type(s):  Uroctonus lindsayi Gertsch & Soleglad 1972 -  Female holotype from Sierra Laguna, Baja California Sur, México, March 14, 1965 (R. C. Banks), in collection of the California Academy of Sciences (CAS, Type No. 3502).

Original Description:
Gertsch & Soleglad, 1972:

"DIAGNOSIS: Medium-sized, smooth, brown scorpion allied to cazieri, distinguished by following list of characters: total length of larger female 33.2 mm., of male 27.1 mm.; median ocular tubercle situated well in front of middle of carapace; pectinal tooth count of female 12, of male 14; chela stout, smooth, with fixed finger shorter than palm width; lower margins of fixed and movable fingers of chelicera essentially smooth; all keels on cauda prominent, granulated, crenulate to serrulate in lateral view.
COLORATION: Base color tan to quite bright reddish brown. Carapace reddish brown, shiny, with faint dusky, mottled pattern including dusky marginal band. Preabdomen yellowish, with dusky shadings on sides and faint, narrow, median stripe enclosing pair of dusky, subintegumental spots on each tergite. Sternites and pectines pale yellow. Cauda and pedipalps bright reddish brown, with keels dusky red. Telson yellowish brown.
STRUCTURE: Similar in both sexes to those of cazieri unless otherwise indicated. For measurements, see table 6.
Carapace: Of female (fig. 127) smooth over entire surface, with few granules visible even under medium power; of male scattered, inconspicuous granules over most of surface; six weak bristles on frontal margin in both sexes. Frontal emargination a quite wide, rounded indentation. Median ocular tubercle small, smooth, situated about one-third distance from front to posterior margin. Median eyes small, 0.21 mm., separated by full diameter. Lateral eyes, three, well developed; posterior eye smallest, lying above principal pair.
Preabdomen: All tergites smooth in female, lightly granulated along posterior edges; those of male lightly granulated over much of surface and with larger granules on posterior margins. Tergite V of female with weak median and lateral keels bearing about a dozen rounded granules and with few granules in intercarinal spaces; those of male better developed, with more conspicuous granules, and with numerous small granules in intercarinal spaces. All sternites quite smooth; sternite V of female with inconspicuous cluster of pale granules at site of obsolete lateral keel, of male weak keel bearing few pale granules.
Cauda: First and second segments broader than long, posterior ones longer than broad; fifth caudal segment about as long as carapace. All keels prominent, granulated to give crenulated appearance in lateral view; distal granules on dorsal and lateral keels rounded on moderately developed spur; intercarinal spaces mostly smooth, with few scattered granules, most numerous on venter of segment V.
Telson: See figure 128. Vesicle oval, slightly broader than caudal segment V, lightly inflated behind, with weak, rounded granules on sides and below. Sting about half as long as vesicle.
Pectines: Like those of cazieri; number of middle lamellae, eight in females, 10 in males; pectinal teeth, 12 in females, 14 in males.
Chelicerae: With basic pattern of mordax group; keels on lower margins of fixed and movable fingers smooth.
Pedipalps: Like those of cazieri; chela stout, smooth, shining, with weakly developed, smooth dorsal keels, with granules developed on inner, outer, and inferior keels to give denticulate appearance in lateral view.
Walking legs: Like those of cazieri, tarsus with three weak spines on each side flanking middle row of spinules.."

subsequent accounts:
Williams (1980):

"Diagnosis.- Adults to 34 mm long. Base color uniformly tan to reddish brown. Pedipalp with chela swollen; ratio of movable-finger length to carapace length 0.7-0.8; ratio of chela length to width about 2.8-3.0; ventral keel of palm developed and granular; supernumerary granules 7 on movable, 6 on fixed finger. Metasoma with segment III width approximating length, segments I and II wider than long; ventromedian and ventrolateral keels crenular. Pectine teeth 14 in males, 12-13 in females.
Similar to V. rufulus but differs as follows: lack of distinctly developed, angular, granular ventral keel on the pedipalp palm, trichobothrium ip slightly distal to movable finger articulation."

distribution: NORTH AMERICA. México (Baja California Sur - Sierra de la Laguna).

Published Records:  México: Baja California Sur: Sierra Laguna, March 14, 1965 (R. C. Banks), female from under log; May 26, 1965 (Banks, Sloan), male, under rocks and oak litter.

notes: Gertsch and Soleglad (1972) dedicated this species "to Dr. George Lindsay, Director of the California Academy of Sciences, San Francisco, California, who has headed many expeditions into western Mexico and contributed much new knowledge of the plants and animals of Baja California."
