Type locality. Sicily, Agrigento, Montallegro ( Fig. 241 ).

Diagnosis. A medium size Solariola (TL: 3.30 mm; BL: 2.65 mm) belonging to the doderoi group with quite slender body shape. Within the species group, it is easily recognisable by brown–reddish cuticle, the particularly elongate rostrum (RL: 0.55 mm, RW: 0.33 mm, RL/RW: 1.67) not much expanded in the pterygium and not visible vestigial eyes. Forehead convex (FW/MW: ratio 2.40). Submentum and mesorostrum with thick and elongate pappolepida. Antennae elongate and thin (SL: 0.65 mm, FL: 1.00 mm, SL/FL: 0.65). Pronotum (PL: 0.70 mm, PW: 0.65 mm, PL/PW: 1.08) elongate with numerous echinopappolepida at base. Elytra sub-oval to sides, dorsally vaulted (EL: 2.00 mm, EW: 1.00 mm, EL/EW: 2.00).

Type series. Holotype male with following labels: [genitalia in DHMF] [transparent label] / ♂ [w, p] / Sicilia, Montallegro, sotto Scilla sp., 5. 1. 1994, leg.

Protibia quite 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.
