Araneomorphae of Las Pozas Xilitla

Dr. Fernando Alvarez Padilla


Las Pozas spider inventory morphospecies pages include 2,233 images for 207 morphospecies of Araneomorphae spiders. Approximately 4,100 adult spiders were captured in four expeditions from 2011 to 2012. Locality data: Mexico: San Luis Potosi, Xilitla, Xilitla City Las Pozas 21°23'50" N, 98°59'38" W. 662 m. 2011-2012. Leg. Lab. Aracnologia FC-UNAM.

All specimens were collected inside one hectare plot of a 25-35 year old remnant tropical forest. This remnant is inside an ecoturistic and artistic development known as Las Pozas near The City of Xilitla. Sampling protocols followed (Coddington et al 1991, 1996, 2009; Scharff et al 2003; Sörensen et al. 2002). For more information about these methods and sampling protocol go to the references at the Biodiversity main page.
