holotype from Sierra Laguna, Baja California Sur, México, March 14, 1965 (R.
C. Banks), in collection of the California Academy of Sciences (CAS, Type
Gertsch & Soleglad,
smooth, brown scorpion allied to cazieri, distinguished by
following list of characters: total length of larger female 33.2 mm., of
male 27.1 mm.; median ocular tubercle situated well in front of middle
of carapace; pectinal tooth count of female 12, of male 14; chela stout,
smooth, with fixed finger shorter than palm width; lower margins of
fixed and movable fingers of chelicera essentially smooth; all keels on
cauda prominent, granulated, crenulate to serrulate in lateral view.
COLORATION: Base color tan to quite bright reddish brown. Carapace
reddish brown, shiny, with faint dusky, mottled pattern including dusky
marginal band. Preabdomen yellowish, with dusky shadings on sides and
faint, narrow, median stripe enclosing pair of dusky, subintegumental
spots on each tergite. Sternites and pectines pale yellow. Cauda and
pedipalps bright reddish brown, with keels dusky red. Telson yellowish
STRUCTURE: Similar in both sexes to those of cazieri unless
otherwise indicated. For measurements, see table 6.
Carapace: Of female (fig. 127) smooth over entire surface, with few
granules visible even under medium power; of male scattered,
inconspicuous granules over most of surface; six weak bristles on
frontal margin in both sexes. Frontal emargination a quite wide, rounded
indentation. Median ocular tubercle small, smooth, situated about
one-third distance from front to posterior margin. Median eyes small,
0.21 mm., separated by full diameter. Lateral eyes, three, well
developed; posterior eye smallest, lying above principal pair.
Preabdomen: All tergites smooth in female, lightly granulated along
posterior edges; those of male lightly granulated over much of surface
and with larger granules on posterior margins. Tergite V of female with
weak median and lateral keels bearing about a dozen rounded granules and
with few granules in intercarinal spaces; those of male better
developed, with more conspicuous granules, and with numerous small
granules in intercarinal spaces. All sternites quite smooth; sternite V
of female with inconspicuous cluster of pale granules at site of
obsolete lateral keel, of male weak keel bearing few pale granules.
Cauda: First and second segments broader than long, posterior ones
longer than broad; fifth caudal segment about as long as carapace. All
keels prominent, granulated to give crenulated appearance in lateral
view; distal granules on dorsal and lateral keels rounded on moderately
developed spur; intercarinal spaces mostly smooth, with few scattered
granules, most numerous on venter of segment V.
Telson: See figure 128. Vesicle oval, slightly broader than caudal
segment V, lightly inflated behind, with weak, rounded granules on sides
and below. Sting about half as long as vesicle.
Pectines: Like those of cazieri; number of middle lamellae, eight in
females, 10 in males; pectinal teeth, 12 in females, 14 in males.
Chelicerae: With basic pattern of mordax group; keels on lower margins
of fixed and movable fingers smooth.
Pedipalps: Like those of cazieri; chela stout, smooth, shining, with
weakly developed, smooth dorsal keels, with granules developed on inner,
outer, and inferior keels to give denticulate appearance in lateral
Walking legs: Like those of cazieri, tarsus with three weak spines on
each side flanking middle row of spinules.."
"Diagnosis.- Adults to 34 mm
Base color uniformly tan to reddish brown. Pedipalp with chela swollen;
ratio of movable-finger length to carapace length 0.7-0.8; ratio of chela
length to width about 2.8-3.0; ventral keel of palm developed and granular;
supernumerary granules 7 on movable, 6 on fixed finger. Metasoma with
segment III width approximating length, segments I and II wider than long;
ventromedian and ventrolateral keels crenular. Pectine teeth 14 in males,
12-13 in females.
Similar to V. rufulus but differs as follows: lack of distinctly developed, angular, granular ventral keel on the pedipalp palm, trichobothrium
ip slightly distal to movable finger articulation."

Gertsch and Soleglad (1972) dedicated
this species "to Dr. George Lindsay, Director of the California Academy
of Sciences, San Francisco, California, who has headed many expeditions into
western Mexico and contributed much new knowledge of the plants and animals
of Baja California."
