Type locality. Calabria, Catanzaro, Sambiase, Terme di Caronte, 260m ( Fig. 255 ).

Diagnosis. A small size Solariola (TL: 2.2 0–2.80 mm; BL: 1.90–2.30 mm) belonging to the gestroi group with more robust body shape. Within the species group, it is recognisable by red-brownish cuticle, the quite stubby ely- tra sub-oval to sides with elytral setae short and recumbent, more slender rostrum. Rostrum short but slender (RL: 0.40–0.50 mm, RW: 0.26–0.30 mm, RL/RW: 1.55–1.67). Mesorostrum carinae slightly divergent to sides. Forehead convex and wide (FW/MW: 2.00–2.00). Submentum with yellowish, flattened, and short pappolepida. Antennae with scape and funicle quite elongate and thin (SL: 0.55–0.60 mm, FL: 0.50–0.60 mm, SL/FL: 0.71–0.77). Pronotum sub-square or more long than wide (PL: 0.57–0.75 mm, PW: 0.52–0.70 mm, PL/PW: 1.00–1.10) without echinopappolepida at base. Elytra oval-elongate (EL: 1.40–1.70 mm, EW: 0.75–0.90 mm, EL/EW: 1.87–1.89), sub-oval to sides, dorsally vaulted with elytral setae short, recumbent.

Holotype description. Male. See Figs 29, 29a, 29b, 29c, 29d, 29e . Quite stubby oval body (T L: 2.80 mm, BL: 2.30 mm). Red-brownish cuticle.

Rostrum slender and short (RL: 0.50 mm, RW: 0.30 mm, RL/RW: 1.67), conical to sides with pterygium expanded. Epistome absent. Mesorostrum carinae slightly divergent to sides. Submentum with some pappolepida, yellowish, short and not visible around mesorostrum. Interocular pit not visible. Forehead convex and wide (FW/MW: 2.00). Vestigial eyes quite convex, small, visible.

Antennae with scape short and funicle elongate and thin (SL: 0.55 mm, FL: 0.75 mm, SL/FL: 0.73); AS ratio: 7.5.4.3.3.3.3.12. Scape clubbed, more robust than funicle, curved at proximal third and progressively thickening towards apex. Funicle segments with elongate and thin setae. Club three-segmented, quite fusiform, in length twice the width, densely covered by thin setae.

Pronotum as long as wide (PL: 0.60 mm, PW: 0.60 mm, PL/PW: 1.00), wider in the middle and without echinopappolepida at base. Scutellum visible.

Elytra oval-elongate and sub-oval to sides, dorsally vaulted (EL: 1.70 mm, EW: 0.90 mm, EL/EW: 1.89), wider at middle with slightly convex suture. Humeri rounded. Striae with 12–13 punctures, catenulate. Interstriae slightly convex, with thin, short, and recumbent setae. Elytral declivity <60 degrees.

Legs quite short and robust with femora clubbed. Protibia with six acute spines on inner edge and an evident mucro on inner apical angle. Protibia slightly 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. 75 ; apex of penis Fig. 75 ’; IX sternite Fig. 118 .

Female genitalia. See Figs: spermatheca Fig. 161 ; VIII sternite Fig. 204 .

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. 222, 222a. Italian endemic. Known from Catanzaro, Sambiase, Terme di Caronte, at 260 meters of elevation.

Etymology. This species is named after Zoia (Stefano), collector of the holotype, specialist in Coleoptera Chrysomelidae and friend of one of us (Osella).

Ecology and Phenology. Collected S. zoiai by Winkler or Berlese extractors from soil obtained sifting the leaf litter of a grove of Oaks with Hedera sp., in springtime.

Main soil type. Orthic Luvisol ( European Soil Data Centre; Panagos et al. 2012) .

Reproduction. Amphigonic.

Associated species. Sympatric with Pseudomeira lucana Bellò & Pierotti, 1992 .
