Figures 189–191 , 230–233

Type material. Female holotype from the Cueva de Rancho Revilla [23.9401223°N, 99.4803097°W], Tamaulipas, Mexico (Aug. 22, 1973; D. McKenzie, R. Jameson) , deposited in AMNH; the label reads Nuevo León , but according to Barr (1982: 174, fig. 47), the Cueva de Rancho Revilla is also called the Cueva de Revilla (see Other Material Examined below) and is in Tamaulipas, Mexico .

Other material examined. MEXICO: Tamaulipas: Cueva de Revilla [23.9401223°N, 99.4803097°W], Revilla, Purificación area , Apr. 19, 1980, T . Treacy et al., 1♀ ( AMNH) .

Etymology. The specific name is a noun in apposition taken from the type locality.

Diagnosis. The epigynum of this cave species resembles that of the surface species P. cuauhtemoc sp. nov. but can easily be distinguished by its straight, anterior margin of atrium, without hood, posterior third with median septum, copulatory openings evident, copulatory ducts about as long as primary spermathecae, shorter fertilization ducts, far from posterior epigynal margin ( Figs 189–191 ).

Description. Male: Unknown.

Female (holotype): Total length 2.25. Carapace yellow, with only vague traces of submarginal bands of maculations, pars thoracica steeply sloping, pars cephalica flat; sternum, mouthparts yellow, unmarked, each cheliceral paturon with two strong, erect bristles near base; abdomen narrow, dorsum, sides light gray, with scattered tiny white spots plus large white mark immediately above spinnerets, scutum wide, covering full width of abdomen anteriorly, extending to about one-third of abdomen length, where covering about half of abdomen width, venter white, unmarked ( Figs 230–233 ); legs yellow, unmarked. 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 v4-2-2; II v2-2-3.

Epigynum very large, posterior half with a deep atrium extending over entire epigynal width, posterior third with elevated, median septum; widely separated copulatory openings at anterior margin of atrium; long, tubular, heavily sclerotized copulatory ducts anterolaterally directed, about same length as primary spermathecae; bursae large, semicircular, almost contiguous; primary spermathecae tubular, about as long as bursae, anterior to atrium, lateral and parallel to copulatory ducts; fertilization ducts slender, directed posteriorly, about half as long as primary spermathecae, ending far from posterior epigynal margin ( Figs 189–191 ).

Distribution. Known only from the Cueva de Rancho Revilla (=Cueva de Revilla) in the Purificación area, Municipio de Güémez, Tamaulipas ( Fig. 339 ).
