description: Phonotimpus cumbres sp. nov.
Figures 38–44, 81–88
Type material. Male holotype and female allotype taken at 1 km W Altas Cumbres, Ciudad Victoria, 23.60017°N, 99.21497°W, elev. 1350 m, Tamaulipas, Mexico (July 14, 2006; R. Anderson, L. Benavides), deposited in MCZ (140480).
Other material examined. One male and three females taken with the types (MCZ).
Etymology. The specific name is a noun in apposition taken from the type locality.
Diagnosis. This species seems close to P. farias sp. nov. and P. perra sp. nov. but males have the distal half of retrolateral tibial apophysis sharp, triangular in retrolateral view (Figs 39–41) and females have small, circular copulatory openings and rounded primary spermathecae separated by one diameter respectively (Figs 42–44).
Description. Male (holotype): Total length 1.54. Carapace yellow, with dark lateral margins, two wide, paramedian bands of dark, radiating maculations, pars thoracica gently sloping, pars cephalica flat; sternum, mouthparts yellow, each cheliceral paturon with two erect bristles near base, median bristle longer, stronger, than lateral bristle; abdomen narrow, dorsum, sides dark gray, posterior two-thirds with five white chevrons, most anterior chevron largest, others decreasing in size toward spinnerets, all chevrons difficult to distinguish under strong scutum covering almost full length of abdomen, chevrons more obvious on sides, venter white, unmarked (Figs 81–84); legs yellow, femora, patellae, tibiae with weak distal dark rings. Leg spination: femora: I d1-0-0, p0-0-2; II d1-0-0, p0-0-1; III–IV d1-0-0; tibiae: I v4-4-3; II v4-4-1p; metatarsi I, II v2-2-3.
Palpal femur with retrolateral excavation extending over distal half of femur length, patch of spinules on distal, prolateral half; dorsal tibial apophysis long, narrowing smoothly to tip; retrolateral apophysis much stronger, wide at base, abruptly narrowed at about half its length, triangular and sharp in retrolateral view (Fig. 40); tegulum slightly expanded proximally; about one third of embolar base sclerotized, the rest membranous; embolus short, tubular, weak, extending obliquely toward retrolateral edge of alveolus, obscured by embolar basal process, which ends at embolus tip; conductor short, widened at apex; hook-shaped apical tegular apophysis (Fig. 39).
Female (allotype): Total length 2.35. As in male, except dorsal abdominal scutum narrow, restricted to cardiac area, flanked by two paramedian, rounded white spots (Figs 85–88), distal leg rings much weaker on anterior legs than posteriors. Leg spination as in male except tibiae: I v4-4-4; II v4-4-2.
Epigynum wide, with pair of dark, circular copulatory openings, each situated on a shallow atrium, separated by their diameter, just anterior of spermathecae in posterior half of epigynal length; bursae large, subtriangular, contiguous; rounded primary spermathecae small, separated by their diameter, restricted to posterior quarter of epigynum length; secondary spermathecae fingerlike, lateral to copulatory ducts (Figs 42–44).
Distribution. Known only from the Municipio de Victoria in central Tamaulipas (Fig. 339).
