Distribution. Mexico (north, Baja California), USA

(southwest).

The range of this genus forms three primary disjunct parts in addition to three other isolated ranges based on solitary species (see map in Fig. 206 ). The most northern species, P. iviei , is distributed throughout northern California, with P. glimmei occurring just south in Monterey and Mendocino Counties. Several Pseudouroctonus species occur in southern California ( P. angelenus , P. bogerti , P. williamsi , and P. minimus ), or in southern California and northern Baja California, Mexico ( P. andreas and P. rufulus ). The third major part of the disjunct range of Pseudouroctonus includes southern Arizona, New Mexico, Texas, and extreme northern edges of Sonora, Chihuahua, and Coahuila, Mexico ( P. apacheanus , P. reddelli , and P. sprousei ). Separate, disjunct ranges are exhibited by species P. cazieri (southern Baja California), P. lindsayi (extreme southern Baja California Sur), and P. chicano (southern Chihuahua, Mexico).

Taxonomic history. The genus was established by Stahnke (1974), initially with only one species. Stockwell (1992) transferred here the species formerly placed in the “minimus ” group of the overly inflated Vaejovis . Beutelspacher (2000), without any reasoning, synonymized Pseudouroctonus back to Vaejovis .
