( Figures 12, 12a, 12b, 12c, 12d, 12e, 12f View FIGURES 12 – 12 , 41d View FIGURES 41 , 71 View FIGURES 60 – 98 , 110 View FIGURES 99 – 137 )

Type locality. Sicily, Palermo, Sicani, Bisacquino (Fig. 153).

Diagnosis. A medium-size species (3.40–4.00 mm) belonging to the adrianae group with short sub-parallel elytra (length/width ratio: 1.63–1.65) and body shape sub-cylindrical. Within the species group, it is recognisable by elytral declivity with raised setae (30°–45°), pronotum less transverse (length: 0.77–0.90 mm, width: 0.80–1.00 mm, ratio 0.90–0.96), mesorostrum with clavate setae and protibia with only two acute spines on inner edge. Elytra slightly vaulted dorsally (length: 2.20–2.60 mm, width: 1.35–1.58 mm, ratio 1.63–1.65), clothed by imbricate brown-silvery scales and and short silvery setae clavate.

Type series. Holotype female with the following labels: [transparent label] genitalia in DHMF // [white, printed] ♀ // [white, printed] “I, Sicilia, PA [Palermo], Sicani , Bisacquino 3, vaglio Olea , 4.IV. 2011 ” // [white, printed] “ N 37°42’25.8’’ E 013°14’40.5’’ legg GoogleMaps .

Baviera & Rando, Bellò & Chemello” (CBE); 1 female: “PA [Palermo], Sicani, Bisaquino, Quercus + Olea , N 37°41.422’ E 013°15.320’, 10/13.III. [20] ‘09, legg. Baviera & Bellò” (CBE). Types are 16 (all females).

Other material. 3 females: “Si-PA-Sicani, Chiusa Sclafani, m. 720 s.l.m., vaglio Olea e. sativa // 37°42.204’ N 013°17.240’ E, 10–13. III. (20)’09, legg. Baviera C. & Bellò C. ” ( CBE).

Holotype. Female. Total length: 3.60 mm. Body shape slender and subcylindrical. Dorsal vestiture with imbricate, brownish-silvery scales with metallic sheen; short, raised, clavate setae on pronotum as on elytra (angle with elytral surface 30°–45°).

Rostrum covered by silvery-brown scales, transverse (length/width ratio 0.69), sub-parallel to the sides. Pterygia obvious. Epistome absent. Mesorostrum slightly concave, anteriorly with about ten thin, curved, semierect setae. Vertex wide and convex (vertex width / mesorostrum width: ratio 2.00) with clavate and semi-erect or erect setae. Interocular space with fovea. Lateral and spherical eyes protruding from outline of head. Antenna robust and quite short with long, raised, silvery, widened setae. Antenna with ratio 0.75 (scape length: 0.75 mm, funicle length: 1.00 mm). Scape clubbed, slightly more robust than funicle, curved at the first third. Funicle segments including club, relative lengths as follows:; segments 1–6 with clavate-widened setae; segments 4–7 pearl-shaped. Club at least twice wider than funicle, fusiform with suture between first and second segment visible.

Pronotum clothed with silvery-brown scales, transverse (length: 0.82 mm, width: 0.90 mm, ratio: 0.91), slightly sub-hexagonal, sinuate at the sides, wider in the middle with clavate, golden silvery recumbent setae. Punctation usually covered by scales. Scutellum small but obvious.

Elytra vaulted, covered by golden silvery scales, sub-cylindrical with suture quite flat (length: 2.40 mm, width: 1.45 mm, ratio: 1.65), wider at the middle. Humeri short and rounded. Elytral declivity with raised setae (30°–45°). Punctation of striae, shallow, catenulate and impressed. Interstriae flat, with clavate, long, golden silvery, raised or semi-erect setae.

Legs short and robust covered by silvery-brown scales and rather short, clavate, silvery-golden setae. Femora clubbed. Protibia with two acute spines on inner edge, with mucro evident on inner apical angle. Protibia not 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 quite short.

Female genitalia. See Figures: spermatheca ( Fig. 71 View FIGURES 60 – 98 ), sternite VIII ( Fig. 110 View FIGURES 99 – 137 ). Genitalia were examined in six specimens.

Paratype variability. Paratypes (all females) are similar to the holotype and differs only in size.

Distribution. See Fig. 139. Italian endemic. Known from Sicani Mountains only near type locality Bisacquino.

Etymology. Named from Latin word sicelidis (Sicilian) .

Ecology and Phenology. Collected by Berlese and Winkler extractors from soil obtained sifting the leaf litter on clay soil, of an olive grove in March and April, at 700–800 meters.

Collections in the summer months gave negative results suggesting that adults of the Dodomeira sicelidis are absent during this time.

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

Reproduction. Probably parthenogenetic. Species known from eighteen females.

Chorological relationships. Sympatric with Dolichomeira sp., genus usually wintry, at Bisacquino.
