Clypeus with a rectangular beige area ( Fig. 9), chelicerae brown with black spots. Sternum whitish with dots and brown patches at the margin.

Scale line = 0.1 mm. tions at femora, threefold annulations at tibiae and single, weak annulations at metatarsi. Opisthosoma densely covered with whitish pubescence, interspersed with dark setulae. Dorsum grey with conspicuous black cardiac mark, flanks darkish, in posterior half with four to five chevrons and two lateral dark patches. Venter greyish marbled.  Pedipalp( Figs 1, 29-30). Patellar apophysis relatively short, less than two thirds the length of tibia, in ventral view narrow, in lateral view triangular, with small but distinct bulge at basis of ventral margin. Tibia with broad, rounded RTA. Cymbial tip short, less than one fifth of CyL, broadly rounded. Cymbium length (CyL) 0.68-0.74, width (CyW) 0.38-0.44, ratio CyL/cephalothorax width 0.44-0.46. Subtegulum visible in ventral view. PTA a small narrow hook, directed retrolaterally, its tip pointing in ventral direction. Sperm duct forming an elongate, asymmetric loop in retrolateral half of tegulum, opening in 8:30 o’clock position. Conductor partly hidden behind embolus, in ventral view visible at retrolateral side of embolus. Embolus clearly divided in basal and distal embolus. Basal embolus with prolateral-distal bulge and curved keel at ventral side. Distal embolus stout, curved to retrolateral side.  Epigyne-vulva( Figs 31-32). Epigyne wider than long. Median septum almost quadrangular, epigynal sutures short. Epigynal grooves covered by lateral plates. Posterior guide pockets small, anterior guide pockets prominent, heavily sclerotized, with almost parallel slits, extending anteriorly far beyond receptacula. Receptacula at epigastric furrow, separated from each other by their diameter. Glandular heads in innerdistal position, with short ducts pointing in lateral-distal direction.    Remarks.Due to the serious illness of Dr Gershom Levy I failed to receive the typeseries of  Ebo eremusLevyfrom the Hebrew University of Jerusalemfor examination. However, the species was sufficiently characterized by Levy (1999, 2007) to propose synonymy with  Halodromus patellaris(Wunderlich).    Distributionand habitat.The species is known from the eastern Canary Islands Fuerteventura ( Wunderlich 1987, 1992) and Lanzarote, from the Negev desert in southern Israel( Levy 1999, 2007), and from Tunisia( Fig. 37). All specimens from Israelwere taken using pitfall traps. The specimens from Tunisiawere beaten from prostrate halophytic shrubs in saline habitats at both coastal and inland sites. They were perfectly camouflaged in the dense vegetation. 2611466310 17 64 2611466306 2007-04-26 C.
