Diagnosis. A small to medium size Solariola (TL: 2.1 5– 3.10 mm; BL: 1.80–2.55 mm) belonging to the paganettii group with slender body shape. Within the species group, it is recognisable by red– yellow–brownish cuticle, elongate pronotum, median lobe of aedeagus with very evident sub medial constriction. Rostrum slender and short (RL: 0.35–0.45 mm, RW: 0.20–0.30 mm, RL/RW: 1.50–1.75). Mesorostrum carinae slightly divergent to sides. Forehead convex (FW/MW: 2.00–2.00). Submentum and laterally mesorostrum with a few, short, whitishyellowish pappolepida. Antennae long and thin (SL: 0.42–0.50 mm, FL: 0.60–0.80 mm, SL/FL: 0.63–0.70). Pronotum longer than wide (PL: 0.46–0.70 mm, PW: 0.44–0.65 mm, PL/PW: 1.08–1.13) without echinopappolepida at base. Elongate, sub-parallel elytra, dorsally vaulted (EL: 1.30–1.85 mm, EW: 0.65–0.92 mm, EL/EW: 2.00–2.07) with thin and slightly elongate setae raised.

Holotype redescription. Male. See Figs 32, 32a, 32b, 32c, 32d, 32e. Elongate body (T L: 2.75 mm, BL: 2.20 mm). Red-brownish cuticle.
Rostrum slender and short (RL: 0.40 mm, RW: 0.25 mm, RL/RW: 1.60), conical to sides with pterygium expanded. Epistome absent. Mesorostrum carinae just divergent to sides. Submentum with short, whitish-yellowish pappolepida, also partially visible around mesorostrum. Interocular pit visible. Forehead convex (FW/MW: 2.00). Vestigial eyes slightly convex, visible.
Antennae thin and elongate (SL: 0.47 mm, FL: 0.70 mm, SL/FL: 0.67); AS ratio: 6.6.4.4.3.3.3.11. Scape clubbed, slightly more robust than funicle, curved at proximal third and progressively thickening towards apex. Funicle long and thin; all segments with elongate and thin setae. Club three-segmented, oval–elongate, in length twice the width, densely covered by thin setae.
Pronotum longer than wide (PL: 0.62 mm, PW: 0.55 mm, PL/PW: 1.13), wider at middle and without echinopappolepida at base. Scutellum visible.
Elytra elongate, sub-parallel to sides, dorsally vaulted (EL: 1.55 mm, EW: 0.75 mm, EL/EW: 2.07), wider at middle with convex suture. Humeri rounded. Striae with 14–15 punctures, catenulate, not deep. Interstriae flat with thin and elongate setae raised. Elytral declivity> 60 degrees.
Legs elongate and not robust with clubbed femora. Protibia with five acute spines on inner edge and an evident mucro on inner apical angle. Protibia sinuous on inner edge and curved 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. Aedeagus with evident constriction at middle.See Figs: dorsal shape aedeagus Fig. 78; apex of penis Fig. 78 ’; IX sternite Fig. 121.
Female genitalia. See Figs: spermatheca Fig. 164; VIII sternite Fig. 207.
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. 223, 223a. Sicilian endemic. Known from Peloritani Mounts and Etna volcano, mainly around Messina at 0–800 meters of elevation.
Ecology and Phenology. We collected S.vitalei by Winkler or Berlese extractors from soil obtained sifting the leaf litter of a Quercus forest with Hedera sp. on gravelly-sandy soil.
Main soil type. Dystrict Cambisol (European Soil Data Centre; Panagos et al. 2012).
Reproduction. Amphigonic.
Associated species. Sympatric with Pseudomeira vitalei (Desbrochers, 1892).
