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."

of northern California.
