type(s):  Holotype male (adult) from U.S.A., California, San Diego County, 13 miles (21 km) NE Borrego Springs (500 ft.), 7 October 1967 (M. A. Cazier et al.). Depository: CAS, Type No. 11336.


Subsequent accounts:
Williams (1980):

"Diagnosis.- Adults to 35 mm long; body entirely pale whitish yellow, without contrasting dark or dusky markings. Ventrolateral keels of metasomal segments I-IV crenular, ventromedian keels obsolete on segment I, lightly crenular on segments II and III; male pedipalps with short fingers, palms greatly swollen; pectine teeth 15-18 in males, 11 in females; space between ventromedian keels of metasoma lacking abundant, stout, reddish setae, segment III with fewer than 10 setae; pedipalp fixed finger distinctly shorter than palm.
Similar to P. luteolus but differs as follows: metasoma with dorsal keels not as strongly developed and not as crenulate in females; males with more granular pedipalp chela: ratio of pedipalp chela length to palm width usually 1.45 or less in adult males; male metasomal setae greatly reduced and inconspicuous."

Haradon (1984a):

"Diagnosis. - A species in the borregoensis group of subgenus Paruroctonus differentiated by combination of: telotarsus III with three retrosuperior setae (Fig. 14); basitarsus III with seven (5 + 2) superior setae (Figs. 7-8); dorsal and dorsolateral metasomal setae I-IV inconspicuous in adult male, brachium with dsm and dim internal setae (Fig. 1) and  chelal internal setae inconspicuous in adult male.
Comparisons. - Table 2. Differs further from P. ammonastes in having always 14 trichobothria on external surface of brachium. Differs further from P. bajae in having less developed inferior denticles on cheliceral fixed digit; two external medial macrosetae on distal 3/5 of humerus (Fig. 2), primarily granular ventral and ventrolateral metasomal carinae I-IV in male. Differs further from P. luteolus in having two retroinferior terminal setae on telotarsus I; two external medial macrosetae on distal 3/5 of humerus; lacking msm internal macroseta on brachium."

distribution: NORTH AMERICA. México (Baja California Norte, Sonora), USA (southwestern Arizona, southeastern California). Colorado Desert region. View Map

published records:  Paratypes: 22M, 8F (CAS; including allotype female), 21 km NE Borrego Springs, San Diego County, California. 7-X-1967, M. A. Cazier.  Arizona: Yuma Co., San Luis. 22-VII-1967 (Cazier). Baja California Norte, Mexico: N end Laguna Salada. 3 1-III-1969 (Williams). Sonora, Mexico: 8.0 km N El Golfo. 5-VI-1968 (Cazier); 10.? km N Puerto Peiiasco. 3-VI-1968 (Cazier).

notes:  Beutelspacher (2000) was unaware that the records of P. luteolus from San Felipe and Persebu, Baja California (Norte) were referable to P. borregoensis.  Haradon (1984) recognized two subspecies. distinguished by different numbers of pectinal teeth in both sexes.
