Vaejovis montanus: Bryson et al., 2013; Contreras-Félix et al., 2015: 134.

Type material. Holotype male. MEXICO: Chihuahua, from a small ejido 5 km SW Guadalupe y Calvo, SE of Zorrillo (N 26.0398°, W 106.9396°, elev. 2625 m). VII-14-2008. Cols: R. W. Bryson Jr., M. Torocco and F. Mendoza-Quijano (CAS Type No. 18488). Examined.

Paratypes: 5 ♀, same data as the holotype (CAS), examined; 1 ♂ and 5 ♀, same data as the holotype (UANL), examined .

Diagnosis. Adult size 28.1 mm on males (Fig: 30-a, b), 26.7 to 34.2 mm on females; carapace, as long as metasomal segment V (Carapace L/MS-V 1 [0.89±0.08]) and longer than femur (Carapace L/ Femur L 1.24 [1.15±0.1). Anterior margin of carapace slightly concave, without median notch (Fig: 13-l). Mesosomal tergite VII with one pair of granular carinae, not reaching posterior margin. Pectinal teeth 11–13 [10–15]; sternite V with an elongated whitish patch reaching anterior margin, sternite VII with lateral carinae feebly granular, with 10 setae. Metasomal segment I subquadrate in dorsal view (MSI L/ W 0.80 [0.69±0.01]); intercarinal spaces on segments I–IV smooth. Segment V longer than wide (MS-V L/ W 2.21 [2.1±0.2]). Vesicle slender (L/ W 1.79 [1.7±0.01]), thin (W/D 1.21 [1.28±0.01]), on males with a well-developed vesicular gland dorsally (Fig: 14-l). Pedipalp femur (Fig: 15-l) and patella (Fig: 16-l) less than three times as long as wide (Femur L/ W 2.84 [2.58±0.1]; Patella L/ W 2.83 [2.54±0.06]). Chela longer than wide (CM L/ W 1.87 [1.76±0.04]), deeper than wide (CM W/D 0.84 [0.83±0.01]), with dorsal prosubmedian and prolateral median carinae granular (Fig: 17, 18-l). Pedipalp chela fingers on males with dentate margins straight.

Hemispermatophore (Fi: 19-l); lamella with an apical crest present about 1/3 length of lamina; wider at level of hooks; lamellar hook moderately elongated and bent at 90 degrees. Median lobe well-sclerotized, with margin dentate.

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

Distribution. Known from the type locality (Chihuahua) and has been reported from another locality in Sonora (Yecora) (Figure 4).

Natural history. This species was located under rocks and fallen logs in pine-oak forest.
