Figs 98‒107 View FIGURES 98–107 , 113‒117 View FIGURES 108–117 , map 3

Types: Holotype ♂, 3♂ 3♀ paratypes from Tunisia, Kebili, Nefzaoua (N33°23’0” E7°48’0”), Vibert leg., Coll. Simon 12687 (MNHN AR15685); deposited in MNHN.

Etymology. The species name refers to the oval form of the epigynal fovea.

Diagnosis. Males of H. ovatus sp. n. differ from other species by the sickle-shaped embolic apophysis in the male ( Figs 101 View FIGURES 98–107 , 115 View FIGURES 108–117 ), females by the oval epigynal fovea, much more elongated than in the related H. signifer and H. pseudosignifer ( Figs 105 View FIGURES 98–107 , 116 View FIGURES 108–117 ).

Description. Measurements: Male (n=4): Total length 6.2‒8.0; carapace 2.66‒3.44 long, 2.22‒2.44 wide. Female (n=3): Total length 6.8‒8.8 carapace 2.16‒3.14 long, 2.08‒2.36 wide. Colour: Carapace yellowish brown, eye region infuscate; chelicerae, labium and maxillae dark reddish brown; sternum orange brown with darker margins; legs yellowish brown; abdomen pale grey. Spinulation: General pattern, with metatarsi I spineless in all specimens examined and metatarsi II spineless in 1 female.

Male palp ( Figs 100‒104 View FIGURES 98–107 , 113‒115 View FIGURES 108–117 ): Tibial apophysis as long as the tibia’s diameter, with nearly symmetric margins, with obtuse tip ( Figs 100 View FIGURES 98–107 , 114 View FIGURES 108–117 ); embolic apophysis with nearly straight retrolateral margin and strongly curved prolateral margin, at its base half as wide as in the middle, with subterminal prolateral angularity, terminally pointed ( Figs 101 View FIGURES 98–107 , 115 View FIGURES 108–117 ).

Epigyne ( Figs 105‒106 View FIGURES 98–107 , 116‒117 View FIGURES 108–117 ): Hood much wider than fovea, weekly sclerotized, with protruding median margin; pro-fovea narrow; fovea oval ( Figs 105 View FIGURES 98–107 , 116 View FIGURES 108–117 ), basal margin with an angularity; lateral pockets elongated, at its base with supplementary pocket ( Figs 106 View FIGURES 98–107 , 117 View FIGURES 108–117 ).

Ecology. The species was captured in chotts (inland salt marshes) and in a dry river bed in the semi-arid and arid climate zones of the Maghreb.

Distribution. The species is known from two localities in the Nord East of Algeria, and two localities in central and southern Tunisia (map 3).
