Figures 62–64, 109–112

Type material. Female holotype from Berlese sample of forest log litter taken in a coffee plantation at Tamán, 20 km SW Tamazunchale, (elev. 350 m), San Luis Potosí, Mexico (June 11, 1983; S., J. Peck), deposited in AMNH .

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

Diagnosis. The female resembles those of P. cima sp. nov., P. marialuisae and P. padillai by the origin of bursae widely separated, lateral to the copulatory openings, but P. taman sp. nov. has a distinctive median, subtriangular sclerotization, encompassing the single, deep atrium, and the first part of copulatory ducts (Figs 62–64).

Description. Male: Unknown.

Female (holotype): Total length 1.58. Carapace pale yellow, unmarked but possibly faded, as little pigmentation is detectable around eyes, pars thoracica steeply sloping, pars cephalica almost flat; sternum, mouthparts pale yellow, unmarked, each cheliceral paturon with two erect bristles near base, lateral bristle much weaker than median; abdomen narrow, pale white, unmarked but possibly faded, scutum small, triangular, covering less than one-third of abdominal width at front, extending only over anterior half of cardiac area, venter pale white with two faded, light brown longitudinal bands (Figs 109–112); legs yellow, without dark markings. Leg spination: femora: I p0-0-2; III, IV d1-0-0; tibiae I, II v3-4-2; metatarsi: I v4-2-1p, II v3-2-2.

Epigynum large, one median, deep atrium with copulatory openings at posterior margin; first part of copulatory ducts slightly sclerotized, pointing diagonally, second part very short, directed posteriorly; atrium and first part of copulatory ducts form a subtriangular shape; bursae ovoid, larger than pear-shaped spermathecae that touch posterior margin of epigynum (Figs 62–64).

Distribution. Known only from the Municipio de Tamazunchale in southeastern San Luis Potosí (Fig. 339).
