The genus Mastigoproctus (Arachnida, Uropygi, Thelyphonidae), with 14 species, occurs in Cuba, the Antilles, Mexico, southern regions of the United States, and South America (Haupt 2000).
The giant whipscorpion Mastigoproctus giganteus (Lucas 1835) is a common representative of the arachnid fauna of the northern Chihuahuan Desert (Punzo 2001).
Mastigoproctus giganteus, in contrast, may not only lack this ability, but may avoid burrows occupied by small mammals such as grasshopper mice, deer mice and shrews, animals known to include arthropods in their diets (Schmidly 1977; Punzo 2003).
