Figs 98‒107View FIGURES 98–107, 113‒117View 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 101View FIGURES 98–107, 115View FIGURES 108–117), females by the oval epigynal fovea, much more elongated than in the related H. signifer  and H. pseudosignifer  ( Figs 105View FIGURES 98–107, 116View 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 100‒104View FIGURES 98–107, 113‒115View FIGURES 108–117): Tibial apophysis as long as the tibia’s diameter, with nearly symmetric margins, with obtuse tip ( Figs 100View FIGURES 98–107, 114View 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 101View FIGURES 98–107, 115View FIGURES 108–117).

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