Type locality. Sicily, Catania, Erei Mountains, Caltagirone , San Cono , 450m. ( Fig. 237 ) .

Diagnosis. A large size Solariola (TL: 3.00–4.00 mm; BL: 2.55–3.40 mm) belonging to the doderoi group with quite slender body shape. Within the species group, it is easily recognisable by brownish cuticle and for the less slender body shape. Rostrum quite elongate (RL: 0.50–0.55 mm, RW: 0.35–0.40 mm, RL/RW: 1.38–1.43). Mesorostrum carinae divergent to sides. Forehead convex (FW/MW: ratio 2.20–2.42). Mesorostrum and submentum covered by yellowish, compact and elongate pappolepida. Antennae elongate and thin (SL: 0.65–0.75 mm, FL: 0.85–1.00 mm, SL/FL: 0.75–0.76). Pronotum slightly elongate (PL: 0.75–0.90 mm, PW: 0.70–0.85 mm, PL/PW: 1.06–1.07) with many echinopappolepida at base. Elytra sub-parallel to sides, dorsally vaulted (EL: 1.91–2.40 mm, EW: 1.05–1.30 mm, EL/EW: 1.82–1.85).

Antennae thin and elongate (SL: 0.65 mm, FL: 0.85 mm, SL/FL: 0.76); AS ratio: 7.7.4.3.3.3. 3.3.11. Scape clubbed, slightly more robust than funicle, curved at proximal third and progressively thickening towards apex. Funicle long and quite thin; all antennal segments with short and thin setae. Club three-segmented, compact-oval, in length twice the width, densely covered by thin setae.
