Figs 3–6

Material. Holotype: 1 ♂, Andalusia, Casas de Carrasco, Jaén , 38º07'43"N, 2º41'19"W, alt. 1420 m, 2.iv.2012, M. Baena leg. ( ZMUC) . Paratype: 1 ♀, same data as holotype ( ZMUC) .

Diagnosis. Similar to O. albolineatus parvus ( Brolemann, 1920) , O. bavayi ( Brölemann, 1897) , O. ibericus Ceuca, 1974 , and O. niger ( Attems, 1952) in the shape of the promerite and mesomerite, differing however from the first two taxa in the shape of the paracoxite and from the rest in the shape of the distal part of the solenomerite with a strongly bent mesal process lodging the opening of the seminal groove and a jagged and acuminate anterior process.

Etymology. Species named in honour of Manuel Baena, collector of the species.

Description. Male: L: 27 mm, H: 2.0 mm, 49 PR+2 AR+T. Female: 50 PR+3 AR+T. Colour dark greyblackish. Prozonites uniformly sputtered with gray, metazonites golden brown, darker posteriorly, dorsum with a thin black mid-dorsal line, legs brownish, head dark brown, lighter on the frontal part, mouthparts yellowish, telson dark brown. Prozonites with scattered oblique striae; metazonites with regular striation and short setae on the posterior margin, suture complete, rectilinear and sometimes curving at ozopore level. Telson: anal valves with 1 marginal row of short setae, a submarginal row of longer ones and ca. 6 setae on the disc; subanal scale triangular, pointed and setose; preanal ring with a protruding caudal projection, setose and bearing a small hyaline process and 2–2 setae on the lateral sides.

Gonopods. Promerite ( Fig. 3) subrectangular, apically protruding in a lateral slender digit-shaped process (Dg); mesal ridge (Mr) broad, protruding apically, separated from lateral process by an apical notch. Rudimentary telopodite (T) broad, rounded and located distally. Posterior gonopod ( Figs 4–6): Mesomerite (Ms) uniformly broad and slightly longer than the promerite, bearing two apical projections (h1, h2) ( Figs 4, 6); solenomerite (S) broad at the base, narrowing at midlength and strongly expanding distally in broad lamella bent basolaterad; basal surface of solenomerite also thickened and serrated anteriorly, bearing several spines protruding up to midlength of the process in an anteromesal jagged lamella (jl); distal lamella ramified into: 1) a posterior conical process (Cn), apically acuminate and serrated, 2) a mesal folded strongly invaginated process (Tg), containing the opening of the seminal groove (g), curved in the middle and bearing two extremities pointing laterally, 3) a posterior process with a jagged margin ending in acuminate tip pointing distolaterad (Sp). Seminal groove (g) running posteriorly from the fovea (F) ( Fig. 4) located at the base up to the apical folded process (Tg). Paracoxite (Px) stout, broadest at the base, slightly narrowed distally, apically expanding in a rounded apex with irregular margin bent basomesad.

Distribution. Known only from the type locality in Jaén Province, Andalusia.
