Original description:
Uroctonus huachuca
Gertsch & Soleglad (1972):

"DIAGNOSIS: Smaller, more slender scorpion resembling mordax in general appearance but differing in following features: average size about 30 mm., some female specimens 40 mm. long; median eye tubercle placed well in front of middle of carapace; pectinal tooth count averaging eight for females and nine for males; fingers of chela stouter and proportionally shorter in comparison with palm; lower margin of movable finger of chelicera crenulate, with a few pale teeth but lacking dark ones; inferior lateral and median keels of basal segments of cauda granulated.
COLORATION: Base color in
most cases paler than that of mordax, varying from tan to dark reddish brown. Mature specimens with carinae of pedipalps and cauda darkly pigmented in contrast to lighter body color. Legs and telson light yellow. Juveniles entirely pale yellow until subadult stages.
STRUCTURE: Similar to that of mordax in basic features unless otherwise indicated. Descriptive data and measurements (see table 2) based largely on specimens from Carr Canyon, Huachuca Mountains, Arizona. Structure similar in both sexes unless otherwise noted.
Carapace: Finely granulated over most of surface; ocular triangle mostly devoid of heavy granulation; lateral wings with somewhat heavier granulation; frontal margin with six short setae. Frontal emargination well rounded. Ocular tubercle far in advance of middle of carapace. Median eyes small, 0.22 mm., separated by about their diameter. Lateral eyes three; posterior eye smallest, in many cases missing.
Preabdomen: Basal tergites relatively smooth, very finely granulated; apical ones with more larger granules; tergite VII with well-developed pair of keels on each side, each keel provided with about 10 large, rounded granules, and intercarinal spaces with small, inconspicuous granules.
Cauda: First caudal segment of female distinctly broader than long; second segment about as broad as long. First caudal segment of male about as broad as long; second segment longer than broad. All keels prominent and distinctly granulated to give serrated appearance in lateral view; single inferior median keel of segment V not at all or only weakly bifid at apex; intercarinal spaces of segment V lacking heavy granules.
Telson: Similar to that of mordax; vesicle about as wide
as caudal segment V; sting about half as long as vesicle.
Pectines: Like those of mordax but with fewer elements. Middle lamellae, five in both sexes; pectinal teeth, eight in females, nine (or rarely eight) in males; outer pectinal tooth distinctly larger than others.
Chelicerae: Like those of mordax except as follows: keel on lower margin of movable finger smooth, lightly crenulated, or with few pale nodules; with row of delicate serrulae on lower edge of tip ofmovable finger.
Pedipalps: All keels on femur and tibia granulated. Frontal spurs on tibia prominent with one granule per spur, but not so sharp as those of mordax. Chela (fig. 117) stout, with movable finger as long as palm; superior keel prominent, quite smooth; granulation and position of keels like those of mordax. Six inner flanking teeth on fixed and movable fingers (figs. 116, 118). For trichobothrial pattern see figures 64-67.
Walking legs: With basic spination of mordax but setae fewer and stouter; single row of spines on venter of tarsus with row of evenly spaced, short setae on each side."

subsequent accounts: Williams and Savary (1991) reported that this species is related to U. giulianii in structure and coloration, but differs as follows: metasoma with dorsal keel macrosetal formula 0-0-0-0 or 0-0-0-1 (not 0-0-1-1 or 0-1-1-1) on segments I-IV; acu1eus longer, ratio of vesicle length to aculeus length less than 1.9 (x = 1.7 ± 0.1, n = 8).

distribution: NORTH AMERICA. USA (Arizona: Santa Rita & Huachuca Mountains, from 1600 to 2440 m elevation).

notes: Gertsch & Soleglad, (1972) named this species after the Huachuca Mountains of Arizona. Williams and Savary (1991) Williams and Savary (1991) noted that Uroctonites huachuca is found in limestone cave and surface environments, but no evidence of unique cave adaptations is apparent. They further noted that observations by Bill Peachey, an Arizona speleologist, suggest a permanent population inhabits Hidden Cave in Santa Cruz County, Arizona. The Hidden Cave populaton is the first cave record for this species.
