Diplocentrus (Diplocentridae), some of which are probably new, were also collected. The team then crossed a rough part of the Sierra between Miahuatlan and Juquila, where they collected Centruroides but no vaejovids. Travelling from Juquila to Oaxaca, they again collected the target vaejovid species and another two species of Vaejovis, one in the mexicanus group and the other in the occidentalis complex. In Oaxaca, they dropped Carlos off before returning to Mexico City via Huajapan de Leon, and on the last leg of the trip collected more interesting scorpions, including a new species related to Vaejovis franckei.
