Between 2009 and 2011, 21 individuals of X. extorris were collected in the area of the Sierra of Jimulco, at Torreón, Coahuila. This finding represents the first record for the state of Coahuila. The potential ecological niche of X. extorris at this mountain was calculated using the software MaxEnt. We also revised the stomach content of 11 individuals. The dietary habits suggest that X. extorris forages near to its preferred microhabitats eating secretive species like spiders, pseudoscorpions and beetles.
