type(s):  Vejovis reddelli Gertsch & Soleglad 1972 - Female holotype from Pablo's Cave, Uvalde County, Texas, April 5, 1963 (J. Reddell, D. McKenzie), found in first room of cave in darkness about 50 feet from entrance, deposited in the American Museum of Natural History.

Original Description:
Gertsch & Soleglad, 1972:

"DIAGNOSIS: Large, dark scorpion resembling mexicanus and related species of Mexico, readily distinguished by following features: all segments of cauda with ventral keels granulated; first caudal segment slightly broader than long in females, as long as broad in males, succeeding segments usually longer than broad in both sexes; keels on chela rather weakly developed and granulated; keel on lower margin of movable finger of chelicera with several dark teeth; pectinal teeth of females 15-16, of males 18-19.
COLORATION: General appearance in both sexes that of large, reddish to mahogany brown, or blackish scorpion, with tan walking legs and chelicerae. Underside mostly tan, with pectines yellowish. Young specimens paler, with dusky pattern.
STRUCTURE: Dorsal view of male as shown in figure 135. Similar in both sexes, except for smaller size of males. Measurements as given in table 9.
Carapace: Coriaceous, with medium-sized granules in females, concentrated in posterior half and larger ones in males. Area around median eye tubercle and interocular triangle quite smooth in females, rugulose and with heavier granules in males. Frontal margin with rather deep-rounded indentation and set with six long setae; this margin in males revolved to form rugose ridge armed with row of granules. Median eyes about 0.32 mm., separated by more than their diameter, on rather prominent tubercle; eye tubercle about one-fifth width of carapace at that point and situated in front of middle point of length. Lateral eyes (fig. 22) three; posterior eye only slightly smallest.
Preabdomen: Tergites I-II essentially smooth at base, with small granules along posterior edges; tergites III-VI smooth at base but with posterior half or more of each with scattered granules; tergite VII with scattered granules and prominent serrate keels. Stigma of sternite IV of male as shown in figure 12.
Cauda: Dorsal and superior lateral keels sharply serrate, each terminating in sharp, erect spine. Lateral keels serrate on caudal segment I, present and serrate on posterior quarter of segment II, serrate on posterior fifth ofsegment III, and absent on segment IV. Inferior lateral keels serrate on segments I-IV. Inferior median keels unevenly smooth on segment I, weakly serrate on segment II, serrate on segments III-IV. Intercarinal spaces essentially devoid of granulations. Dorsal keels on segment V with uneven patches of weakly serrate granules; lateral keels weak on anterior half, formed by small, pointed granules; inferior lateral keels strongly serrate; single median keel with serrate granules. Ventral setae count of segments I-V, 3-3-3-3-4.
Telson: Vesicle wider than fifth caudal segment in both sexes. Sting about half as long as vesicle, rather abruptly curved at apex, with
inconspicuous nodule and two projecting setae at base.
Median piece about two-thirds as long as wide, with shallow emargination in front.
Median lamellae circular, eight to 12 in both sexes. Pectinal teeth short in females, longer and angular in males; counts of females 15-16, of males 18-19.
Chelicerae: See figures 38, 39. Fixed finger of standard vejovid form with respect to count and position; two or three teeth or nodules present on inconspicuous ventral carina. Movable finger with normal five strong teeth on upper margin; lower margin with heavy distal tooth and keel bearing four or five strong, sharp or rounded, dark teeth. Serrulae present on lower edge of movable finger.
Pedipalps: Similar in both sexes with heavy hands and long fingers. Femur with all keels sharply serrate. Tibia with inner keels serrate, outer keels crenulate, and raised portion on inner face set with two blunt spines. Chela with all keels weakly defined and with no sharply marked ridges. Granulation of superior keel quite smooth, with uneven, rounded granules; inner accessory keel smooth; outer accessory keel barely distinguishable, covered with minute granules; inner keel rounded, with heavy, uneven granules. Inferior keel rounded, with medium-sized granules; inner ventral keel obsolete; inner accessory keel weakly granulated. Six files of fine teeth on inner carinae of fingers, flanked by six supernumerary teeth on fixed and seven on movable finger.
Walking legs: Tarsi with median line of ventral spinules flanked by four or five setae on each side."

subsequent accounts: Sissom and Hendrickson 2005:39,40 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 counts greater than 14 in males, greater than 11 in females; pedipalp chela with ventral face rounded, with or without ventromedian carina; chela movable finger length/ chela palm width ratio greater than 1.8; adults variable in size and color; Cheliceral fixed finger with a carina bearing denticles along the ventral margin; Pectinal tooth counts less than 20 in both sexes; cheliceral movable finger with distinct denticles along ventral margin; adults dark reddish brown in color ................ Pseudouroctonus reddelli

distribution: NORTH AMERICA. USA (Texas). Per Gertsch and Soleglad (1972) , Reddell (1965, p. 167) listed 22 caves in 10 counties where specimens have been taken and classified the species as a "common troglophile in caves throughout the state." Specimens from Texas caves previously referred to Vejovis mexicanus and crassimanus probably are this species. The species also occurs outside of cave habitats as shown by some of the following records.
