type(s) :  Vejovis (Paruroctonus) luteolus Gertsch & Soleglad, holotype (adult female): AMNH, 2 miles (3.2 km) E Anza-Borrego State Park on Highway 78, San Diego County, California, USA, 22-IV-1960, (W. J. Gertsch)..

original description:
Gertsch and Soleglad 1966:

"DIAGNOSIS: Very distinct species (fig. 63), probably smallest of group, with females not exceeding 30 mm. in length. Pedipalps having small hands with short fingers and carinae quite smooth in females. Pectinal tooth count quite low, 11-14 in females and about 17 in males.
COLORATION: Entire body yellow to bright orange-brown, except for black eyes and tubercles and red tip of sting; black color of eye tubercles usually forming transverse bar between eyes (fig. 68).
STRUCTURE: Similar to that of boreus and relatives in both sexes except as noted below. Males considerably smaller than females in available material. Measurements given in table 4.
Carapace: Shape of carapace of female from 2 miles east of Anza-Borrego State Park, California, as shown in figure 68. Carapace essentially straight, at most with gentle forward curvature, with six short bristles on margin; sides straight to broadly rounded at posterior corners; length and breadth behind subequal. Median eyes set on low, smooth tubercles; width of median diad one-fourth of width of carapace at that point. Carapace of female smooth and shining, without conspicuous granules visible under low power; of male, dull, rough, with quite heavy granules on elevated areas.
Preabdomen: Tergites quite smooth and shining in female, with weak granulation; duller and rougher in male, with numerous weak granules.
Cauda: Dorsal and superior lateral keels of female not prominent, clear and smooth, with edges slightly and somewhat irregularly serrulate. Inferior lateral keels largely obsolete on segments I and II, visible and weakly crenulate in posterior third of segment III, more distinct and with weak granules in posterior half of segment IV. Inferior median keels obsolete on basal segments, faintly visible and weakly crenulate on segment IV. Segments I-IV with 3-4-4-5 pairs of setae on obsolete, inferior, median keels. Segment V only slightly longer than carapace; dorsum unevenly covered with round granules; intercarinal spaces on ventral surface covered with granules. Keels of males more prominent and with heavier granules.
Telson: In both sexes slender, with slightly curved sting half as long as granulated vesicle.
Pectines: Those of female as shown in figure 69, rather small, only twice as long as wide median piece; middle lamellae inconspicuous, consisting of about 12 or 13 round pieces; pectinal teeth short, 11-15 in number. Those of male much larger and broader; median piece about as long as broad; middle lamellae consisting of 13-15 round pieces; pectinal teeth twice as long as those of female, distinctly angled at middle, 16-19 in number.
Genital operculum: Of female as shown in figure 69.
Chelicerae: Similar in both sexes (figs. 52-54), quite similar to those of boreus. Lower margin of fixed finger weakly developed, with traces of two weak nodules. Movable finger with five strong teeth, on upper margin of which distal tooth is well developed; lower margin with very stout distal tooth and keel lightly crenulated.
Pedipalps: Those of female of medium length, with chelae short with short fingers (fig. 30). Carinae on basal segment rounded, weakly granulated. Chela with all eight carinae visible, mostly quite smooth, with light granulation at angles. Those of male with proportions of those of female, but carinae more developed and quite heavily granulated. Inner keels of fingers essentially straight, dentate as in boreus.
Walking legs: Protarsi of second and third legs with six to eight long setae."

subsequent accounts:
Williams (1980):

"Diagnosis. Adults to 30 mm long. Entire body light yellow to orange-brown, no contrasting dark color patterns; females with terga and carapace smooth and lustrous, males somewhat more granular and less lustrous. Metasoma with dorsal and dorsolateral keels not prominent, these smooth; ventrolateral keels more or less obsolete on segments I and II, visible and weakly crenulate on posterior of segment III, more distinct and with weak granules on posterior region of segment IV;metasoma with ventromedian keels of segments I-III obsolete, on segment IV faintly visible and weakly crenulate; pectine teeth 11-15 in females, 16-19 in males; chelicera with ventral margin of movable finger lightly crenulated, ventral margin of fixed finger with traces of two weak nodules."

Haradon, 1984b:

"Diagnosis. - A species in the borregoensis group of subgenus Paruroctonus differentiated by: telotarsus III with two retrosuperior setae (Fig. 13); basitarsus III with six (4 + 2); superior setae (Figs. 44-45), moderately large extraneous setae often present; brachium with five internal macrosetae, including msm (Fig. 3); telotarsus I with one retroinferior terminal setae.
Comparisons: Table 2. Differs further from P. borregoensis and P. ba/ae in having more deeply scalloped pedipalp fingers in adult male (Fig. 21).  Differs further from P. borregoensis in having four external medial macrosetae on distal 3/5 of humerus (Fig. 4); long dorsal and dorsolateral metasomal setae I-IV in both sexes; four internal macrosetae on pedipalp palm, two on fixed finger, in both sexes. Differs further from P. bajae in having granular ventrolateral and ventral metasomal carinae I-IV in male.
Variation.-Two relatively distinct populations are characterized as follows:
Population I. Distribution: Colorado Desert, primarily northwest and west of the Salton Sea. Description: adult carapace length in adult males 3.0-5.0 mm (4.23 ± 0.38 mm, n = 56), females 4.0-6.6 mm (4.42 + 0.33 mm, n = 77); carapace length/pedipalppalm width ratio in adult males 1.6-1.8 (1.77 + 0.05, n = 55), females 2.2-2.7 (2.49 + 0.11, n = 81); pectinal teeth in males 16-22 (18.83 + 1.30, n -- 162), females 10-16 (13.17 + 1.05, n = 228), 81.6% of females with 13 or more.
Population II. Distribution: Mojave Desert and southern Nevada. Description: adult carapace length in males 2.8-3.8 mm (3.20 + 0.18 mm, n = 49), females 3.2-4.8 mm (3 .52 + 0.31 mm, n = 29); carapace length/pedipalp palm width ratio in adult males 1.9-2.3 (2.04 + 0.11, n = 50), females 2.5-2.9 (2.71 -+ 0.14, n = 30); pectinal teeth in males 16-19 (17.46 + 0.96, n = I08), females 10-13 (11.60 + 0.76, n = 86), 88.4% of females with 12 or fewer."

notes:   Williams (1980) considered Paruroctonus bajae Williams 1972 to be a junior synonym  of this species.

Haradon, 1984b:

More than in other species of the borregoensis group, P. luteolus often has one to three moderately large extraneous setae on the superior surface of the basitarsi. The most common of such setae occurs along the prosuperior border just proximal to but offset from the distal row in the diagnostic series. In all the specimens that were studied, however, the basic pattern of 4 + 2 superior setae on basitarsi II and III remained detectable.
