Ommatoiulus zaghouani Akkari & Enghoff sp. n. Figs 36-39

Material.

Holotype: ♂, NE Tunisia, Zaghouan Governorate, Jebel Zaghouan, 36°23'N, 10°06E, alt. 365m, Pinus forest, 13.3.2009, N. Akkari & H. Enghoff leg. (ZMUC).

Diagnosis.

Gonopods resembling those of Ommatoiulus seurati but distinguished by a broader distal part of the promerite, a subapical lateral projection on the mesomerite and a much shorter solenomerite.

Etymology.

Named after Jebel Zaghouan, the type locality.

Description.

Male: L: 28.5 mm, H: 2.56 mm, 49 PR+1 AR+T. General colour alternate dark and light golden brown; dorsum with a thin black axial line. Head dark to blackish, with brownish spots on the frontal part and on the mandibular stipites, labral zone and mouth parts pale, marginally bright yellow; antennae brownish. Prozonites dark to blackish, covered with yellowish spots; metazonites pale brown to whitish laterally and golden brown dorsally, legs yellowish. Telson: anal valves black, preanal ring blackish, caudal projection yellowish, subanal scale yellowish.

Prozonites with fine irregular striae; metazonites with regular striae, becoming dense laterally, suture complete, curving at the level of ozopores; ozopores small, rounded, situated in metazonites, situated at about their diameter from the suture. Anal valves setose, with 4-6 setae on the surface, ca 14 submarginal and numerous marginal setae; subanal scale rounded and setose; preanal ring with 2+2 setae on the sides, protruding in a caudal projection with (6-7)+(6-7) setae on the tip and bearing a small hyaline process.

Male sexual characters. Mandibular stipites expanded in rounded posterior-ventral lobes, first pair of legs hook-shaped, remaining legs with postfemoral and tibial pads.

Gonopods. Promerite (Fig. 36) proximally subrectangular, strongly narrowed distally by a deep incision (i) on the lateral margin; mesal ridge (M) broad, distally protruding in a serrated edge (se); apical part with a mesal triangular blunt process (rp) protruding mesodistad, and a lateral protruding process with two small apical bumps (bp1, bp2); posterior surface of promerite showing few scattered setae near the mesal margin; remnant of telopodite (T) large and ovoid, located at mid-length of the process.

Posterior gonopod (Figs 37-39): Mesomerite (Ms) large, and uniformly broad (Figs 37, 38) with a distal triangular pointed extension on the lateral margin (tp), distal third strongly curved mesoposteriad and narrowed in a long and slender apical process (Figs 37, 38, 39); solenomerite (S) broad, with scattered setae on posterior margin; anteriorly simply rounded devoid of processes; apically with a hyaline folded lamella (fl) and a slightly protruding process (ds) housing the distal part of the seminal groove (g); the latter running from the fovea (F) (Fig. 37) up to process ds. Paracoxite (Px) stout and curved apically slightly narrowing into a rounded apex directed mesad, coxite broad (Co) (Fig. 39).

Distribution.

Semi-arid bioclimatic zone in northeastern Tunisia; known only from Zaghouan Mountain.

Habitat.

Forest dominated by Pinus halepensis .
