Type locality. Sicily, Palermo, Sicani, Ficuzza Wood ( Fig. 228 ).

Diagnosis. A medium or large size Solariola (TL: 3.30– 3.30 mm; BL: 2.50– 2.50 mm) belonging to the doderoi group with quite slender body shape. Within the species group, it is easily recognizable by black-brownish cuticle, elytra and pronotum less slender and elongate. Rostrum elongate (RL: 0.55– 0.55 mm, RW: 0.40– 0.40 mm, RL/RW: 1.38–1.38). Mesorostrum carinae parallel to sides. Forehead convex (FW/MW: ratio 2.20–2.42). Submentum with sparse and elongate pappolepida. Antennae quite elongate and thin (SL: 0.65– 0.65 mm, FL: 0.95– 0.95 mm, SL/FL: 0.68–0.68). Pronotum almost as long as wide (PL: 0.75– 0.73 mm, PW: 0.70– 0.68 mm, PL/PW: 1.07–1.07) with few echinopappolepida at base. Elytra sub-oval to sides, dorsally vaulted (EL: 1.80–1.90 mm, EW: 0.95–1.00 mm, EL/EW: 1.90–1.90).

Holotype redescription. Male. See Figs 2, 2a, 2b, 2c, 2d, 2e . Stubby body ( TL: 3.30 mm and BL: 2.50 mm). Black-brownish cuticle.

Rostrum elongate (RL: 0.55 mm, RW: 0.40 mm, RL/RW: 1.38), conical to sides with expanded pterygium. Epistome absent. Mesorostrum carinae parallel to sides. Submentum covered by whitish-yellowish pappolepida, also partially visible around mesorostrum. Interocular pit visible. Forehead convex (FW/MW: ratio 2.20). Vestigial eyes flat and just visible.

Antennae thin and elongate (SL: 0.65 mm, FL: 0.95 mm, SL/FL: 0.68); AS ratio: 9.7.4.3.3.3.3.13. Scape clubbed, slightly more robust than funicle, curved at proximal third and progressively thickening towards apex. Funicle very long and thin; all antennal segments with short and thin setae. Club three-segmented, elongate-oval, in length twice the width, densely covered by thin setae.

Pronotum slightly elongate (PL: 0.75 mm, PW: 0.70 mm, PL/PW: 1.07), wider in the middle and with few echinopappolepida at base. Scutellum visible.

Elytra oblong elongate, rounded to sides, dorsally vaulted (EL: 1.80 mm, EW: 0.95 mm, EL/EW: 1.90), wider at middle with flat suture. Humeri rounded. Striae with 12–13 evident punctures, catenulate, deep. Interstriae flat with thin setae raised and quite short. Elytral declivity> 60 degrees.

Legs short and robust with femora clubbed. Protibia quite sinuous on inner edge and slightly curved in side view with six–seven acute spines on inner edge and an evident mucro on inner apical angle. 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. 48 ; apex of penis Fig. 48 ’; IX sternite Fig. 91 .

Female genitalia. See Figs: spermatheca Fig. 134 ; VIII sternite Fig. 177 .

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. 221, 221a. Sicilian endemic. Known only from Palermo, Sicani Mountains, Ficuzza forest around 900–1,000 meters of elevation.

Ecology and Phenology. Unknown. Our repeated collections at the type locality gave negative results.

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

Reproduction. Amphigonic.

Associated species. Unknown.
