( Figures 22, 22a, 22b, 22c, 22d, 22e, 22f , 42g , 81 , 120 )

Type locality. Sicily, Palermo, Sicani, Prizzi , Monte Carcaci (163).

Diagnosis. A medium-large size species (length: 3.40–4.10 mm.) with stubby body (length/width ratio: 1.50– 1.54), sub-oval elytra with dense imbricate dark brown scales here and there paler, belonging to the ficuzzensis group. Within the species group, it is recognisable by elytra less vaulted on disc, less elongate, semi-erect (45°– 60°) setae on elytral declivity and protibia curved at apex. Rostrum sub-parallel to the sides with with eyes less convex and pterygia obvious. Sizes: pronotum (length: 0.70–0.90 mm, width: 0.85–1.00 mm, ratio 0.85–1.00), elytra (length: 2.15–2.50 mm, width: 1.40–1.67 mm, ratio 1.50–1.54).

Holotype. Female. Total length: 3.75 mm. Stubby body and elytra sub-oval. Dorsal vestiture with dense imbricate dark brown scales here and there paler with metallic sheen. Rostrum clothed by golden-brown scales, transverse (length/width ratio 0.75), sub-conical to the sides. Pterygia inconspicuous. Epistome small, inconspicuous and slightly concave. Mesorostrum concave, anteriorly with twelve thin, short, erect setae. Vertex wide and convex (vertex width / mesorostrum width: ratio 1.83) with many, elongate, slightly widened apex, semierect setae. Interocular space with obvious fovea. Lateral, relatively large, quite convex eyes protruding from outline of head. Antenna robust and short with recumbent, golden/silvery, thin setae. Antenna with ratio 0.67 (scape length: 0.70 mm, funicle length: 0.90 mm). Scape clubbed more robust than funicle, curved al basal third and progressively thickening towards apex. Funicle segments including club, relative lengths as follows: 10.5.4.4.3.3.3.15; first five segments with widened setae; segments 3–7 pearl-shaped. Club twice wider than funicle, compact, fusiform with suture between first and second segment visible.

Pronotum clothed with dark brown scales here and there paler, transverse (length: 0.80 mm, width: 0.95 mm, ratio: 0.84), slightly sub-conical but sides sinuate, wider in the middle and less wide at base of its anterior margin, with short, slightly widened apex, golden semi-erect setae. Punctation usually covered by scales. Scutellum small and inconspicuous. Humeri straight.

Elytra (length: 2.35 mm, width: 1.56 mm, ratio: 1.52) slightly vaulted dorsally, sub-oval, clothed with dense imbricate dark brown scales here and there paler, rounded on sides, wider at the middle, flat suture. Elytral declivity with slim setae, slightly widened apex, semi-erect (45°–60°). Punctation of striae, shallow, rather catenulate and impressed. Interstriae with slim setae, slightly widened apex, semi-erect.

Legs short and robust clothed by golden-brown scales and with short, slightly widened apex golden setae. Femora little clubbed. Protibia with two acute spines on inner edge, curved at apex, with evident mucro on inner apical angle. Protibia quite sinuous on inner edge, metatibia and mesotibia straight in side view.

Tarsal segment 1 short, conical; segment 2 short and transverse; segment 3 shallowly bilobed; all segments with thin golden setae. Onychium curved, robust and short.

Female genitalia. See Figures: spermatheca ( Fig. 81 ), sternite VIII ( Fig. 120 ). Genitalia were examined in five specimens.

Paratype variability. All paratypes are females and differs only in size.

Other material specimens (all females) differ for shape less elongate and more erect setae (angle with elytral surface 60°–75°).

Etymology. This species named after Silvana (Maria Chemello), the wife of the first author, in appreciation of her cooperation and contribution to the field research.

Distribution. See Fig 140 . Italian endemic. Known from Sicani Mountains near type locality Prizzi.

Ecology and Phenology. Collected from Berlese or Winkler extraction of an oak forest in late spring and in early automn, sifting the compact leaf litter on calcareous soil, at 800–1000 meters. They are not evident during the hot dry summer because probably overwinter deeper in the soil.

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

Reproduction. Probably parthenogenetic. Species known from fourteen females.
