type(s):  Vejovis iviei Gertsch & Soleglad 1972 -  Female holotype from San Juan, Nevada County, California: September 15, 1963 (Jean and Wilton Ivie), in the collection of the American Museum of Natural History..

Original Description:
Gertsch & Soleglad, 1972:

"DIAGNOSIS: Small, brown, granulated scorpion with appearance of Uroctonus group but presenting several important differences: average size of males about 25 mm., of females about 30 mm., median eye tubercle situated well in front of middle of carapace; pectinal tooth count for females 10, for males 11; lower margin ofmovable finger ofchelicera essentially smooth; inferior lateral and median keels on basal segments of cauda prominent and granulated; chela with inner ventral keel well developed.
COLORATION: Base color dark reddish brown, with legs, chelicerae, and underside of preabdomen dusky to yellowish. Carapace and preabdomen with more or less distinct, reticulate pattern of lines and spots; preabdomen with narrow central longitudinal yellowish band, bordered by dusky stripe of granulation, from base to cauda, visible in some specimens.
STRUCTURE: Similar to that of reddelli in basic features unless otherwise indicated. Descriptive data and measurements (table 9) based largely on specimens from Shasta County. Structure similar in both sexes except as noted.
Carapace: Finely granulated over most of surface, less so in interocular triangle, with largest granules on side wings flanking median ocular tubercle; frontal margin with six principal setae of medium length. Frontal emargination small, rounded indentation. Ocular tubercle of average size, situated back of front about three-eighths of distance to posterior margin. Median eyes small, 0.22 in female, separated by less than full diameter. Lateral eyes (fig. 21) three; posterior eye smallest, set back and above the contiguous pair.
Preabdomen: Tergites densely and finely granulose, more so in males; dorsal keels readily discernible on all tergites of males, on posterior ones forming weak granular crests; these keels barely visible in females, segment VII with well-developed, granular median and lateral crests, each with about 15 small granules, and with numerous small granules in intercarinal spaces. Shape of stigma IV of female as shown in figure 13.
Cauda: First and second caudal segments wider than long; third segment about as broad as long. All keels prominent and granulated; last granule in files on dorsal keels produced into small projection; single median keel on segment V undivided at apex; intercarinal spaces without conspicuous granulation.
Telson: See figure 150. Vesicle narrower than caudal segment V, elongate oval, smooth above, with dorsal and lateral crenulations or weak granules; sting half as long as vesicle.
Pectines: Median piece with deep, shallow, V-shaped emargination in front; middle lamellae, six or seven in both sexes; pectinal teeth, nine or 10 in females, 11 in males; outer pectinal teeth enlarged.
Chelicerae: Keel on lower margin of movable finger essentially smooth, with few weak crenulations.
Pedipalps: All keels on femur and pedipalp with rounded granules. Frontal spurs weak, rounded projections bearing single enlarged granule on each side. Chela rather small with carina moderately well developed and intercarinal spaces smooth; superior carina and accessory carinae mostly smooth; outer keel lightly crenulated; inferior carina essentially smooth; inner ventral carina well developed, lightly granulated.
Walking legs: Single row of spinules on venter of tarsus flanked by three bristles on each side."
