Type locality. Sicily, Catania, Etna, Linguaglossa, Piano Porcaria, 1110m ( Fig. 231 ).

Diagnosis. A large size Solariola (TL: 3.40–3.80 mm; BL: 2.70–3.10 mm) belonging to the doderoi group with slender body shape. Within the species group, it is easily recognisable by depigmented and little sclerified cuticle, particularly elongate elytra with flattened-recumbent setae, and particularly shallow punctures. Rostrum elongate (RL: 0.55–0.60 mm, RW: 0.40– 0.40 mm, RL/RW: 1.38–1.50). Mesorostrum carinae sub-parallel to sides. Forehead convex (FW/MW: ratio 2.28–2.30). Submentum and mesorostrum with thick and flattened pappolepida. Antennae elongate and thin (SL: 0.65–0.70 mm, FL: 0.95–1.00 mm, SL/FL: 0.68–0.70). Pronotum slightly elongate (PL: 0.805– 0.80 mm, PW: 0.70– 0.70 mm, PL/PW: 1.14–1.14) with many echinopappolepida at base. Elytra parallel to sides, dorsally quite flattened (EL: 2.20–2.25 mm, EW: 1.05– 1.05 mm, EL/EW: 2.10–2.15).

Holotype description. Male. See Figs 5, 5a, 5b, 5c, 5d, 5e . Body shape elongate and subcylindrical ( TL: 3.80 mm and BL: 3.10 mm). Depigmented and little sclerified cuticle.

Rostrum elongate (RL: 0.60 mm, RW: 0.40 mm, RL/RW: 1.50), conical to sides with expanded pterygium. Epistome absent. Mesorostrum carinae sub-parallel to sides. Submentum covered by whitish-yellowish pappolepida, also visible around mesorostrum. Interocular pit visible. Forehead convex (FW/MW: ratio 2.30). Vestigial eyes flat and just visible.

Antennae quite thin and elongate (SL: 0.70 mm, FL: 1.00 mm, SL/FL: 0.70); AS ratio: 10.10.6.4.3.3.3.11. Scape clubbed, slightly more robust than funicle, curved at proximal third and progressively thickening towards apex. Funicle long and thin; all antennal segments with elogated and thin setae. Club three-segmented, elongateoval, in length twice the width, densely covered by thin setae.

Pronotum elongate (PL: 0.80 mm, PW: 0.70 mm, PL/PW: 1.14), wider in the middle and with many echinopappolepida at base. Scutellum visible.

Particularly elongate and parallel to sides elytra, dorsally quite flattened (EL: 2.25 mm, EW: 1.05 mm, EL/EW: 2.15), wider in the middle with flattened suture. Humeri rounded. Striae with 13–14 very shallow punctures, catenulate. Interstriae convex with short and flattened-recumbent setae. Elytral declivity>60 degrees.

Legs quite slim and elongate with femora little clubbed. Protibia with six–seven spines on inner edge and a 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. 51 ; apex of penis Fig. 51 ’; IX sternite Fig. 94 .

Female genitalia. See Figs: spermatheca Fig. 137 ; VIII sternite Fig. 180 .

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 from Linguaglossa locality in Etna volcano, at 1100 meters of elevation.

Etymology. Named after Bucolo family (Elisa and Carmelo), speleologists and passionate researchers of cave fauna, in appreciation for their availability and valuable collaboration.

Ecology and Phenology. At sight, at entrance to the cave in a sandy soil. “Raccolti a vista all’ingresso della grotta in uno dei tratti più sabbiosi” (Bucolo and Musumeci in litteris).

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

Reproduction. Amphigonic.

Associated species. Sympatric with Duvalius hartigi Magrini, Baviera & Vigna Taglianti, 2006 , Laemostenus (Pristonychus) algerinus (Gory, 1833) , Calathus (Calathus) montivagus Dejan (1831) , Tarphius gibbulus Erichson 1845 and Cryptophagus dentatus (Herbst, 1793) .
