* Transfered to Hoffmannius by Soleglad & fet, 2008.Official US common name is "Arizona Stripedtail Scorpion".
"The Arizona Devil Scorpion" has also been used. The latin name spinigerus means "spine bearing"
and does not refer to the stinger, rather the enlarged, spinelike processes at the distal ends of
the dorsal keels on tail (metasoma) segments I--IV. This is one of the earliest Vaejovis species
described (1863), and this character is now known to be common throughout the genus, however not
nearly as pronounced as in this species.
North America (Mexico and USA (Arizona, California, &
New Mexico). The type specimen was reported from "Texas", but has not been found in
Texas since the original description!
An inhabitant of the Sonoran Desert and associated grasslands, pine-juniper
forests, and chaparral. Barely enters California from the east and New
Mexico from the west (basically along the borders of Arizona with both
states) and northwestern Sonora, from Guaymas northward. Found in almost
every situation within its range except dunes, rare in excessively sandy soils. Although it is a burrower, it is very commonly found under rocks
and surface objects, under which it digs out "scrapes".
Update: This species is more widely distributed in New Mexico than described above: It has been found in the Albuquerque area in the center of the state and it is also found in colony situations and populations appear to be disjunct (Thanks to A. Dale Belcher for this information!).
