type(s) :  Vejovis (Paruroctonus) baergi Williams & Hadley - Holotype male (adult) from México, Sonora, Cholla Bay, near Puerto Peñasco, 15 October 1966 (S. C. Williams). Depository: California Academy of Sciences (CAS), Type No. 9479.

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."

Haradon 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).
