( Figures 27, 27a, 27b, 27c, 27d, 27e, 27f View FIGURES 27 – 27 , 43d View FIGURES 43 , 86 View FIGURES 60 – 98 , 125 View FIGURES 99 – 137 )

Type locality. Sicily, Palermo, Madonie, Piano Zucchi ( Fig. 167).

Diagnosis. A medium-sized Dodomeira (3.50–4.25 mm) belonging to the pfisteri group with slender body (length/width ratio: 1.70–1.80) and cylindrical elytra shape. Within the species group, it is recognisable by elongate elytra, pronotum with middle band of clearer scales, elytral declivity with quite spatulate raised setae (30°–45°) and protibia with four acute spines on inner edge. Sizes: pronotum (length: 0.75–0.90 mm, width: 0.75–1.00 mm, ratio 0.90–1.00), elytra (length: 2.30–2.80 mm, width: 1.35–1.45 mm, ratio 1.70–1.80).

Type series. Holotype female with the following labels: [transparent label] genitalia in DHMF // [white, printed] ♀ // [white, printed] “I, Sicilia, PA[Palermo], Madonie, Piano Zucchi, m 1100, 17.IV.2010, legg.

Bellò & Chemello” ( CBE). Types are 19 (all females).

Holotype. Female. Total length: 4.10 mm. Slender body with elytra elongate-cylindrical. Dorsal vestiture with very imbricate, golden-brown scales with metallic sheen.

Rostrum covered by golden-brown scales, transverse (length/width ratio 0.75), conical to the sides. Pterygia barely protruding from the rostrum. Epistome absent. Mesorostrum slightly concave, anteriorly with twelve thin, curved, semi-erect setae. Vertex quite wide and convex (vertex width / mesorostrum width: ratio 1.77) with several, elongate, clavate, raised setae. Interocular space without visible fovea.

Lateral, quite small, slightly convex eyes barely protruding from outline of head. Antenna quite robust and short with recumbent, golden-silvery, widened setae. Antenna with ratio 0.73 (scape length: 0.80 mm, funicle length: 1.10 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:; first six segments with widened setae silvery; segments 3–7 pearl-shaped. Club at least twice wider than funicle, elongate, fusiform with suture between first and second segment visible.

Pronotum clothed with golden-brown scales with middle band of clearer scales, quite sub-square (length: 0.90 mm, width: 1.00 mm, ratio: 0.90), slightly sub-conical, slightly sinuate to the sides, wider in the middle, with short, clavate, golden raised setae. Punctation usually covered by scales. Scutellum inconspicuous.

Elytra (length: 2.65 mm, width: 1.50 mm, ratio: 1.77) vaulted dorsally, cylindrical, covered by golden-brown scales, with flat suture, wider at the middle. Elytral declivity with quite spatulate and raised setae (30°–45°). Punctation of striae, shallow, rather catenulate and impressed. Interstriae flat, with clavate, elongate, golden, raised setae. Humeri short and rounded.

Legs short and robust clothed by golden-brown scales and rather short, widened golden setae. Femora little clubbed. Protibia with four acute spines on inner edge, with evidentevident 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. 86 View FIGURES 60 – 98 ), sternite VIII ( Fig. 125 View FIGURES 99 – 137 ). Genitalia were examined in six specimens.

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

Distribution. See Fig. 141. Italian endemic. Known only from the type locality “Piano Zucchi” at 1100 meters a.s.l. in Madonie Mountains.

Etymology. This species named after Angela (Rando Baviera), in appreciation of her cooperation and contribution to the field research.

Ecology and Phenology. Collected in an old forest of Quercus ilex L. in April and June sifting the leaf litter on calcareous soil. Collections in the summer months gave negative results suggesting that adults aestivate and reappear, less common, in autumn.

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

Reproduction. Probably parthenogenetic. Species known from 18 females.

Chorological relationships. Sympatric with Acallorneuma sp..
