holotype from the Southwestern
Research Station grounds, 5400 ft., 5 mi. SW Portal, Cochise County,
Arizona, July 1, 1967 (V. Roth), in the collection of the American Museum of
Gertsch & Soleglad,
"DIAGNOSIS: Smaller, more slender,
more granulated scorpion than huachuca, readily distinguished by
following features: average length about 25 mm., with some females
attaining 35 mm.; median eye tubercle placed well in front of middle of
carapace; frontal emargination on carapace less deep than that of
huachuca; pectinal tooth count averaging 10 for females, 11 for males;
lower margin of movable finger of chelicera essentially smooth; chela
smaller than that of huachuca, with hand less inflated.
COLORATION: Similar to that of huachuca, quite uniform tan to dark
reddish brown, with all carinae darker.
STRUCTURE: Similar to huachuca in basic features unless otherwise
indicated. Descriptive data and measurements (table 2) based largely on
specimens from Portal, Cochise County, Arizona. Structure similar in
both sexes except as noted.
Carapace: In both sexes densely provided with medium-sized granules;
frontal margin with six short setae. Frontal emargination shallowly
rounded. Ocular tubercle far in advance of middle of carapace. Median
eyes small, 0.19 mm., separated by full diameter. Lateral eyes typically
three in number; posterior eye smallest, often missing.
Preabdomen: All segments liberally provided with medium-sized granules,
most numerous in males; tergite VII with prominent keels, each one with
about 15 large, rounded granules, and intercarinal spaces with numerous
Cauda: First and second caudal segments of both sexes distinctly broader
than long; third segment about as broad as long. All keels prominent,
distinctly granulated to give serrated appearance in lateral view, with
distal granule in each series raised on sharp point; single inferior
median keel of segment V distinct to apex; intercarinal spaces on
segment V with many heavy granules above and on sides.
Telson: Similar to that of huachuca: vesicle somewhat narrower than
fifth caudal segment, smooth
above, lightly granulated below and around sides, especially near base;
sting about half as long as vesicle.
Pectines: Like those of huachuca but with more elements. Middle
lamellae, six in females, seven in males; pectinal teeth, nine or 10 in
females, 10 or 11 in males; outer tooth larger than others.
Chelicerae: Keel on lower margin of movable finger essentially smooth,
in few cases slightly crenulated, but without development of
Pedipalps: Chela of medium stoutness, with movable finger somewhat
shorter than palm; palm narrower, not inflated on inner side. Superior
carina prominent, crenulate to lightly granulated; all other carinae
granulated. Inner flanking teeth of fixed finger, six, of movable
Walking legs: With basic spination of huachuca, with relatively short
spines; single row of spinules on venter oftarsus not flanked by short

Key to the Vaejovid Scorpion Species of Northeastern México - Dorsolateral
carinae of metasoma (at least on segments I–III) with an enlarged terminal
denticle; legs I–III with irregular setation (except in V. globosus,
which has setal combs, – but has the enlarged terminal denticle on the
metasoma) Trichobothria ib and it situated at base of chela
fixed finger; Pectinal tooth 9–13 in males, 8–11 in females; pedipalp chela
with ventral face flattened and without ventromedian carina; adults are
small reddish brown scorpions..... Pseudouroctonus apacheanus*
