Submentum and laterally mesorostrum with a few, short, whitish-yellowish pappolepida. Antennae long and thin (SL: 0.50–0.55 mm , FL: 0.67–0.70 mm , SL/FL: 0.75–0.78). Pronotum longer than wide (PL: 0.60–0.70 mm , PW: 0.55–0.65 mm , PL/PW: 1.08–1.09) without echinopappolepida at base. Elongate, oblong or sub-parallel elytra, dorsally vaulted (EL: 1.65–1.90 mm , EW: 0.82–0.92 mm , EL/EW: 2.00–2.06) with thin and elongate setae raised. Material examined.

Rostrum slender and elongate (RL: 0.45 mm , RW: 0.27 mm , RL/RW: 1.67), conical to sides with pterygium expanded. Epistome absent. Mesorostrum carinae divergent to sides. Submentum with short, whitish-yellowish pappolepida, also partially visible around mesorostrum. Interocular pit visible. Forehead convex (FW/MW: 2.00). Vestigial eyes convex, visible. Antennae thin and elongate (SL: 0.55 mm , FL: 0.70 mm , SL/FL: 0.78); AS ratio: 6.6.3.3.3.3.3.12. Scape clubbed, slightly more robust than funicle, curved at proximal third and progressively thickening towards apex. Funicle long and thin; all segments with elongate and thin setae. Club three-segmented, oval–elongate, less than twice long its width, densely covered by thin setae. Pronotum longer than wide (PL: 0.65 mm , PW: 0.60 mm , PL/PW: 1.08), wider at middle and without echinopappolepida at base. Scutellum visible. Elytra elongate, oblong to sides, dorsally vaulted (EL: 1.70 mm , EW: 0.85 mm , EL/EW: 2.00), wider at middle with convex suture. Humeri rounded. Striae with 15–16 punctures, catenulate, deep. Interstriae a little convex with thin and elongate setae raised. Elytral declivity> 60 degrees. Legs short and robust with clubbed femora. Protibia with seven acute spines on inner edge and an evident mucro on inner apical angle. Protibia 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. 79 ; apex of penis Fig. 79 ’; IX sternite Fig. 122 . Female genitalia. See Figs: spermatheca Fig. 165 ; VIII sternite Fig. 208 . 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. 223, 223a. Sicilian endemic. Known from Peloritani Mounts, mainly Malabotta Forest at 1000–1300 meters of elevation. Ecology and Phenology. Osella et al. (2004 , sub S. vitalei ) consider this species a typical humid and sub-humid Mediterranean forest dweller, thus a relict species related to paleoclimate characteristic of the tertiary Mediterranean forests. Adults of S. pesarinii have been sifted from the soil or, in number, hand collected under stones in April, of an old Quercus forest growing on a moist limestonesoil. Main soil type . Dystrict Cambisol ( European Soil Data Centre ; Panagos et al . 2012 ) . Reproduction. Amphigonic. Associated species. Sympatric with Pseudomeira erinacea Bellò & Baviera (2011) and Simo grandis (Desbrochers, 1888) .
