Figs 61–64  
 Materiel. Holotype: 1 ♂, Andalusia, Jaén, Sierra Cazorla, Cabañas, alt. 1900 m, 26.iv.1986, Meregalli leg. (MCSNV). Paratypes: 3 ♀♀, same data as the holotype, Meregalli leg. (MCSNV).   
 Diagnosis. Similar to O. baenai n. sp. in the general shape of the gonopods but characterized by a slenderer promerite with a more protruding lateral apical process, a slenderer mesomerite devoid of subapical processes, and details in the distal part of the solenomerite showing additionally a subapical tooth (St), an acuminate curved process (ac) and an anterior saw-like process (not with a pointed tip as in O. baenai n. sp.).   
 Etymology. The species epithet refers to the type locality of the species, the province of Jaén.   
 Description. L: 25 mm, H: 2.1 mm, 53 PR+1 AR+T. Females: L 28.5–37.5 mm, H: 2.7–4.1 mm, 50–53 PR+2 AR+T. General colour yellowish, perhaps faded after a long stay in alcohol, dorsum greyish with a thin black longitudinal line, lateral sides below the line of the ozopores yellowish. Head: dark brown on the occipital part, yellowish toward the labral zone. Labral margin and mouthparts bright yellow. Eyes composed of ca. 34 black ocelli in 9 vertical rows. Prozonites pallid greyish; metazonites yellow showing a regular striation; ozopores rounded, opening behind the suture; the latter rectilinear, sometime curving at ozopore level.   
Telson: Preanal ring yellowish with a caudal projection bearing 2+2 setae and a hyaline tip; subanal scale setose; anal valves yellowish with 5–6 setae on the surface, a marginal row of several short setae and a submarginal row of longer ones.  
 Gonopods: Promerite (Fig. 61) subrectangular (comparable to O. baenai) but narrower and more elongate, apically protruding in a lateral slender digit-shaped process (Dg); mesal ridge (Mr) broad, apically folded and protruding but not extending beyond the apical margin. Rudimentary telopodite (T) conspicuous, triangular, located distally. Posterior gonopod (Figs 62–64): Mesomerite (Ms) a simple rod, uniformly broad and slightly longer than promerite (Figs 62, 63), straight, bearing no apical projections; solenomerite (S) broad at base, constricted at midlength and strongly expanded distally as broad lamella bent laterad (Fig. 62); basal surface of solenomerite thickened and serrated anteriorly, bearing several spines protruding in an anteromesal jagged lamella (jl) to midlength of the process (Fig. 62); distal part complex, ramified into: 1) a conical process (Cn) bearing several striae on the surface, 2) a mesal folded process (Tg) lodging the opening of the seminal groove and with two pointed tips pointing apicad, 3) a strong submarginal tooth (St), 4) an acuminate curved, serrated process (ac) pointing laterad, and 5) a posterior, saw-like process (Swp) bearing asymmetrical strong teeth. Seminal groove (g) running posteriorly from the fovea (F) located at the base up to process Tg (Figs 62, 64). Paracoxite (Px) stout, of the same length as the solenomerite, with irregular anterior margin, uniformly broad and apically strongly bent (Figs 62, 63).   
 Distribution. Known only from the type locality in Jaén, Andalusia.
