Paruroctonus surensis Williams &
Haradon: Holotype male (adult) from
México, Baja California Sur, 12 km SE Guerrero Negro, 18 August 1974 (R. M. Haradon,
V. F. Lee, W. E. Savary). Depository: CAS (Type No. 12249).
Williams and Haradon in Williams (1980):
"Diagnosis. Pale yellow base color with
pigmented interocular space on carapace. Pectine teeth 17-19 in males, 8-9
in females. Pedipalp fingers short, fixed finger shorter than palm, with 6
and 7 interior supernumerary granules on fixed and movable fingers,
respectively. Similar to P. borregoensis and P. pseudopumilis.
Differs from P. borregoensis as follows: denticles absent (not with 1
or 2) on ventral margin of fixed cheliceral finger; interocular dusky
pigmentation on carapace; proximal digital scalloping on chela of male
reduced (does not form distinct gap when closed); chela less stout, ratio of
palm length to width greater than 1.50 (not 1.45 or less). Differs from P. pseudopumilis as follows: 7 (not 6) interior supernumerary granules
on movable pedipalp finger; attains slightly larger adult size; metasomal
setae on males greatly reduced (not long and conspicuous).
Description of Holotype. Male. Extensive light dusky markings in interocular
area of carapace; pedipalp fingers orange-yellow, darker than palms; cuticle
otherwise pale yellow. Carapace surface moderately granular; anterior margin
essentially straight, protrudes slightly medially. Terga lightly granular,
mainly posteriorly on each tergum. Ventrolateral metasomal keels I=III
crenulate posteriorly, IV crenulate entirely, V serrate; ventromedian keels
I=III weakly developed and smooth, IV posteriorly crenulate, V crenulate to
serrate; setae short, fine, inconspicuous; ventromedian setae 3, 3, 4,5
pairs on segments I-IV. respectively. Telson elongate, moderately tubercular
on ventral and ventrolateral surfaces; slight subaculear tubercule. Surface
of pedipalp chela very finely granular, dorsal and marginal keels moderately
developed and lightly granular; fingers weakly scalloped proximally, form
very slight space when chela closed; 6 supernumerary granules on fixed
fingers and 7 on movable fingers.
Description of Allotype.—Female. Similar to holotype but differs as follows:
carapace, terga, and pedipalps smooth and glossy. Metasomal setae long and
conspicuous; ventrolateral keels I-III smooth, ventromedian keels I obsolete
to smooth, II—III smooth, IV crenulate posteriorly. Telson surface smooth.
Pedipalp-palm keels obsolete to weakly developed, smooth to lightly
granular; dentate margins of fingers essentially even, unscalloped.
Variation within Paratypes.—Similar to holotype and allotype except as follows: ventral counts of metasomal setae in segments I—IV more commonly 3, 4, 4, 5. Pectine teeth 17-19 in males, 8-9 in females."
Haradon 1984b "Diagnosis.-A species in the borregoensis group of subgenus
Paruroctonus differentiated by combination of: telotarsus III with four retrosuperior setae (distal
in series may be slightly smaller than others); basitarsus III with
eight (6 + 2) superior setae (Figs. 32-33), mrs seta on basitarsus III set very close to
superior setae, all metasomal setae I-IV extremely short, inconspicuous in adult male; pectinal teeth
in female 9; pedipalp fingers of adult male moderately scalloped (Fig. 40)."
AMERICA. México (Baja California Sur): Northwestern
BAJA CALIFORNIA SUR: Paruroctonus surensis allotype and two topoparatypes, 12 km SE Guerrero Negro, 8—VIII— 1974
(R. M. Haradon, V. F. Lee, W. E. Savary); paratype (female): same locality,
18—VII— 1974; 7.8 mi. SW Guerrero Negro, 8 August 1974 (R. M. Haradon, V. F.
Lee, W. E. Savary), 3
males, 1 female (CAS),
7.8 mi. SW Guerrero Negro, 18 July 1974 (R. M. Haradon, V. F. Lee, W. E. Savary), 1 female (CAS).
notes: Haradon 1984b:
"Comparisons: Table 2. Differs further from P.
pseudopumilis and P. ventosus in having sixth and seventh supernumerary denticles on fixed
and movable fingers respectively moderately developed, distinct. Differs further from P.
ventosus in having superoterminal seta on tolotarsi I-IV long, well developed; two to three
(usually two) external medial macrosetae on distal 3/5 of humerus; proximal
enlarged denticle on movable finger about twice as long as adjacent primary denticles."
