Diagnosis. Most similar to O. albolineatus parvus , O. ibericus and O. hoffmani n. sp. in the general shape of the gonopods, different from O. a. parvus by the shape of the paracoxite and from O. ibericus and O. hoffmani by the distal part of the solenomerite.

Description. Males: L: 22 mm, H: 1.9 mm, 49 PR+1 AR+T. Females: L: 32 mm, H: 3.1 mm, 54 PR+ 2 AR+T. Colour brownish, dorsally with alternation of pale to light brown and blackish with white marbling. Prozonites black with lateral areas of light yellowish marbling, metazonites whitish anteriorly, light brown medially and darker to black with yellow marbling posteriorly, dorsum with big triangular spots at mid-dorsal line, legs purple, head dark brown and telson blackish. Telson: anal valves with 1 marginal row of short setae, a submarginal row of longer ones and 5–7 setae on the disc; subanal scale triangular, pointed and setose; preanal ring with a protruding, setose caudal projection bearing a small hyaline process and 1–2 setae on the lateral sides.

Gonopods: Promerite (P) sub-rectangular ( Fig. 69), uniformly narrow, mesal ridge (Mr) broad, running up to the distal part and folded up, laterally with an apical digit-shaped apex, rudimentary telopodite (T) conspicuous and loated distally close to the mesal margin ( Fig. 69).

Posterior gonopod ( Figs 69–71): Mesomerite (Ms) simple, longer than promerite, slender and apically slightly curved laterad ( Figs 70–71). Solenomerite (S) broadest at the base, distally with an anteromesal, marginally serrated lamella (jl) bearing several small spikes, apically divided into 1) a anteriormost, long process (e1), subapically with a claw (Cl) and apically bent posteriad and bearing on the internal margin several spikes ( Figs 70, 71); 2) a shorter process (e2) bent posteriad, with acuminate tip lodging the opening of the seminal groove; 3) a process (e3), slightly longer than e2, triangular with a blunt tip and several striae. Seminal groove (g) running from the fovea (F) and opening in the tip of process e2 ( Fig. 70). Paracoxite (Px) basally broadest, longer than solenomerite ( Fig. 70), lateral margin truncate at mid-length, distally narrowed and apically bent into a triangular process with an acuminate tip ( Fig. 71).

Distribution. Málaga, Sierra de Ronda, Monte Arastepa; Sierra Guadarrama, Monte Cañal near Villalba ( Attems 1952). O. niger is recorded here additionally from the provinces Almería, Cadíz, Granada, Jaén and Sevilla.

Habitat. Litter of Olea europaea plantations ( Bailey and De Mendonça 1990). Here, reported from litter of low bush; in soil, under grass between limestone stones and pebbles.
