type(s):  Vejovis minimus thompsoni Gertsch & Soleglad, 1972: Female holotype from Anacapa Island, Ventura County, California, April 11, 1968 (M. Thompson), in the American Museum of Natural History.

Original Description:
Gertsch & Soleglad, 1972:

"DIAGNOSIS: Average size about 22 mm., with largest female 27.8 mm. long; color pattern mottled, with black spots on venter of cauda; length of fixed finger exceeding palm length; movable finger about equal to palm length in males, much longer in females; tips of fingers turned inward to form opposable claws; movable finger with seven supernumerary teeth.
...
COLORATION: Base color pale yellowish to dark reddish brown, darkest in adults, with legs and venter of preabdomen paler. Carapace and preabdomen with brown lines and spots more or less completely marking the surface, with usually distinct pale median longitudinal band on preabdomen. Cauda and appendages mottled in brown, with keels dark brown; venter of cauda with series of blackish spots along dark keels.
STRUCTURE: In close agreement with that of minimus minimus except as noted below. For measurements, see table 11.
Carapace: As shown in figure 139. Median eyes 0.22 mm.; median eye tubercle one-sixth of width of carapace at that point. Lateral eyes three; posterior eye small, rarely obsolete.
Pectines: Of female as shown in figure 140. Pectinal tooth counts of female 10, of males 10 or 11.
Cauda: Fourth caudal segment as broad as long; fifth caudal segment about 1.5 as long as broad.
Telson: Vesicle half width of fifth caudal segment.
Pedipalps: Inner keels on fingers flanked by six supernumerary teeth on fixed and seven on movable finger. Tips of fingers curved inward to form conspicuous opposable claws (fig. 138)."
