Measurements and ratios. Male holotype: Body 1.30. Carapace 0.47/0.42 (1.1). Pedipalp: femur 0.71/0.11 (6.3), patella 0.31/0.13 (2.4), chela 1.01/0.16 (6.2), hand 0.40 (2.4), movable finger 0.61; ratio movable finger/hand 1.5, femur/movable finger 1.2, femur/carapace 1.5, chela/carapace 2.1, chela/femur 1.4. Female topotype: Body 1.41. Carapace 0.50/0.42 (1.2). Chelicera 0.46/0.22 (2.1), movable finger 0.25. Pedipalp: femur 0.72/0.12 (6.3), patella 0.33/0.14 (2.4), chela 1.06/0.18 (5.9), hand 0.42 (2.3), movable finger 0.64; ratio movable finger/hand 1.5, femur/movable finger 1.1, femur/carapace 1.4, chela/carapace 2.1, chela/femur 1.5.

Remarks. Within the verai -group, O. cazorlensis (Carabajal Márquez, García Carrillo & Rodríguez Fernández, 2001) shares with O. hoerwegi n. sp., O. mateui n. sp. and O. riopar n. sp. the presence of only 3–8 rounded vestigial teeth, without dental canals, in the basal half of the movable chelal finger. It differs from O. riopar n. sp. in having the movable chelal finger with 14–16 pointed teeth and trichobothrium ist distinctly proximad of lyrifissure fb, versus movable finger with only 12 pointed teeth and trichobothrium ist level with lyrifissure fb in O. riopar n. sp. O. cazorlensis differs from O. hoerwegi n. sp. and O. mateui n. sp. in having cheliceral lyrifissure ldb. The above description incorporates in part those of Carabajal et al. (2001c) and Pérez & Zaragoza (2010).
