Within the species group, it is recognisable by small size, elytral declivity>75 degrees, pronotum longer than wide. Rostrum robust and short (RL: 0.40–0.45 mm, RW: 0.30–0.35 mm, RL/RW: 1.29– 1.33). Mesorostrum carinae sub-parallel or slightly divergent to sides. Forehead convex (FW/MW: 2.00–2.00). Submentum with short, whitish-yellowish pappolepida. Antennae with thin scape and elongate funicle (SL: 0.45–0.50 mm, FL: 0.65–0.80 mm, SL/FL: 0.63–0.69). Pronotum longer than wide (PL: 0.55–0.75 mm, PW: 0.50–0.65 mm, PL/PW: 1.10–1.20) without echinopappolepida at base. Elongate, slightly sub-oval elytra, dorsally vaulted (EL: 1.52–1.85 mm, EW: 0.75–0.90 mm, EL/EW: 2.00–2.05) with thin, not elongate, raised setae.

Holotype description. Male. See Figs 42, 42a, 42b, 42c, 42d, 42e. Elongate body (T L: 2.50 mm, BL: 2.05 mm). Red-brownish cuticle.
Rostrum short and robust (RL: 0.40 mm, RW: 0.30 mm, RL/RW: 1.33), conical to sides with pterygium expanded. Epistome absent. Mesorostrum carinae sub-parallel to sides. Submentum with few, short and yellowish pappolepida, not visible around mesorostrum. Interocular pit visible. Forehead convex (FW/MW: 2.00). Vestigial eyes, small, slightly convex, and just visible.
Antennae thin and elongate (SL: 0.45 mm, FL: 0.65 mm, SL/FL: 0.69); AS ratio: 5.4.3.2.2.2.2.8. Scape clubbed, slightly robust than funicle, curved at proximal third and progressively thickening towards apex. Funicle elongate and thin; all segments with elongate and thin setae. Club three-segmented, oval-shaped, in length twice the width, densely covered by thin setae.
Pronotum longer than wide (PL: 0.55 mm, PW: 0.50 mm, PL/PW: 1.10), wider at middle and without echinopappolepida at base. Scutellum visible.
Elytra elongate, slightly sub-oval to sides, dorsally vaulted (EL: 1.52 mm, EW: 0.75 mm, EL/EW: 2.03), wider at middle with convex suture. Humeri rounded. Striae with 14 punctures, catenulate, close, not small, deep. Interstriae convex with thin, short, raised setae. Elytral declivity <75 degrees.
Legs elongate and not 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. 88; apex of penis Fig. 88 ’; IX sternite Fig. 131.
Female genitalia. See Figs: spermatheca Fig. 174; VIII sternite Fig. 217.
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 Mountains on the top Antennammare Mount at 1000–1133 meters of elevation.
Etymology. Named after Raffaele (Raphael in biblical Latin), the young son of one of us (Baviera).
Ecology and Phenology. Collected S. raphaelis by Winkler extractors from soil obtained sifting the leaf litter of Quercus, in winter or spring season.
Main soil type. Dystric Cambisol (European Soil Data Centre; Panagos et al. 2012).
Reproduction. Amphigonic.
Associated species. Sympatric with Pseudomeira vitalei (A. & F. Solari, 1907).
