Type locality. Sicily, Palermo, Monte Pellegrino (Fig. 157).

Diagnosis. A small or medium-sized Dodomeira (2.90–3.90 mm) belonging to the exigua group with more stubby body and oval-elongate elytra on males (length/width ratio: 1.57–1.58), less on females (length/width ratio: 1.60–1.65). Within the species group, it is easily recognisable by the elytral declivity with more elongate and raised setae (30°–45°). Apex of penis sub-triangular and quite sharp. Sizes: pronotum (length: 0.65–0.85 mm, width: 0.75–0.95 mm, ratio 0.86–0.94), elytra (length: 1.90–2.40 mm, width: 1.20–1.45 mm, ratio 1.57–1.65).

Material examined. Lectotypus with the following labels: [white, handwritten] Sicilien // [white, printed] coll. Stierlin // [red, printed] Syntypus // [white, printed] ♂ // [red, handwritten and printed] // Pseudomeira exigua (Stierlin) , Lectotypus det. Pierotti ( SDEI). Two Paralectotypus (both on a pin) with the following labels: [white, printed] Sicilia // [white, printed] coll. Stierlin // [red, printed] Syntypus // [white, printed] ♂ //[red, handwritten and printed] // Pseudomeira exigua (Stierlin) , Paralectotypus det. Pierotti (SDEI).

Other material: we have examined 188 males and females specimens (ADE, APA, CBA, CBE, ECO, GOS, HPI, LCO, LDI, LFO, MTE, MCIZ, MCZR, MSNG, MSNM, MSNV, MZUB, MZUF, PMA, RBO, SDEI).

Redescription. Male Figs. 16, 16a View FIGURES 16 – 16 . Total length: 3.60 mm. Stubby body. Elytra oval-elongate. Dorsal vestiture with imbricate, golden-brown scales with metallic sheen.

Rostrum covered by golden-brown scales, very transverse (length/width ratio 0.60), quite conical to the sides. Pterygia inconspicuous. Epistome present, inconspicuous, concave. Mesorostrum concave, anteriorly with ten/ twelve thin, curved, semi-erect setae. Vertex wide and convex (vertex width / mesorostrum width: ratio 2.00) with several, elongate, widened/clavate, raised setae. Interocular space without visible fovea.

Lateral, large, slightly spherical eyes barely protruding from outline of head. Antenna quite robust and short with recumbent, golden, widened setae. Antenna with ratio 0.79 (scape length: 0.75 mm, funicle length: 0.95 mm). Scape clubbed, slightly more robust than funicle, curved at the basal third and progressively thickening towards apex. Funicle segments including club, relative lengths as follows: 10.5.4.3.3.3.3.12; first five segments with widened setae; segments 3–7 pearl-shaped. Club at least twice wider than funicle, short, fusiform with suture between first and second segment visible.

Pronotum clothed with golden-brown scales, quite sub-square (length: 0.90 mm, width: 0.95 mm, ratio: 0.94), slightly sub-conical, rounded at the sides, wider in the middle, with short, widened-clavate, golden raised setae. Punctation usually covered by scales. Scutellum inconspicuous.

Elytra (length: 2.20 mm, width: 1.40 mm, ratio: 1.57) vaulted dorsally, sub-oval, covered by golden-brown scales, with flat suture, strongly rounded on sides, wider at the middle. Humeri long rounded. Elytral declivity with widened-clavate and raised setae (30°–45°). Punctation of striae, shallow, rather catenulate and impressed. Interstriae flat, with widened-clavate, elongate, golden, raised setae.

Legs short and robust clothed by golden-brown scales and rather short, widened golden setae. Femora little clubbed. Protibia with two-three acute spines on inner edge, 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.

Male genitalia. See Figures: dorsal shape aedeagus ( Fig. 45 View FIGURES 45 – 59 ), internal sac ( Fig. 50 View FIGURES 45 – 59 ), sternite IX ( Fig. 55 View FIGURES 45 – 59 ), apex of penis ( Fig. 16f View FIGURES 16 – 16 ).

Genitalia were examined in twelve specimens.

Distribution. See Fig. 140 View FIGURE 140 . Italian endemic. Known only from the type locality “Pellegrino Mount” at 400– 500 meters.

Ecology and Phenology. Collected by Berlese and Winkler extractors from soil obtained sifting the leaf litter under Rubus sp. on a pasture in spring and automn, at 400–500 meters.

Collections in the summer season gave negative results.

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

Reproduction. Amphigonic.

Chorological relationships. Sympatric with D. pfisteri ( Stierlin, 1864) , Pseudomeira erinacea Bellò & Baviera (2011) , Dolichomeira microphtalma ( Seidlitz, 1868) and Typhloreicheia praecox (Schaum, 1857) .
