Phonotimpus separatus Gertsch & Davis, 1940: 20 , fig. 21 (female holotype from Tamazunchale, San Luis Potosí, Mexico, in AMNH; examined). Chamé-Vázquez et al., 2018: 215 , figs 1A–H.

Material examined. MEXICO: San Luis Potosí: 2.5 km N Matlapa , 21.36135°N, 98.833291°W, elev. 250 m, June 23, 2019, leaf litter, perturbed tropical deciduous forest, D. Chamé, 2♂, 3♀; (ECOTAAR-011481) , D. Chamé , 2♂, 2♀ ( AMNH), July 29, 2017, J. F. Gómez, 1♀ (ECOTAAR-009018) ; Tamazunchale , May 20, 1944, F. Bonet, 1♀ ( AMNH) ; 5 mi N Tamazunchale , July 2, 1936, A., L. Davis, 1♀ (holotype, AMNH) .

Diagnosis. Females differ from all other species by the following combination of characters: one small, shallow atrium with two very small and closely spaced copulatory openings, facing each other, a pentagonal epigynal shape, formed by the margins of the spermathecae, copulatory ducts and bursae (see figs 1E–H in Chamé-Vázquez et al. 2018 and Figs 5–7 , 16–18 ). Males differ from all other species by having the dorsal and retrolateral tibial apophyses subequal in length and thickness, both acuminate, retrolateral tibial apophysis curved basally then straight, dorsal tibial apophysis slightly arched ( Figs 1–4 , 8–11 ).

Description. Male (ECOTAAR-011481): Total length 1.22. Carapace yellow, with a few dispersed dark maculations on lateral margins, pars thoracica steeply sloping, pars cephalica gently sloping from thoracic groove to clypeus; sternum, mouthparts light yellow, each cheliceral paturon with two erect bristles near base, median bristle longer, stronger than lateral bristle; abdomen narrow, dorsum dark gray, anteriorly with scattered white spots, posteriorly with threadlike white chevrons and a white spot on anal tubercle, shiny scutum covering most of dorsum, sides light gray with longitudinal rows of white spots, venter yellow without markings ( Figs 65–68 ); legs light yellow, all unmarked. Leg spination: femora: I p0-0-2; II p0-0-1; III, IV d1-0-0; tibiae: I v4-4-2,1p; II v4-4-1p; metatarsi I v4-2-1p; II v2-2- 1p.

Palpal femur with shallow retrolateral excavation, extending over distal half of femur length, patch of spinules on distal, prolateral half ( Figs 13–14 ); dorsal tibial apophysis long, slightly arched, distally acuminate ( Figs 4 , 11 ); retrolateral apophysis long, basally curved, distally acuminate and straight ( Figs 2–3 , 10 ); tegulum expanded retrolaterally; embolar base wide, occupying about one-third of bulb width; embolus short, extending retrolaterally; embolar basal process straight, tip touching embolus; conductor short, rhomb-shaped ( Fig. 12 ); apical tegular apophysis subtriangular ( Fig. 12 ).

Female: See the redescription provided by Chamé-Vázquez et al. (2018). Epigyne (ECOTAAR-011481-MEB) with small thumblike secondary spermathecae at the beginning of second part of copulatory ducts ( Figs 17–18 ).

Distribution. Known only from the Municipios de Matlapa and Tamazunchale, in southeastern San Luis Potosí ( Fig. 339 ).
