Figs 78–81

Material. Holotype: 1 ♂, Andalusia, ca. 3 Km SW Aldeaquemada, Jaén , 38º23'53''N, 3º24'W, 7.iii.2012, E. Recuero leg. ( ZMUC).

Diagnosis. Species similar to O. baenai n. sp., O. inconspicuus and O. niger in the shape of the promerite, mesomerite and voluminous solenomerite, but differing from these species by the shape of the mesal apical process of the promerite and the presence of two accessory branches on the solenomerite as well as by the shape of the paracoxite.

Etymology. Species named in honour of Ernesto Recuero, collector of the species.

Description. Male: L: 40 mm, H: 2.7 mm, 53 PR+2 AR+T. General dark brown. Below the line of ozopores, metazonites with a narrow light band anteriorly and dark brown posteriorly, dorsally dominantly light brown; prozonites dark brown to black. Head: dark brown on the occipital and labral zone, much darker to blackish around the ocellar fields and between the antennae. Antennae and mandibular stipes tawny brown; collum blackish. Legs and mouthparts light tawny brown. Anal valves, subanal scale and preanal ring blackish. Metazonites with regular striation and scattered slender setae at posterior margin, ozopores opening at a distance ca. ½ their diameter behind suture, suture complete, curving at ozopore level, especially on the anterior rings; prozonites with conspicuus oblique striae.

Telson: Preanal ring with a protruding horizontal setose projection with a hyaline tip; subanal scale triangular, protruding, with numerous setae; anal valves with a marginal row of short setate, a submarginal row of longer ones and 5–6 setae on the surface.

Gonopods. Promerite ( Fig. 78) subrectangular, elongate, twice as broad as long, apically protruding in a lateral globulous digit-shaped process (Dg) with scaly surface; mesal ridge (Mr) uniformly broad, folded up and apically protruding, rudimentary telopodite (T), triangular, located distally. Posterior gonopod ( Figs 79–81): Mesomerite (Ms) slender, elongate, slightly curved mesad and apically bent, bearing two small spikes (h1, h2) pointing posteriad ( Fig. 80); Solenomerite (S) complex, broad and bearing anteriorly two accessory branches (Sb1, Sb2) both apically tapering and strongly curved ( Fig. 81); Sb1 very strongly curved, with bifurcate tip ( Fig. 79). The main process (S) broad, slightly narrowed at mid-length ( Fig. 80), apically expanding in a broad lamella with a posterior conical blunt lobe (Cn) bearing a few serrations on the apex and a anterior folded lamella composed of a triangular mesal, apically acuminate, curved process (Sc1) connected to a posterior acuminate, jagged process (Sc2) which is strongly bent downwards and lodges the opening of the seminal groove ( Figs 80, 81). The latter (g) running from the fovea (F) mesoposteriorly up to the apical posterior downturned process of the solenomerite ( Fig. 78). Paracoxite (Px) broadest at the basis, distally uniformly broad, apically expanding in a crescent-shaped process with two oppositely directed tips (Px1, Px2) ( Figs 79, 81).

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