Ommatoiulus xerophilus Akkari & Enghoff

Males: L: 15.7–15.9 mm, H: 1.54–1.65 mm, 44–46 PR+1–2 AR+T; females: L: 10.2–23.1 mm, H: 1.44–2.56 mm, 39–46 PR+1–4 AR+T. General colour black to brownish, light brown on the sides; dorsum pale yellow, crossed by thick black mid-dorsal spots. Head dark to blackish with yellow spots in the occipital area, frontal part uniformly black showing yellow spots at antennal level, labral zone yellowish, brighter at margin; antennae brownish. Prozonites blackish with light brown-yellowish spots becoming dominant laterally, just below the ozopore line; dorsally pale, with big, irregularly shaped black spots; metazonites predominantly grey-whitish and glossy, legs yellowish. Telson: anal valves dark brown-blackish, with dense yellow sputter, preanal ring blackish sputtered with yellow, dorsal side and caudal projection mostly pale, subanal scale yellowish. Prozonites with fine striae; metazonites with regular striae, becoming denser laterally, suture complete, curving at the level of ozopores; latter small, rounded, situated on metazonites situated at about their diameter from the suture. Anal valves setose, with 6-7 setae on the surface and numerous submarginal and marginal setae; subanal scale rounded and setose; preanal ring with 1+1 setae on the sides, protruding in a caudal projection with 3+3 setae and a small hyaline process on the tip. 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 (P) (Figs 31, 32) bent anteriad, not very broad, with parallel margins, mesal ridge (M) broad, distally narrowing and truncate, bearing several serrations (se) and separated from the apical lobe (ap); by an incision; lateral margin mostly rectilinear, only slightly narrowing subapically at the level of the mesal incision; apical lobe globular, with rounded margin, curved laterad; posterior surface with a number of strong setae aligned distally; telopodite remnant inconspicuous. Posterior gonopod (Figs 31, 33–35): Mesomerite (Ms) similar to Ommatoiulus chambiensis but broader, strongly truncated and distally bent mesad (Figs 33–35); solenomerite (S) broad, with scattered setae on posterior margin, strongly narrowing at mid-length, apical part with a wrinkled blunt lamella (wl) covering a slender and protruding process (ds) housing the distal part of the seminal groove (g) (Figs 31, 33, 35); the latter running from the fovea (F) (Figs 31, 33–35) up to process ds. Paracoxite (Px) broad, curved mesad, emerging from a depressed coxite (Co), distal third slightly enlarged, apically narrowing into a pointed apex, directed mesad (Figs 33–35).

Arid bioclimatic zone, central Tunisia; hitherto known only from the type locality, Châambi Mountain.
