Dodomeira fossor Bellò & Baviera sp. n.

( Figures 30, 30a, 30b, 30c, 30d, 30e, 30f View FIGURES 30 – 30 , 43g View FIGURES 43 , 89 View FIGURES 60 – 98 , 128 View FIGURES 99 – 137 )

Type locality. Sardinia, Carbonia-Iglesias, Nebida ( Fig. 170 View FIGURE 170 ).

Diagnosis. A small-sized Dodomeira (3.40 mm) belonging to the pfisteri group with slender body (length/ width ratio: 1.69) and quite cylindrical elytra shape. Within the species group, it is recognisable by the small size, elytral declivity with recumbent (15°–30°) clavate-spatulate, short setae, rostrum with convergent sides towards the apex, protibia with only one acute spine on inner edge. Sizes: pronotum (length: 0.80 mm, width: 0.90 mm, ratio 0.89), elytra (length: 2.20 mm, width: 1.30 mm, ratio 1.69).

Type series. Holotype female with the following labels: [transparent label] genitalia in DHMF // [white, printed] ♀ // [white, printed]" I, Sardegna, CI, Nebida, 140m, vaglio macchia 28 I 2011 N 39°18.099' E 008°26.301' Bellò & Chemello legg. // [green, printed] “Collezione Cesare Bellò” // [red, printed] “ Dodomeira fossor sp. n., Holotype, det. Bellò 2016 ” ( CBE).

Holotype. Female. Slender body with elytra elongate-cylindrical. Total length: 3.40 mm. Dorsal vestiture with very imbricate and uniformely golden-brown scales with metallic sheen.

Rostrum covered by golden-brown scales, very transverse (length/width ratio 0.63) with convergent sides towards the apex. Pterygia barely protruding from the rostrum. Epistome absent. Mesorostrum slightly concave, anteriorly with eight-ten thin, curved, short and semi-erect setae. Vertex not wide (vertex width / mesorostrum width: ratio 1.70), quite convex and with several short clavate-spatulate semierect setae. Interocular space without fovea.

Lateral, large, convex eyes slightly protruding from outline of head. Antenna robust and short with recumbent, golden-silvery, widened setae. Antenna with ratio 0.76 (scape length: 0.65 mm, funicle length: 0.85 mm). Scape clubbed, slightly more robust than funicle, slightly curved at the basal third and progressively thickening towards apex. Funicle segments including club, relative lengths as follows: 10.5.3.3.3.3.3.15; all segments with widened setae silvery and segments 4–7 pearl-shaped. Club at least twice wider than funicle, short, fusiform with suture between first and second segment little visible.

Pronotum clothed with golden-brown scales, transverse (length: 0.80 mm, width: 0.90 mm, ratio: 0.89), subconical, sinuate, with maximum width in the middle, less wide at base of its anterior margin, with short, clavate, golden raised setae. Punctation usually covered by scales. Scutellum not visible.

Elytra (length: 2.20 mm, width: 1.30 mm, ratio: 1.69) vaulted dorsally, cylindrical, covered by golden-brown scales, with flat suture, wider at the middle. Elytral declivity with clavate-spatulate, short, recumbent (15°–30°). Punctation of striae, shallow, rather catenulate and impressed. Interstriae flat, with spatulate-clavate, short, golden, recumbent 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 one acute spine on inner edge, with mucro on inner apical angle. Protibia slightly 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. Claws very short and fused at base.

Female genitalia. See Figures: spermatheca ( Fig. 89 View FIGURES 60 – 98 ), sternite VIII ( Fig. 128 View FIGURES 99 – 137 ). Genitalia were examined in Holotype.

Distribution. See Fig. 141. Italian endemic. Known only from the type locality.

Etymology. Named from Latin word “ fossor ” (miner) because the type locality is in a mining area of Sardinia: the Iglesiente.

Ecology and Phenology. Collected by Berlese and Winkler extractors from soil obtained sifting the leaf litter of Mediterranean maquis in winter, at 100–200 meters. Numerous other investigations in the same area in winter and spring were negative.

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

Reproduction. Probably parthenogenetic. Species known from only one female.
