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.
