Diagnosis. Adult size from 17 to 28 mm (Fig: 46-a, b). Carapace (Fig: 35-f) on males shorter than metasomal segment V (Carapace L/MS-V 0.88±0.08 [1.02±0.1]), but longer than femur (Carapace L/Femur L 1.23±0.1 [1.3±0.06]); anterior margin of carapace slightly concave. Mesosomal tergite VII bearing two pairs of strong, granular carinae, beginning on middle of segment and not reaching posterior margin. Pectinal teeth 15–16 [13–15]; sternite V with a white, semi-oval patch along posterior margin; sternite VII with one pair of vestigial carinae, almost absent, and 16–21 (20) [12–19 (18)] setae. Metasomal segment I wider than long, rectangular in dorsal view (MSI L/ W 0.7 ±0.06 [0.56±0.04]); intercarinal spaces on segments I–IV smooth; on segment V feebly granular (MS-V L/ W 1.91 ±0.09 [1.71± 0.05]; W/D 1.13±0.1 [1.16±0.05]). Vesicle (Fig: 36-f) slender (L/ W 1.79 ±0.17 [1.65±0.6]) and thin (W/D 1.25±0.03 [1.31±0.13]), ventral surface smooth; dorsal surface with a small, whitish vesicular gland posteromedially (Fig: 36-f). Pedipalp femur (Fig: 37-f) on males three times longer than wide, on females slightly shorter (L/ W 3.04 ±0.1 [2.77±0.1]); patella (Fig: 38-f) less than three times as long as wide (L/ W 2.85 ±0.2 [2.68±0.2]; W/D 1.2±0.08 [1.25±0.1]), with external carina weak, almost absent; dorsal internal carina inconspicuous, composed of irregular line of granules. Chela (Fig: 39, 40-f) thin (CM L/ W 2.17 ±0.1 [2.38±0.2]; W/D 0.92±0.08 [0.98±0.1]; CM L/FF 1.49±0.2 [1.34±0.3]); dorsal internal carina feebly granular. Pedipalp chela fingers dentate margins straight, without scalloping.

Hemispermatophore (Fig: 41-f): Lamelliform (TL 2.5; LL 1.5; LW 0.4 mm); lamella simple, without distal crest, narrower at level of hooks; one pair of hooks located basally, lobe-shaped. Capsular mesal median lobe present.

Full morphometric variation is given in tables 13 and 14. Setae variation is given in table 9–12.

Distribution. This species is only known from the mountains of the Sierra Juarez, in Oaxaca (Figure 4).

Natural history. This species inhabits in pine forests; it can be found under rocks and fallen logs.
