Ommatoiulus SP.6 – Bailey & De Mendonça (1990).
Diagnosis
Most similar to O. alacygni sp. nov. and O. staglae sp. nov., but differs by the three-digitate shape of the anterior process of the solenomerite and the strong serrations on the lateral margin of the paracoxite.
Etymology
The species epithet is a Latin adjective meaning “with small teeth” and refers to the serrations on the lateral margin of the paracoxite.
Material examined
Holotype
PORTUGAL: 1 ♂, Beja District, Mértola, in Pine litter, 15. May 1985, P. Bailey leg. (ZMUC).

Description
MEASUREMENTS. Male: L = 27.7 mm, H = 2.5 mm, 45 PR+3 AR+Telson. Female: L = 27.8 mm, H = 2.6 mm, 47 PR+2 AR+Telson.
COLOUR. Brownish, probably faded after more than 30 years in alcohol. Prozonites pale grey with black sputter, posteriorly forming dorsal triangular spots; metazonites yellowish-brown, with a black sputter posteriorly and scattered setae near the posterior margin (Fig. 9 A); dorsum with a thin black mid-dorsal line; legs pale brown to yellowish; head dark brown with dense black sputter, lighter towards the labral zone, mouthparts yellowish; antennae and telson dark, with a dense black sputter. Prozonites with narrow oblique striae; metazonites with regular striation; suture complete, rectilinear but sometimes with a sinus at ozopore level. Anal valves with a marginal row of short setae, a submarginal row of longer ones and ca 5 setae on the disc. Subanal scale triangular, pointed and setose. Preanal ring (Fig. 9 B) with 2 setae on the sides, a protruding caudal projection bearing ca 8 setae and a small hyaline straight projection.
GONOPODS (FIGS 9C–F, 10). Promerite (P) in posterior view broad at the base, gradually narrowing distad, lateral margin rounded; mesal ridge (Mr) broad and fusing with the mesal margin; rudimentary telopodite (T) not conspicuous. Posterior gonopod: mesomerite (Ms) simple and very reduced; solenomerite (S) complex, broadest at the base, showing an large anterior process (Sa) apically ramified in 3 asymmetrical tips and bearing a subapical median triangular hyaline lamella (Hl); posterior process of the solenomerite (Sp) long with an acuminate tip lodging the opening of the seminal groove 'og'; seminal groove (g) running from the fovea (F) located at the base of the solenomerite up to og; paracoxite (Px) large, twisted meso-posteriad, distally leaf-shaped with a pointed apex and showing strong serrations on the lateral margin; coxa (Cx) large and rounded.
Distribution
Southeast Portugal, Mértola.
