Figures 177–179 , 214–217

Type material. Female holotype taken at Cuauhtémoc, Purificación area, elev. 2100–2200 m, Tamaulipas, Mexico (Mar. 22, 1988; D. Pate), deposited in AMNH .

Other material examined. One female taken with the holotype ( AMNH) .

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

Diagnosis. Females can be recognized by having a deep atrium, anteriorly divided, atrial hood wide, produced only slightly at midline; copulatory ducts shorter than tube-shaped primary spermathecae, which are anterior to atria and lateral to semicircular, almost contiguous bursae; long fertilization ducts posteriorly directed, about the same length as primary spermathecae, almost touching posterior epigynal margin ( Figs 177–179 ).

Description. Male: Unknown.

Female (holotype): Total length 2.13. Carapace brown, with darkened lateral margins, dusky markings covering most of surface except for posterior portion of pars cephalica, pars thoracica steeply sloping, pars cephalica sloping evenly from thoracic groove to clypeus; sternum, mouthparts light brown, unmarked, except cheliceral paturons with proximal two-thirds of anterior surface darkened, each cheliceral paturon with two erect bristles near base; abdomen with dorsum, sides dark gray, with oblique rows of small white spots plus large, wide, hexagonal white spot immediately above spinnerets, scutum light brown, shiny, triangular, restricted to cardiac area, venter light gray, unmarked ( Figs 214–217 ); legs light brown, femora with lateral dark markings, posterior patellae, tibiae with weak distal dark rings. 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 v2-2-3.

Epigynum large, with a deep atrium anteriorly divided, atrial hood wide, produced posteriorly only slightly at midline; copulatory openings beneath anterolateral sides of hood, widely separated; copulatory ducts shorter than spermathecae; bursae large, semicircular, almost contiguous, occupying most of epigynum anterior half; primary spermathecae narrow, tube-shaped, about as long as bursae, located anterior to atrium, lateral to bursae; long, slender fertilization ducts, posteriorly directed, about as long as primary spermathecae, almost reaching posterior epigynal margin ( Figs 177–179 ).

Distribution. Known only from the Municipio de Güémez in central Tamaulipas ( Fig. 339 ).
