Ommatoiulus jaenensis Akkari & Enghoff n.sp.

Figs 61–64

Materiel. Holotype: 1 ♂, Andalusia, Jaén, Sierra Cazorla, Cabañas , alt. 1900 m, 26.iv.1986, Meregalli leg. ( MCSNV) . Paratypes: 3 ♀♀, same data as the holotype, Meregalli leg. ( MCSNV) .

Diagnosis. Similar to O. baenai n. sp. in the general shape of the gonopods but characterized by a slenderer promerite with a more protruding lateral apical process, a slenderer mesomerite devoid of subapical processes, and details in the distal part of the solenomerite showing additionally a subapical tooth (St), an acuminate curved process (ac) and an anterior saw-like process (not with a pointed tip as in O. baenai n. sp.).

Etymology. The species epithet refers to the type locality of the species, the province of Jaén.

Description. L: 25 mm, H: 2.1 mm, 53 PR+1 AR+T. Females: L 28.5–37.5 mm, H: 2.7–4.1 mm, 50–53 PR+2 AR+T. General colour yellowish, perhaps faded after a long stay in alcohol, dorsum greyish with a thin black longitudinal line, lateral sides below the line of the ozopores yellowish. Head: dark brown on the occipital part, yellowish toward the labral zone. Labral margin and mouthparts bright yellow. Eyes composed of ca. 34 black ocelli in 9 vertical rows. Prozonites pallid greyish; metazonites yellow showing a regular striation; ozopores rounded, opening behind the suture; the latter rectilinear, sometime curving at ozopore level.

Telson: Preanal ring yellowish with a caudal projection bearing 2+2 setae and a hyaline tip; subanal scale setose; anal valves yellowish with 5–6 setae on the surface, a marginal row of several short setae and a submarginal row of longer ones.

Gonopods: Promerite ( Fig. 61) subrectangular (comparable to O. baenai ) but narrower and more elongate, apically protruding in a lateral slender digit-shaped process (Dg); mesal ridge (Mr) broad, apically folded and protruding but not extending beyond the apical margin. Rudimentary telopodite (T) conspicuous, triangular, located distally. Posterior gonopod ( Figs 62–64): Mesomerite (Ms) a simple rod, uniformly broad and slightly longer than promerite ( Figs 62, 63), straight, bearing no apical projections; solenomerite (S) broad at base, constricted at midlength and strongly expanded distally as broad lamella bent laterad ( Fig. 62); basal surface of solenomerite thickened and serrated anteriorly, bearing several spines protruding in an anteromesal jagged lamella (jl) to midlength of the process ( Fig. 62); distal part complex, ramified into: 1) a conical process (Cn) bearing several striae on the surface, 2) a mesal folded process (Tg) lodging the opening of the seminal groove and with two pointed tips pointing apicad, 3) a strong submarginal tooth (St), 4) an acuminate curved, serrated process (ac) pointing laterad, and 5) a posterior, saw-like process (Swp) bearing asymmetrical strong teeth. Seminal groove (g) running posteriorly from the fovea (F) located at the base up to process Tg ( Figs 62, 64). Paracoxite (Px) stout, of the same length as the solenomerite, with irregular anterior margin, uniformly broad and apically strongly bent ( Figs 62, 63).

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