Type material. Male holotype and female allotype taken in a baited pitfall trap set in a forest at the Chipinque Mesa, elev. 1646 m, Monterrey, Nuevo León, Mexico (June 21–25, 1969; S., J. Peck), deposited in AMNH.
Other material examined. MEXICO: Nuevo León: Chipinque, Monterrey, July 15, 1942, C. Bolivar, F. Bonet, B. Osorio, D. Peláez, 4♀ (AMNH), Dec. 2, 1943, F. Bonet, 1♀ (AMNH). Chipinque Mesa, elev. 1646 m, Monterrey, June 21–25, 1969, human dung trap, forest, S., J. Peck, 2♂ (AMNH).
Etymology. The specific name is a noun in apposition taken from the type locality.
Diagnosis. Males resemble those of P. arcitos sp. nov. and P. tetrico sp. nov. but the apex of the retrolateral tibial apophysis is partially truncated and has a small, pointed tip (Figs 164–165). Females have an epigynum resembling that of P. eutypus, but have tubular primary spermathecae slightly wider posteriorly, reaching almost the posterior epigynal margin, longer than copulatory ducts (Figs 167–169). The carapace has a dusky U-shaped mark (Figs 134, 138).
Description. Male (holotype): Total length 2.05. Carapace yellow, with dark lateral margins, dusky markings restricted to U-shaped wide band situated about halfway between lateral margins and unmarked median area, pars thoracica steeply sloping, pars cephalica almost flat; sternum, mouthparts yellow, unmarked, each cheliceral paturon slightly darkened, with one erect bristle near base; abdomen narrow, dorsum dark gray, with broad white marking over cardiac area, connected posteriorly with first of five white chevrons, anterior two chevrons much larger than others, anteriorly with scattered white spots, weak, shiny scutum covering about three-fourths of abdominal length, most of width, sides, venter pale yellow, unmarked (Figs 134–137); legs yellow, leg III with distal dark markings on patella, tibia, metatarsus, leg IV with distal dark marking on tibia. Leg spination: femora: I d1-0-0, p0-0-2; II–IV d1-0-0; tibiae: I v4-4-4; II v4-4-2; metatarsi I, II v3-2-2.
Palpal femur club-shaped, with one dorso-distal spine, retrolateral excavation deep, extending over distal half of femur length, patch of spinules on distal, prolateral half; dorsal tibial apophysis long, straight, narrow, extending to about one-third of cymbial length (Fig. 166); retrolateral apophysis much wider, much shorter, arched toward venter, apex truncated with small pointed tip (Figs 164–165); distal border of palpal tibia deeply notched prolaterally (Figs 163–164); tegulum bulbous, projecting ventrally; embolar base membranous, occupying about one-fifth of bulb width; embolus short, narrow, weak, situated in the margin of alveolus, obscured by cymbial setae; embolar basal process distally touching embolus; conductor relatively long, narrow, tip widened; apical tegular apophysis slender, hook shaped, tip blunt, pointing retrolaterally (Figs 163–165).
Female (allotype): Total length 2.86.As in male, except each cheliceral paturon with two erect bristles, abdominal dorsum anteriorly with only weak, narrow cardiac white marking, abdominal scutum triangular, occupying most of front margin but extending only about one-fourth of abdominal length, covering less than one-third of abdominal width posteriorly (Figs 138–141); femur, tibia, metatarsus III each with proximal, distal dark markings, femur, patella, tibia, metatarsus IV each with distal dark markings. Leg spination as in male.
Epigynum wide, copulatory openings about one diameter apart, located about at middle length of shallow atrium; copulatory ducts tubular, sclerotized, shorter than primary spermathecae; bursae large, semicircular, longer than wide, almost contiguous posteriorly; primary spermathecae tubular, slightly wider posteriorly, almost reaching posterior epigynal margin, about the same length as bursae and lateral to copulatory ducts (Figs 167–169).
Distribution. Known only from the Municipio de Monterrey in northern Nuevo León, where it is sympatric with P. boneti sp. nov. (Fig. 339).
