type(s):  Vejovis minimus Kraepelin 1911 -  Female lectotype (designated by Gertsch & Soleglad, 1972: 600) from San Pedro, Los Angeles County, California, in the Zoologisches Museum, Universitat Hamburg, Hamburg, Germany.

Original Description:

subsequent accounts:
Gertsch & Soleglad, 1972:

"DIAGNOSIS: Average size about 19 mm., with largest female 21.6 mm. long; coloration quite uniform brown; fixed finger of chela about equal to palm width, movable finger somewhat less than palm length; apical teeth on fingers of chela not noticeably enlarged; movable finger with six supernumerary teeth.
COLORATION: Quite uniform medium to dark reddish brown, with keels darker; eye tubercles and tip of sting blackish.
STRUCTURE: Similar in both sexes unless otherwise noted. Measurements as given in table 10.
Carapace: Anterior margin with shallowly rounded emargination in front, with six principal setae, three on each lobe. Carapace coriaceous, covered over most of surface with rounded granules, these less numerous in eye triangle. Median eyes small, about 0.02 mm., separated by almost their diameter; median eye tubercle about one-sixth or one-seventh of carapace width at that point. Lateral eyes three; posterior eye smaller than front pair, in some cases obsolete.
Preabdomen: All tergites granulated, lightly as in front half but with heavier, rounded granules on posterior edges. Tergite VII granulose, with dorsal and submedian keels well developed, set with row of rounded granules. Sternites quite smooth; sternite V with scattered granules on sides.
Cauda: In both sexes (fig. 144) short, thick, not much narrowed behind. First three segments much broader than long; fourth segment few bristles; those on venter in rows of three on most segments.
Telson: Vesicle much narrower than fifth caudal segment, elongate-oval, smooth and flat above, rounded and granulated below, with rows of inconspicuous bristles. Sting moderately curved, about three-fifths as long as vesicle in both sexes. See figure 137.
Pectines: Median piece twice as broad as long, with short, triangular emargination in front, its breadth somewhat more than half of greatest length of pectin. Middle lamellae of females five or six, of males seven or eight. Pectinal teeth offemales nine or 10, of males 10 or 11.
Chelicerae: Dentition typical of genus. Keel on lower margin ofmovable finger smooth.
Pedipalps: Similar in both sexes, with heavy hands resembling those of species of Uroctonus. Femur and tibia of medium size, with keels prominent and provided with rounded granules. Chela robust for size of scorpion, with all keels prominent; superior and outer accessory keels smooth, with a few pits; inner accessory, lateral and all ventral keels granulated, giving inside view crenulate or irregularly serrate lines. Inner keel of fixed and movable fingers with six files of granules flanked by six supernumerary teeth; apical file on movable finger short. Tips on fingers not much curved inward and apical teeth ofmedium development (fig. 136).
Walking legs: Typical for genus, with basal segments finely granulated. Tarsi with ventral line of spinules flanked by fine inconspicuous setae."

distribution: NORTH AMERICA. USA (California: Los Angeles County): Mainland and southern Channel Islands.
