original
description:
subsequent accounts:
Haradon (1984a,
1985) referred this species to the baergi
microgroup in the boreus infragroup of the genus Paruroctonus (then
recognized as the nominate subgenus of a more broadly
circumscribed genus Paruroctonus that included what is now
recognized as the genus Smeringerus Haradon).
Haradon (1984a,)
offered the following diagnosis:
"A species in the baergi group of
nominate subgenus Paruroctonus differentiated by: telotarsus III
with four long retrosuperior setae, and one retromedial seta (subdistal
seta, if present, inconspicuous)( Fig. 9); basitarsus III with eight to
11 (usually nine or 10) superior setae in essentially single file, mrs
seta fine and less than 1/2 as long as superior setae (Figs. 5-6);
humeral macrosetae include two inframedials on proximal 3/5 of internal
surface (Fig. 13), and two medials on distal 3/5 of external surface
(Fig. 14); pedipalpal internal macrosetae include two (rarely three) on
palm, one on movable finger, and none on fixed finger (Fig. 35).
Intragroup comparisons are presented in Table 4."

1Haradon 1984a
notes:
Per Haradon (1984a), the pectinal tooth count range, which
he reports as
relatively narrow among most other congeneric species, exhibits in P.
baergi a striking clinal increase from the type locality in northwestern
Sonora northward to near Cadiz Dry Lake (San Bernardino County) in
California. Haradon (ibid.) therefore expanded the original concept of this species, to
include pectinal tooth counts up to 22 (not just 13-16) in females, and up
to 29 (not just 20-24) in males. Haradon's diagnosis is based upon a paratopotypic sample (CAS), as well as specimens from the localities listed
in Haradon (1984a).
