Mexico (Guerrero) 2009

23–26 July, 2009:Grant collaborator Oscar F. Francke and five students (IBUNAM undergraduates Tania Lopez Palafox and Cinthia Quijano, and IBUNAM graduates Hector Montaño, Carlos Santibañez and Alejandro Valdez) traveled to the state of Guerrero. Specifically targeted was Omiltemi, in the mountains west of the state capital, Chilpancingo, because it is the type locality of several important arachnid species described at the turn off the last century in the Biologia Centrali-Americana, among them a pholcid spider, Ixchela simonis Pickard-Cambridge described only from females; the team obtained a series including the first known adult males as well as material suitable for DNA extraction.  Omiltemi is the type locality forVaejovis pusillus Pocock, a poorly understood taxon which had been reported from numerous other mountainous locations; topotypes and fresh material for DNA analyses will enable this taxonomic complex to be deciphered.

 29–30 July, 2009: Grant collaborator Oscar F. Francke, along with IBUNAM undergraduate student Tania Lopez Palafox and IBUNAM graduate students, Carlos Santibañez and Alejandro Valdez, returned to the vicinity of Mezcala, Guerrero, where Tania is surveying the arachnid biodiversity for her B.S. thesis. A single specimen of a new species of Vaejovis was collected nearby, but rains prevented further collections.
