Material. Holotype: 1 ♂, Andalusia, Córdoba, Cerro de la Mazura, Luque , 37º35'09"N, 4º10'01"W, alt. 385m, 10.03.2012, M. Baena leg. ( ZMUC) ; Paratypes: 1 ♂, Andalusia, North side of Grazalema between Zahara de la Sierra and Grazalema in the mountain area of Los Cambroneros above Garganta Verde , 36º48'38''N, 5º23'42''W, alt. 680 m, under stones, 6.ii. 2008, H. Reip & K. Voigtländer leg. ( ZMUC) ; 1 ♂, in litter, beneath bush on limestonerocky hillside, near El Pedroso, ca. 170 Km East of Sevilla , 11.x.1986, P.T Bailey leg. ( ZMUC) .

Diagnosis. Similar to O. bavayi in the general shape of the promerite, mesomerite and paracoxite; characterized, however, by a less sinuous paracoxite and a broader and more complex solenomerite bearing several distal processes (only 3 processes in O. bavayi ) and displaying a complete different configuration.

Etymology. Species named in honour of one of the collectors, Hans Reip, for his active contribution to the revision of genus Ommatoiulus and the present project with samples, literature and illustrations.

Description. Male: L: 25 mm, H: 2.0 mm, 45 PR+1 AR+T. General colour dark brown, dorsally alternated with light brown to yellowish. Head on the frontal part and collum dominantly dark brown, light brown toward the labral zone. Prozonites blackish with scattered rounded-oval pale spots on either sides of a thick, black mid-dorsal line; dorsum overlaid by series of big black spots. Preanal ring and anal valves black, subanal scale brownish. Metazonites with scattered slender setae at posterior margin, showing narrow striation, becoming scarser on the sides, ozopores small, rounded, opening at a distance ca. their diameter behind suture, latter complete, rectilinear; prozonites with scarse oblique striae.

Telson: Preanal ring with a protruding horizontal caudal projection bearing 5+5 setae and a hyaline tip, 4+4 on the sides; subanal scale with a pointed triangular apex and several setae; anal valves with (5–7)+(5–7) long setae on the surface, a marginal row of several short setae and a submarginal row of ca. 20+20 longer ones.

Gonopods. Promerite (P) subrectangular ( Figs 82, 83), elongate, twice as broad as long, apically protruding in a lateral digit-shaped process (Dg) with scaly surface; mesal ridge (Mr) uniformly broad, folded up, and protruding distally, rudimentary telopodite (T) conspicuous, triangular and located distally. Posterior gonopod ( Figs 82, 84, 85): Mesomerite (Ms) simple, uniformly slender, slightly longer than the promerite ( Figs 83, 84), apically domed with a folded apex bearing two small subapical hooks pointing anteriad and mesad, respectively; solenomerite (S) broadest at the basis, apically with a hyaline rounded lobe (Hl) and a bipartite (bullhorn-shaped) process lodging the opening of the seminal groove ( Fig. 84), with a small process tapering distad (Dp) and a curved one pointing anteriad (Cp); seminal groove (g) running from the fovea (F), up to the bipartite process; parasolenomerite (Ps) short, apically acuminate, pointing distad and separated from the solenomerite by a distolateral hyaline lamella bearing a small pointed process (w1) on the margin. Paracoxite (Px) large, with a broad base, narrowed sub-basally, narrowing towards tip, apically with a curved margin, tapering and bearing several serrations; posterior margin folded, anterior margin at midlength expanded in a triangular lobe (Tl) ( Fig. 85).

Distribution. Known from Córdoba and Sevilla in Andalusia.

Habitat. Leaf litter of oak forests with Quercus suber and Quelcus ilex ( Bailey and De Mendonça 1990) , also found under stones in oak forests with undergrowth of Sorbus , Juniperus and Salix .

Comments. The similarities in the general shape of O. reipi and O. bavayi described by Brölemann (1897) from Murcia (southern Spain) were striking, however, the study of the holotype (MNHN) of O. bavayi has revealed a number of differences, especially in the shape of the solenomerite which is much broader and bearing more processes in O. reipi while in O. bavayi , the solenomerite distally bears 3 processes: the anteriormost is long and acuminate, extending beyond the rest of processes, the mesal process (lodging the seminal groove) is simple (not bipartite) and the posteriormost conical process is low and separated from the rest by a deep notch (see also Brölemann 1897: figs I–IV).
