DIAGNOSIS: Small, golden brown, densely granulose
scorpion with basic features of genus but distinctive in following
characters: one of our smallest species, with length variation in adults
from about 15 mm. to 22 mm., females larger; median eye tubercle far in
front of middle of carapace; pectinal tooth count of females seven to
nine, of males eight to 10; lower margin of movable finger of chelicerae
smooth; inferior lateral and median keels of caudal segments I-IL
granulated; caudal segment IV distinctively longer than wide.
COLORATION: Base color golden-orange to dusky orange-brown with faint
traces of darker pattern present on carapace and preabdomen in some
specimens, mostly with few contrasting markings; eye tubercles and tip
of sting black; pedipalp and cauda with some dusky shadings. Legs
yellow. STRUCTURE: Features like those of mordax unless otherwise
indicated. Males smaller than females, similar to females except as
noted. For measurements, see table 7.
Carapace: Most of surface, with dense covering of rounded granules;
interocular area of female with sparse granulation; frontal margin with
six long setae. Frontal emargination a shallow indentation. Ocular
tubercle far in front of middle of carapace, situated about one-third
distance from front to posterior margin. Median eyes small, about 0.15
mm., separated by full diameter. Lateral eyes three or two; posterior
eye small, often missing.
Preabdomen: All tergites finely to quite coarsely granulated, more so in
males, posterior ones with heavier granules; tergite VII with
well-developed dorsal and superior lateral keels, provided with numerous
pointed granules, and with numerous rounded granules in intercarinal
Cauda: Segments I-III broader than long; segment IV distinctly longer
than broad; segment V twice as long as broad. All keels on cauda
prominent and distinctly granulated. Placement of ventral setae on basal
Telson: Vesicle covered below and on sides with large, rounded granules,
smooth above, slightly inflated on sides. Sting short, curved, about
one-third as long as vesicle.
Pectines: Like those of mordax in basic features. Median piece about
twice as broad as long, with shallow indentation on front margin. Middle
lamellae, five or six. Pectinal teeth, seven to nine in females, nine or
10 in males; outer tooth slightly larger.
Chelicera: With standard dentition of genus. Lower margin ofmovable
Pedipalps: Chela of medium stoutness, with short fingers; fixed finger
shorter than width of palm. Keels of femur and tibia well granulated;
fine granulation in intercarinal spaces; frontal spurs on tibia small.
Superior keel smooth but ventral keels roughened, with irregular rows of
granules. Keels on movable and fixed fingers flanked by six
Walking legs: With few thin setae and shorter spines; line of spinules
on venter of tarsus with two or three setae on each side.
to 22 mm long. Base color of cuticle uniform golden-brown. Cuticle densely granulose.
Pectine teeth 7-9 in females, males 8-10. Metasoma with ventromedian and ventrolateral
keels crenular; metasomal segment III as long as or slightly longer than wide. Pedipalp
movable finger with 6 supernumerary granules;
pedipalp with palm greatly swollen; ratio of movable finger length to palm
width 1.8 or less. Pedipalp fixed finger with trichobothria id and ip on
finger origin directly above movable finger articulation.
Similar to V. rufulus and V. lindsayi from which it is
distinguished by 6 supernumerary granules on pedipalp movable finger (not
