Description.

Male (Algeria-Morocco, MR012, MR): Carapace with band of white setae around margin of thoracic region and scattered patches elsewhere; cephalic region subtriangular, longer than wide, strongly raised with rounded posterior margin overhanging thoracic region; AME distinctly smaller than PME (AME/PME 0.48), median eyes slightly overlapping on horizontal and vertical axes, PME somewhat sunken into carapace; ALE tubercles present; PER slightly narrower than AER (PER/AER 0.88), PLE position on carapace 0.35; clypeal hood forms acute angle; fovea indistinct. Chelicerae contiguous mesally, with lateral boss. Legs with bands of white setae; with row of distal ventral macrosetae on metatarsus I–IV and scattered short ventral macrosetae on tibia, metatarsus and tarsus I–IV. Abdomen dark gray, nearly encircled by a band of white setae, with numerous patches of white setae dorsally, especially around sigilla (Figs 8A, B, 19 A–D).

Male palp with proximal-distal axis, tegulum moderately elongate, subtrapezoidal; second loop of sperm duct curves proximally away from then back to distal margin of tegulum in retrolateral view (Figs 12B, 19J); conductor and embolus together form apical complex making one helical turn; conductor tapers to point; tegular division longer than embolic division; cymbium with one retrolateral and several prolateral macrosetae (Figs 12 A–C, 19I, J, 20 A–F).

Female (Wadi Mashash, Israel, MR013, HUJ): Carapace with scattered white setae; cephalic region subtriangular, longer than wide, so strongly raised as to be nearly vertical (Figs 1A, 19H); AME distinctly smaller than PME (AME/PME 0.37), median eyes slightly overlapping on horizontal and vertical axes; PME somewhat sunken into carapace; ALE tubercles indistinct; PER slightly narrower than AER (PER/AER 0.82), PLE position on carapace 0.39; clypeal hood forms acute angle; fovea indistinct (Figs 8C, D, 19E-H, 21A, B, E). Chelicerae contiguous mesally, boss present (Figs 19G, 21C, D). Legs with row of distal ventral macrosetae on metatarsus I–IV and scattered short ventral macrosetae on tibia, metatarsus and tarsus I–IV. Abdomen with numerous patches of white setae dorsally, especially around sigilla (Figs 1A, 19E).

Epigynum with slightly converging slit-like atria occupying nearly the total length, anterior-lateral margin a curved ridge (Figs 16A, 22A). Vulva with spermathecal heads set anterior-mesally on curved stalks leading to multilobed spermathecae that diverge posteriorly (Figs 16D, 22 B–D).

Spinneret spigot morphology

(Mehav Am village, Israel, MR003, MR, and Algeria-Morocco, MR012, MR). Female ALS with at least 5 MAP, at least 1 within and at least 4 on mesal edge of spinning field, with at least 40 PI (Fig. 23A, B); male with fewer PI (Fig. 24B). Female PMS with 2 anterior mAP, posterior field of 21 spigots that vary in size and shape (Fig. 23C); male with only 7 posterior spigots, suggesting that female may have both AC and CY spigots (Fig. 24C). Male PLS with basal MS apparently unaccompanied by flanking AC, distal field of 15 AC (Fig. 24D, F; our female preparation inadequate to view spigots). Male cribellar plate with no sign of spigots (Fig. 25B, C); epiandrous gland spigots present (Fig. 22E, F).
