Type locality. Sicily, Messina, Peloritani Mountains , Castanea, Contrada Grazia ( Fig. 261 View FIGURES 259–262 ).

Diagnosis. A small to medium size Solariola (TL: 2.5 0–3.30 mm; BL: 2.05–2.70 mm) belonging to the paganettii group with slender body shape. Within the species group, it is recognisable by reddish-brownish cuticle, elytra oblong to sides with small and shallow punctures. Rostrum short and more robust (RL: 0.35–0.50 mm, RW: 0.28–0.38 mm, RL/RW: 1.28–1.33). Mesorostrum carinae slightly divergent to sides. Forehead convex (FW/MW: 2.00–2.00). Submentum and laterally mesorostrum with a few, short, whitish-yellowish pappolepida. Antennae long and thin (SL: 0.40–0.60 mm, FL: 0.60–0.80 mm, SL/FL: 0.67–0.77). Pronotum longer than wide (PL: 0.55–0.75 mm, PW: 0.50–0.70 mm, PL/PW: 1.08–1.10) without echinopappolepida at base. Elongate, sub-oval elytra, dorsally vaulted (EL: 1.50–2.00 mm, EW: 0.75–0.95 mm, EL/EW: 2.00–2.10) with thin, slightly elongate, semi-erect setae.

Holotype description. Male. See Figs 35, 35a, 35b, 35c, 35d, 35e View FIGURES 35–35 . Elongate body (T L: 2.60 mm, BL: 2.15 mm). Reddish-brownish cuticle.

Rostrum short and more robust (RL: 0.40 mm, RW: 0.30 mm, RL/RW: 1.33), conical to sides with pterygium very expanded. Epistome absent. Mesorostrum carinae divergent to sides. Submentum with short and whitish-yellowish pappolepida, also visible around mesorostrum. Interocular pit visible. Forehead convex (FW/MW: 2.00). Vestigial eyes convex, visible.

Antennae quite thin and elongate (SL: 0.50 mm, FL: 0.65 mm, SL/FL: 0.77); AS ratio: 5.5.4.3.3.2.2.12. Scape clubbed, slightly more robust than funicle, curved at proximal third and progressively thickening towards apex. Funicle quite 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: 0.60 mm, PW: 0.55 mm, PL/PW: 1.09), wider at middle and without echinopappolepida at base. Scutellum visible.

Elytra elongate, sub-oval to sides, dorsally vaulted (EL: 1.60 mm, EW: 0.78 mm, EL/EW: 2.05), wider at middle with convex suture. Humeri rounded. Striae with 14 punctures, catenulate, small and not deep. Interstriae not convex with thin, slightly elongate, semi-erect setae. Elytral declivity <60 degrees.

Legs elongate and slender with clubbed femora. Protibia with seven acute spines on inner edge and an evident mucro on inner apical angle. Protibia sinuous on inner edge and slightly 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. See Figs: dorsal shape aedeagus Fig. 81 View FIGURES 47–89 ; apex of penis Fig. 81 View FIGURES 47–89 ’; IX sternite Fig. 124 View FIGURES 90–132 . Female genitalia. See Figs: spermatheca Fig. 167 View FIGURES 133–175 ; VIII sternite Fig. 210 View FIGURES 176–218 . 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, only of type locality “Contrada Grazia” of Castanea at 350–450 meters of elevation. Etymology. Named from the type locality [Contrada] Grazia. Ecology and Phenology.
