W. Bryson Jr., M. Toroccoand 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 mmon males (Fig: 30-a, b), 26.7 to 34.2 mmon 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 typelocality ( 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. 2237797923 2008-07-14 CAS Cols & R.
