Type locality. Calabria, Reggio Calabria, Aspromonte Mountains, Gerace, Contrada Puzzello, 205m (Fig. 248) .

Diagnosis. A medium–large size Solariola (TL: 2.7 5– 3.60 mm; BL: 2.30–3.00 mm) belonging to the gestroi group with more robust body shape. Within the species group, it is recognisable by brownish–reddish cuticle; elytra sub-oval to sides, pronotum as long as wide, legs thin and elongate. Rostrum quite short (RL: 0.45–0.55 mm, RW: 0.30–0.40 mm, RL/RW: 1.38–1.50). Mesorostrum carinae slightly divergent to sides. Forehead convex and wide (FW/MW: 2.00–2.00). Submentum with whitish-yellowish, flattened, and short pappolepida. Antennae with scape and funicle elongate and thin (SL: 0.60–0.70 mm, FL: 0.75–0.95 mm, SL/FL: 0.74–0.80). Pronotum sub-square (PL: 0.65–0.85 mm, PW: 0.65–0.85 mm, PL/PW: 1.00–1.00) without echinopappolepida at base. Slightly elongate elytra, dorsally vaulted (EL: 1.70–2.20 mm, EW: 0.90–1.16 mm, EL/EW: 1.84–1.90) with elytral setae raised and quite elongate.

Holotype description. Male. See Figs 22, 22a, 22b, 22c, 22d, 22e. Slightly oval-elongate body (T L: 3.20 mm, BL: 2.60 mm). Brownish–reddish cuticle.

Rostrum short (RL: 0.50 mm, RW: 0.35 mm, RL/RW: 1.43), conical to sides with pterygium very expanded. Epistome absent. Mesorostrum carinae slightly divergent to sides. Submentum with some pappolepida, whitishyellowish and short not visible around mesorostrum. Interocular pit visible. Forehead convex and wide (FW/MW: 2.00). Vestigial eyes convex, very small but visible.

Antennae with scape and funicle elongate and thin (SL: 0.65 mm, FL: 0.85 mm, SL/FL: 0.76); AS ratio: 8.7.4.4.3.3.3.14. 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, fusiform, in length twice the width, densely covered by thin setae.

Pronotum sub-square (PL: 0.75 mm, PW: 0.75 mm, PL/PW: 1.00), wider in the middle and without echinopappolepida at base. Scutellum visible.

Elytra oval-elongate and sub-parallel to sides, dorsally vaulted (EL: 1.90 mm, EW: 1.03 mm, EL/EW: 1.84), wider in the basal third with slightly convex suture. Humeri rounded. Striae with 13–14 large punctures, catenulate. Interstriae slightly convex, with thin and elongate setae raised. Elytral declivity <60 degrees.

Legs elongate and not robust with femora clubbed. Protibia with eight acute spines on inner edge and an evident mucro on inner apical angle. Protibia slightly 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. 68; apex of penis Fig. 68 ’; IX sternite Fig. 111.

Female genitalia. See Figs: spermatheca Fig. 154; VIII sternite Fig. 197.

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 only from Aspromonte, Gerace, and Contrada Puzzello locality at 200 meters of elevation.

Etymology. This species is named after our friend and colleague Fancello (Luca), Sardinian painter and specialist in soil beetles, in appreciation and gratitude for his cooperation in our study on Peritelini .
