Dodomeira bertoni Bellò View in CoL & Baviera sp. n.

( Figures 28, 28a, 28b, 28c, 28d, 28e, 28f View FIGURES 28 – 28 , 43e View FIGURES 43 , 87 View FIGURES 60 – 98 , 126 View FIGURES 99 – 137 )

Type locality. Sicily, Palermo, Monreale, Giacalone ( Fig. 168 View FIGURE 168 ).

Diagnosis. A small-sized Dodomeira (3.40–3.70 mm) belonging to the pfisteri group with slender body (length/width ratio: 1.70–1.71) and quite cylindrical elytra shape. Within the species group, it is recognisable by elytra elongate with spatulate flattened setae (00°–15°) and protibia with three acute spines on inner edge. Sizes: pronotum (length: 0.75–0.85 mm, width: 0.80–0.90 mm, ratio 0.94), elytra (length: 2.1 7– 2.35 mm, width: 1.27– 1.38 mm, ratio 1.70–1.71).

Type series. Holotype female with the following labels: [transparent label] genitalia in DHMF // [white, printed] ♀ // [white, handwritten]"Giacalone, PA [Palermo], 18.XI. [19]’90, leg. Bellò” // [white, printed]”Sotto pietra” // [green, printed] “Collezione Cesare Bellò” // [red, printed] “ Dodomeira bertoni sp. n., Holotype, det. Bellò 2016 ” ( CBE).

Paratypes. 1 female: "Giacalone, PA [Palermo], sotto pietra, 18.XI. [19] ’90, leg. Bellò” (CBA);

1 female:"Monreale, PA [Palermo], Giacalone, sotto pietra, 18.XI. [19] ’90, leg. Pierotti” (HPI).

Types are three (all females).

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

Rostrum covered by golden-brown scales, quite sub-square (length/width ratio 0.85), sub-parallel to the sides. Pterygia barely protruding from the rostrum. Epistome absent. Mesorostrum slightly concave, anteriorly with twelve thin, curved, short and semi-erect setae. Vertex quite wide and convex (vertex width / mesorostrum width: ratio 1.84) with several, elongate, clavate-spatulate, raised setae. Interocular space with visible fovea.

Lateral, quite small, convex eyes barely protruding from outline of head. Antenna quite 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, curved at the basal third and progressively thickening towards apex. Funicle segments including club, relative lengths as follows:; all segments with widened setae silvery; and segments 5–7 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, quite sub-square (length: 0.75 mm, width: 0.80 mm, ratio: 0.94), sub-conical, with maximum width in the middle, less wide at base of its anterior margin, with short, clavatespatulate, golden flattened setae. Punctation usually covered by scales. Scutellum not visible.

Elytra (length: 2.17 mm, width: 1.27 mm, ratio: 1.71) quite vaulted dorsally, cylindrical, covered by goldenbrown scales, with flat suture, wider at the middle. Elytral declivity with quite spatulate and flattened setae (00°– 15°). Punctation of striae, shallow, rather catenulate and impressed. Interstriae flat, with spatulate-clavate, short, golden, flattened 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 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 very short and transverse; segment 3 shallowly bilobed; all segments with thin golden setae. Onychium curved, robust and very short. Claws very short and fused at base.

Female genitalia. See Figures: spermatheca ( Fig. 87 View FIGURES 60 – 98 ), sternite VIII ( Fig. 126 View FIGURES 99 – 137 ). Genitalia were examined in two specimens.

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

Distribution. See Fig. 141. Italian endemic. Known only from the type locality, Giacalone at 700–800 meters a.s.l..

Etymology. This species named after Berton (Rita & Piero), friends of the first author, in appreciation of their important graphic contribution in this and other works.

Ecology and Phenology. Collected during a rainy month of November on a slope calcareous looking at the edges or under small stones. Repeated investigations in the spring and summer gave negative results suggesting that D. bertoni are absent during this time.

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

Reproduction. Probably parthenogenetic. Species known from three females.

Chorological relationships. Sympatric with Dolichomeira dubia Pierotti & Bellò, 1994 .
