Mastigoproctus - Mastigoproctus tohono

Mastigoproctus - Mastigoproctus tohono
Chiricahua National Monument, Cochise County, Arizona, USA
September 25, 2021
Size: ~50 mm TL
Found in the restroom at Bonita Canyon Campground. Measurement was from front of face to end of abdomen. Except for possibly range, I cannot see a way to differentiate between giganteus and tohono.

giganteus no longer exists.
Giganteus was revised and no longer ranges into AZ.

M. tohono is the Arizona species
M. giganteus is texas
M. floridanus in florida
