Type.-Paruroctonus hirsutipes: Holotype female (adult) from U.S.A., California,

Imperial County, 14 miles W Winterhaven, 25 July 1967 (M. A. Cazier). Depository:

CAS, Type No. 15060.

Diagnosis.-A species in the borregoensis group of subgenus Pan4roctonus differentiated

by any one of the following: telotarsi I-III with 4, 5,5-6 (usually six on III) retrosuperior

setae (Fig. 16); basitarsus III with nine to 10 superior setae (Figs. 30-31); basitarsi

I-III strongly compresselda terally, superior setae on each segmenti n single fde (Figs.

28-31); humeral macrosetae inconspicuous or absent on internal surface, three on dorsal

surface (proximal absent); chelal internal setae absent; chela with four (of 26) triehobothrla

on ventral palm (Figs. 23-24); dorsal metasomal setae I-IV inconspicuous in both

sexes, 0,1,1,1 pairs: pectinal teeth in males 26-27.

ComparisonsT: able 2. Differs further from P. borregoensisi n having one retroinferior

terminal seta on telotarsus I.

Description of female holotype (adult male unknown).-Measurements: Table

Coloration: pale yellow with very weak fuseous markings on carapace and tergites.

Carapace: anterior margin very subtly concave; surface very finely granular; furrows and

carinae weakly developed except posterior median furrow moderately developed postedorly.

Tergites: I-VI uniformly extremely freely granular, posterior margins with very weak

granules; VII finely granular; median carina I-IV obsolete, V-VI barely discernible, VII

smooth, weak; VII paired lateral carinae weakly developed, weakly granular. Sternites:

III-VI smooth to very freely granular; VII lightly granular, one pair moderately developed

granular lateral earinae. Metasomacl arinae: dorsals I-IV weak, crenulate, dorsal furrow

I-III shallow, IV very shallow; dorsolaterals I-IV very weakly granular, V obsolete,

smooth; laterals I weakly granular, II-IV obsolete, V marked by few weak granules

anteriorly; ventrolaterals I-III weak, smooth, IV weakly granular, V granular to dentate;

ventrals I obsolete, II-III weak, smooth, IV weakly granular, V dentate; intercarinal

surfaces very finely granular except V sparsely granular ventrally. Metasomasle tae: short

to moderately long, very fine; dorsals 0,1,1,1; dorsolaterals inconspicuous or absent;

laterals 0,0,0,0,2-3 ; ventrolaterals 2,3,3,4,10; ventrals 2.3,4,4. Telson: smooth; eight pairs

long lateral and ventral setae. Pectines: do not quite reach distal margin of coxa IV.

Chelieera: fixed digit with one or two pigmented dentieles on inferior border; movable

digit with four or five crenulations on inferior border. Humerus: all earinae moderately

developed, lightly to moderately granular; intercarinal surfaces very finely granular;

macrosetae include three dorsals, proximal absent, and two external medials; internal

surface without macrosetae. Brachium: internal carinae weakly granular, extemal carinae

obsolete to smooth; intercadnal surfaces smooth; four internal macrosetae, dim short and

t’me. Chela: all carinae weak, smooth, except ventroexternal and ventral lightly granular

proximally; intercarinal surfaces smooth; internal macrosetae inconspicuous or absent;

primary denticles on fixed fingers 3,4,5-6,5,5-4,6-5, movable fingers 6-5,6,6,6-7,6-4,3-4.

Basitarsi I-III: strongly compressedla terally; mrs seta on III short, free, set well away

from superior setae; superior setae 6-5,8,10. Telotarsal setae I-IV: proinferiors 1,1,1,1,

distal inconspicuous or absent on each segment;promedials 2,2,2,1 ;prosupedors 3,3,3,3,

proximal distinctly smallest on each; retrosuperiors 4,5,5-6,4, proximal reduced on IV;

retromedials 1,2,2,2; retroinfefiors 0,1,2,2, distal inconspicuous or absent on each segment

III-IV; retroinferior terminals 1,2,2,2, most superior of two inconspicuous or very

fme.UngueIs4 V: about 3/4 as long as, or samel ength as, telotarsus.

Variation.-Weak fuscous markings more evident in immatures. Ventral metasomal

setae varied 2,3,3-4,4; laterals on V varied from 0 to 3. Pectines in juvenile male extend to

1/2 length of trochanter IV. Primary dentides in rows 1-5 total on pedipalp fixed finger

22, movable finger 27-32.

Etymology.-The name "hirsutipes" refers to the relatively numerous tarsal setae

characterizing this species.

Remarks.-This species and P. xanthus represent the most conspicuously modified

arenicolous species in the genus Paruroctonus.B oth species appear to be restricted to the

extensive sand dunes at the northern end of the Gulf of California.

Distribution.-Fig. 27. Extreme southeastern California and adjacent Yuma County,
