( Figures 34, 34a, 34b, 34c, 34d, 34e, 34f View FIGURES 34 – 34 , 44c View FIGURES 44 , 93 View FIGURES 60 – 98 , 132 View FIGURES 99 – 137 )

Type locality. Sicily, Palermo, Madonie, Pizzo Carbonara (Fig. 173).

Diagnosis. A small-sized Dodomeira (3.50–3.80 mm) belonging to the pfisteri group with slender body (length/width ratio: 1.70–1.72) and cylindrical elytra shape. Within the species group, it is recognisable by elytra elongate, elytral declivity with clavate raised setae (30°–45°), rostrum transverse with length/width ratio 0.60, and protibia with two acute spines on inner edge. Sizes: pronotum (length: 0.80–0.90 mm, width: 0.90–0.95 mm, ratio 0.89–0.95), elytra (length: 2.30–2.50 mm, width: 1.35–1.45mm, ratio 1.70–1.72).

Type series. Holotype female with the following labels: [transparent label] genitalia in DHMF // [white, printed] ♀ // [white, printed] “I, Sicilia, Palermo, Madonie, Pizzo Carbonara, 1500–1750m, vaglio Fagus , 20.VII.2016, Baviera leg.” // [green, printed] “Collezione Cesare Bellò” // [red, printed] “ Dodomeira montivaga sp. n., Holotype, det. Bellò 2016 ” ( CBE).

Paratypes. 3 females: “Sicilia, Palermo, Madonie, Pizzo Carbonara, 1750m, vaglio Fagus & Acer // 28. IX. 2016, 37°52’49.15’’N 14°1’5.72’’E, Baviera C. leg.’’(CBE, CBA). Types are four (all females).

Holotype. Female. Total length: 3.50 mm .. Slender body with elytra elongate-cylindrical. Dorsal vestiture with very imbricate, golden-brown scales with metallic sheen.

Rostrum covered by golden-brown scales, very transverse (length/width ratio 0.60), conical to the sides. Pterygia barely protruding from the rostrum. Epistome absent. Mesorostrum slightly concave, anteriorly with ten thin, short, curved, semi-erect setae. Wide and convex vertex, between eyes twice as wide as mesorostrum between antennae (ratio 2.00), with several, elongate, clavate, raised setae. Interocular space without visible fovea.

Lateral, large, slightly convex eyes protruding from outline of head. Antenna robust and short with recumbent, golden-silvery, widened setae. Antenna with ratio 0.67 (scape length: 0.70 mm, funicle length: 0.90 mm). Scape clubbed, short, slightly 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 5–7 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 transverse (length: 0.80 mm, width: 0.90 mm, ratio: 0.89), slightly sub-conical, slightly sinuate, with maximum width in the middle, less wide at base of its anterior margin, with short, widened-clavate, golden recumbent setae. Punctation usually covered by scales. Scutellum not visible.

Elytra (length: 2.30 mm, width: 1.35 mm, ratio: 1.70) vaulted dorsally, cylindrical, covered by golden-brown scales, with flat suture, wider at the middle. Elytral declivity with clavate raised setae (30°–45°). Punctation of striae, shallow, rather catenulate and impressed. Interstriae flat, with widened-clavate, quite elongate, golden, raised setae. Humeri short and rounded.

Legs quite short and robust clothed by golden-brown scales and rather short, widened golden setae. Femora little clubbed. Protibia with two acute spines on inner edge, with 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. 93 View FIGURES 60 – 98 ), sternite VIII ( Fig. 132 View FIGURES 99 – 137 ). Genitalia were examined in one specimens.

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

Distribution. See Fig. 141. Italian endemic. Known of Madonie Mountains (Pizzo Carbonara).

Etymology. Named from Latin word montivagus (feminine montivaga = wandering on the mountains).

Ecology and Phenology. Collected D. montivaga by Berlese and Winkler extractors from soil obtained sifting the leaf litter of Fagus sp. and Acer sp. on calcareous soil, in July and September, at elevations of 1750m.

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

Reproduction. Probably parthenogenetic. Species known from four females.
