Within the species group, it is easily recognisable by black brownish cuticle and the elongate elytra with elytral punctures spaced and small. Rostrum quite elongate (RL: 0.45–0.60 mm, RW: 0.30–0.45 mm, RL/RW: 1.33–1.50). Mesorostrum carinae divergent to sides. Forehead convex (FW/MW: ratio 2.33–2.33). Submentum and laterally rostrum with thick and elongate pappolepida. Antennae elongate and thin (SL: 0.55–0.70 mm, FL: 0.80–0.95 mm, SL/FL: 0.69–0.77). Pronotum slightly elongate (PL: 0.70–0.80 mm, PW: 0.65–0.75 mm, PL/PW: 1.07–1.08) with many echinopappolepida at base. Elytra sub-parallel to sides, dorsally vaulted (EL: 1.82– 2.20 mm, EW: 0.90–1.10 mm, EL/EW: 1.99–2.02).   Type series.  Holotypemale with following labels: [genitalia in DHMF] [transparent label] / ♂[w, p] / Ita- lia, Sicilia, Enna, Agira, Riserva Naturale Orientata vallone di Piano della Corte, 567m, vaglio  Quercus[w, p] / 37°39.102’N 14°29.077’E, 27.

Onychium curved, robust and short with one short claw.  Male genitalia. See Figs: dorsal shape aedeagus Fig. 54; apex of penis Fig. 54’; IX sternite Fig. 97.  Female genitalia.See Figs: spermatheca Fig. 140; VIII sternite Fig. 183.  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.   Paratypesvariability. Paratypes, sexual dimorphism excluded, are similar to the holotypebut differ in size.   Distribution.See Figs. 221, 221a.
