Figs 86–89  
 Materiel. Holotype: 1 ♂, Andalusia, Almería Province, Dalias, Punta del Sabinar, 29.iii.1992, A. Tinaut leg. (MNHN). Paratypes: 1 intercalary ♂, same locality as holotype, 28.v. 1992, A. Tinaut leg. (MNHN), 1 juvenile ♂, same locality as holotype, A. Tinaut leg. (MNHN), 14.iii. 1992, 2 ♀♀, same locality as holotype, 26.i.1992, A. Tinaut leg. (MNHN).   
 Diagnosis. Resembling O. gauthieri (Brolemann, 1931) from Algeria and O. cingulatus (Attems, 1927) from Portugal in having a bifurcate paracoxite; differing from these species by the complex structure of the solenomerite: thin, elongate, bearing at midlength several thorn-like processes, accompanied by two differently shaped accessory processes.   
 Etymology. Species epithet refers to Punta del Sabinar, type locality of the species.   
 Description. Males: L: 21.5– 26 mm, H: 1.8–1.9 mm, 45–46 PR+2–3 AR+T. Females: L: 22–23 mm, H: 2–2.2 mm, 45 PR+3 AR+T. General colour dark brown. Metazonites blackish brown becoming golden brown on the lateral sides below the line of the ozopores; prozonites dominantly dark brown laterally and yellowish dorsally with at the middle a big triangular spot pointing posteriad. Head: brown on the occipital and labral zone, much darker to blackish around the ocellar fields and between the antennae. Antennae and mandibular stipes brownish; collum blackish. Legs and mouthparts yellowish. Anal valves, subanal scale and preanal ring brownish. Metazonites with regular striation, ozopores opening at a distance ca. ½ their diameter behind suture, suture complete, curving at ozopore level, especially on the anterior rings; prozonite with conspicuous oblique striae laterally.   
Telson: Preanal ring with a protruding caudal projection bearing numerous setae; subanal scale triangular, pointed and setose; anal valves with a marginal row of short setae, a submarginal row of long ones and 3–4 setae on the surface.  
 Gonopods. Promerite (P) half as broad as long, gradually narrowed in the distal third (Fig 86, 87, 88), with a broad mesal ridge which fuses with the mesal margin at about midlength. Distal part slightly concave with a lateral subapical notch and an apical process (Ap) curved laterad, ending in an acuminate tip pointing anteriorly (Fig. 88). Posterior gonopod: Mesomerite (Ms) long, uniformly broad, apically bifurcating into a small blunt process pointing posterolaterad (Mp1) and a longer curved process (Mp2) pointing laterally (Figs 86, 88, 89). Solenomerite complex with a main process lodging the seminal groove (g) and two lateral additional branches emerging from the same base (j1, j2) (Figs 86, 88, 89). Main process (S) broadest at the base, distally bearing several thorns on the anterior margin (Figs 88, 89), apically protruding into an acuminate process extending beyond the rest of the gonopod and harboring the opening of the seminal groove (Figs 86, 89). The latter running from the fovea (F) located at the base, along the posterior margin of the process to the apex of the same (Fig. 86). Branch j1 anterolateral, shorter than the main process, apically expanded in a leaf-shaped hyaline process pointing posteriad (Figs 86, 88, 89); second accessory branch (j2) located anteromesally, also slender but much shorter and pointing apicad. Paracoxite (Px) broad, distally bifurcating in two asymmetrical hook-shaped processes, the mesal-most process slightly longer and apically curved (Figs 88, 89).   
 Distribution. Known only from the type locality in Almería, Andalusia.   
 Comments. J. -P. Mauriès very kindly transferred his drawings and notes to us in order to have the new species incorporated in the present work.
