type(s):  Uroctonus rufulus Gertsch & Soleglad 1972 - Male holotype from Punta Banda, Baja California Norte, México, 200 ft., April 4, 1969 (S. Williams), in collection of California Academy of Sciences (Type No. 11474).

Original Description:
Gertsch & Soleglad, 1972:

"DIAGNOSIS: Medium-sized, brownish scorpion allied to cazieri, distinguished by following features: total length of female 26.9 mm., of male 25.7 mm.; male roughly granulated but female quite smooth; median ocular tubercle well in front of middle of carapace; pectinal teeth, nine for female, 11 for male; chela large in male, well granulated, with fixed finger not so long as palm width; chela of medium size in female, with fixed finger as long as palm width; lower margins of fixed and movable fingers of chelicerae smooth, without trace of denticles; all keels on cauda prominent, granulated, bluntly serrated in side view.
...
COLORATION: Like that of cazieri, yellowish brown, with faint, dusky mottling present on carapace and preabdomen, the latter also with pair of dark, oval spots on each tergite forming median band running into posterior one; keels on cauda and pedipalps reddish brown.
STRUCTURE: Similar to that of cazieri but cauda thinner and pedipalps proportionally smaller. For measurements, see table 5.
Carapace: Of male: entire surface covered with quite heavy, round granules; frontal lobes with six reddish bristles. Frontal emargination a shallow, rounded indentation; median eye tubercle low, with few rounded granules, situated three-eighths distance from front to posterior margin. Median eyes small, 0.2 mm., separated by nearly their diameter. Lateral eyes, three, but posterior eye minute or obsolete. Carapace of female (fig. 129) with inconspicuous granules over most of surface.
Preabdomen: Tergites of male with dull luster, finely granulated throughout, with heavier granules along posterior margins and on each side, most numerous in posterior tergites. Tergite VII with prominent median and lateral pairs of keels, each armed with about a dozen heavy, rounded granules; intercarinal spaces with numerous granules. Sternites quite smooth; sternite V with weak traces of lateral keels. Tergites of female smooth in appearance, seen to be finely granulated under high power, with keels less strongly developed.
Cauda: Of male (fig. 27) with first segment broader than long; second segment as long as broad; posterior segments longer than broad; fifth caudal segment longer than carapace. All keels prominent, with serrate granules; apical granules on dorsal and lateral keels forming distinct, sharp spurs; intercarinal spaces on dorsum of all segments with scattered granules, on venter largely lacking except on segment V. Cauda of female with first three segments broader than long.
Telson: See figure 130. Vesicle elongate oval, slightly narrower than caudal segment V, smooth above, with small granules below and on sides. Sting almost half as long as vesicle.
Pectines: Those of female with median piece twice as wide as long, with very shallow emargination in front; pectin twice as long as median piece; middle lamellae, five; pectinal teeth, nine. Those of male with number of middle lamellae, seven, and pectinal teeth, 11.
Chelicerae: With basic pattern of group; lower margin of movable finger smooth; lower margin of fixed finger without trace of denticles or distinct teeth.
Pedipalps: Of male like those of cazieri but with heavier granulation; chela with superior keel smooth, pitted, flanked by rounded granules; lateral keels more granulose, crenulate in lateral view. Keel of denticles on fixed and movable fingers of chela with six and seven supernumerary teeth respectively. Chela of female smaller.
Walking legs: Like those of cazieri: venter of tarsus with three fine spines on each side of median line of spinules."

subsequent accounts:
Williams (1980):

"Diagnosis.- Adults to 30 mm long. Base color yellowish brown with faint dusky mottling on carapace and mesosomal dorsum. Pedipalp fingers short, palm swollen; ratio of movable-finger length to carapace length about 0.8-0.9; ratio of chela length to palm width 2.8-3.0; palm with ventral keel obsolete; supernumerary granules 6 on fixed finger, 7 on movable finger; fixed finger with trichobothrium id slightly distal to finger origin, trichobothrium ip above movable-finger articulation. Metasoma with segments I and II each wider than long. III with length approximating width, IV with ratio of length to width 1.3-1.4; ventromedian and ventrolateral keels crenular. Pectine teeth 11-12 in males, 9-10 in females.
Similar to V. lindsayi but differs as follows: ventral keel of pedipalp palm distinctly developed, angular, granular (not rounded to obsolescent); trichobothrium ip of fixed pedipalp finger directly over movable-finger articulation (notslightly distal)."

distribution: NORTH AMERICA. México (Baja California Norte - northwestern coastal region from Punta Banda south to Puerto Santo Tomas.).

Published Records:  Mexico: Baja California Norte; 11 mi. E Puerto Santo Tomas, at altitude of 150 ft., July 11, 1969 (S. C. Williams, V. F. Lee), female. Punta Banda, 100 ft., July 10, 1969 (S. C. Williams, V. F. Lee), male, female..

notes: Gertsch and Soleglad (1972) derived the species name "name from Latin rufus, reddish.". Williams (1980) noted that this species appears to prefer hard-packed sedimentary terrain. Most specimens have been collected under dead agave and rocks.
