Type locality. Calabria, Reggio Calabria, Aspromonte Mountains (Fig. 256) .

Diagnosis. A small size Solariola (TL: 2.7 0–2.77 mm; BL: 2.25–2.28 mm) belonging to the paganettii group with slender body shape. Within the species group, it is recognizable by red– yellow–brownish cuticle, elongate pronotum, dentate or sub-dentate profemora. Rostrum quite slender and short (RL: 0.35–0.40 mm, RW: 0.28–0.30 mm, RL/RW: 1.25–1.33). Mesorostrum carinae divergent to sides. Forehead convex (FW/MW: 2.00–2.00). Submentum and laterally mesorostrum with a few, short, whitish-yellowish pappolepida. Antennae very long and thin (SL: 0.50–0.55 mm, FL: 0.70–0.78 mm, SL/FL: 0.70–0.71). Pronotum longer than wide (PL: 0.60–0.62 mm, PW: 0.52–0.55 mm, PL/PW: 1.13–1.15) without echinopappolepida at base. Elongate, sub-parallel elytra, dorsally vault- ed (EL: 1.65– 1.62 mm, EW: 0.79–0.82 mm, EL/EW: 2.01–2.05) with thin and elongate setae raised.

Neotype redescription. Male. See Figs 30, 30a, 30b, 30c, 30d, 30e. Elongate body (T L: 2.77 mm, BL: 2.25 mm). Yellow–brownish cuticle.

Rostrum short (RL: 0.40 mm, RW: 0.30 mm, RL/RW: 1.33), conical to sides with pterygium expanded. Epistome absent. Mesorostrum carinae just 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 flat and just visible.

Antennae thin and elongate (SL: 0.55 mm, FL: 0.78 mm, SL/FL: 0.70); AS ratio: 6.6.4.3.3.3.3.12. 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, in length twice the width, densely covered by thin setae.

Pronotum longer than wide (PL: 0.62 mm, PW: 0.55 mm, PL/PW: 1.13), wider in the basal half and without echinopappolepida at base. Scutellum visible.

Elytra elongate, sub-parallel to sides, dorsally vaulted (EL: 1.62 mm, EW: 0.79 mm, EL/EW: 2.05), wider in the basal third with convex suture. Humeri rounded. Striae with 18–19 punctures, catenulate, not deep. Interstriae flat with thin and elongate setae raised. Elytral declivity> 60 degrees.

Legs elongate and not robust with femora dentate or sub–dentate. Protibia with five acute spines on inner edge and an evident mucro on inner apical angle. Protibia sinuous on inner edge and 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. 76; apex of penis Fig. 76 ’; IX sternite Fig. 119.

Female genitalia. See Figs: spermatheca Fig. 162; VIII sternite Fig. 205.

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. Italian endemic. Known only from the southern part of Aspromonte Massif, surroundings of Gambarie at 600–1600 meters of elevation.

Ecology and Phenology. Paganetti-Hummler collected the type series under deep layers of moist beech leaves in Aspromonte (Calabria) between June and July 1895 (Flach, 1905). Although Flach (1905) write: “Bei St. Eufemia d‘Aspromonte (1600 m) fing derselbe unter denselben Verhältnissen im Kastanienwalde eine Anzahl Gestroi und wenige Paganettii”. We collected S. paganettii by Winkler or Berlese extractors from soil obtained sifting the leaf litter of a Fagus and Castanea forest with Hedera sp. Also with pitfall traps (Angelini & Sabella) or under stone and tearing clods of grass.

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

Reproduction. Amphigonic.

Associated species. Sympatric with Heteromeira marianii (Pesarini, 1972) .
