Type locality. Calabria, Vibo Valentia, Le Serre Mountains, Spadola, 790m ( Fig. 254 ).

Diagnosis. A small–medium size Solariola (TL: 2.5 8– 3.20 mm; BL: 2.15–2.75 mm) belonging to the gestroi group with more robust body shape. Within the species group, it is easily recognisable by black–darkish cuticle, the quite stubby elytra sub-parallel to sides with elytral setae elongate and raised or semi-erect. Rostrum short (RL: 0.35–0.50 mm, RW: 0.27–0.35 mm, RL/RW: 1.30–1.43). Mesorostrum carinae divergent to sides. Forehead convex and wide (FW/MW: 2.00–2.00). Submentum with yellowish, flattened, and short pappolepida. Antennae with scape and funicle elongate and thin (SL: 0.45–0.60 mm, FL: 0.70–0.80 mm, SL/FL: 0.64–0.75). Pronotum more long than wide (PL: 0.57–0.75 mm, PW: 0.52–0.70 mm, PL/PW: 1.07–1.10) without echinopappolepida at base. Elytra elon-gate–oblong (EL: 1.50–1.95 mm, EW: 0.80–1.03 mm, EL/EW: 1.87–1.90), sub-parallel to sides, dorsally vaulted with elytral setae elongate, raised or semi-erect

Holotype description. Male. See Figs 28, 28a, 28b, 28c, 28d, 28e . Quite stubby oblong body (T L: 2.65 mm, BL: 2.20 mm). Black–darkish cuticle.

Rostrum quite slender and short (RL: 0.40 mm, RW: 0.30 mm, RL/RW: 1.33), conical to sides with pterygium expanded. Epistome absent. Mesorostrum carinae divergent to sides. Submentum with some pappolepida, yellowish, short and not visible around mesorostrum. Interocular pit visible. Forehead convex and wide (FW/MW: 2.00). Vestigial eyes very convex, small but well visible.

Antennae with scape and funicle elongate and thin (SL: 0.50 mm, FL: 0.75 mm, SL/FL: 0.67); AS ratio: 6.6.4.4.3.3.3.11. Scape clubbed, more robust than funicle, curved at proximal third and progressively thickening towards apex. Funicle segments with elongate and thin setae. Club three-segmented, quite fusiform, in length twice the width, densely covered by thin setae.

Pronotum more long than wide (PL: 0.60 mm, PW: 0.55 mm, PL/PW: 1.09), wider in the middle and without echinopappolepida at base. Scutellum visible.

Elytra oblong–elongate and sub–parallell to sides, dorsally vaulted (EL: 1.60 mm, EW: 0.85 mm, EL/EW: 1.88), wider at middle with slightly convex suture. Humeri rounded. Striae with 13–14 punctures, catenulate. Interstriae slightly convex, with thin and elongate raised or semi-erect setae. Elytral declivity <60 degrees.

Legs short and robust with femora clubbed. Protibia with six acute spines on inner edge and an evident mucro on inner apical angle. Protibia slightly sinuous on inner edge and straight in side view. Metatibia and mesotibia straight in side view. All tibia with noticeable apical comb. Tarsal segment 1 short, conical; segment 2 short and transverse; segment 3 very bilobed; all segments with thin golden setae. Onychium curved, robust and short with one short claw.

Male genitalia. See Figs: dorsal shape aedeagus Fig. 74 ; apex of penis Fig. 74 ’; IX sternite Fig. 117 .

Female genitalia. See Figs: spermatheca Fig. 160 ; VIII sternite Fig. 203 .

Sexual dimorphism. Males can usually be recognized by their smaller size, slender appearance, more rounded humeri, legs stronger with a more noticeable apical mucro, and ventrites 1 and 2 slightly hollowed.

Paratypes variability. Paratypes, sexual dimorphism excluded, are similar to the holotype but differs in size.

Distribution. See Figs. 222, 222a. Italian endemic. Known from Vibo Valentia, Spadola type locality, at 750– 800 meters of elevation.

Etymology. This species is named from the Latin adjective venustus, pretty in English.

Ecology and Phenology. S. venusta specimens were collected by Winkler or Berlese extractors from soil obtained sifting the leaf litter of a grove of Oaks and Chestnut trees with Hedera sp., in springtime. Also with pitfall traps.

Main soil type. Dystrict Cambisol ( European Soil Data Centre; Panagos et al. 2012) .

Reproduction. Amphigonic.

Associated species. Sympatric with Pseudomeira paganettii (A. & F. Solari, 1907) and Aparopion suturidens Reitter, 1891 .
