Baldorhynchus settei Bellò & Osella sp. n.

( Figures 25, 25a, 25b, 25c, 25d, 25e, 25f , 88 , 114 )

Type locality. “ Val Revolto , 900 m, Lessinia, Verona”.

Diagnosis. A Baldorhynchus of medium size belonging to the B. ferrarii group. Within the species group, it is recognisable by the not elongate rostrum, pronotum with the maximum width in the forequarter (in the middle for the other species) and tibiae without tooth-like tubercles on inner edge. Punctation of the pronotum coarse / pocked, irregularly scattered, dense and deep. Elytral punctation slightly coarse, regularly aligned, feebly impressed and not isodiametric. Total length: 4.20 mm. Elytra with length/width ratio 1.84. Pronotum length 0.88 mm with length/width ratio 1.13.

Type series. Holotype female: [transparent label with genitalia] // ♀ [white, printed] // " Parco Lessinia (VR) Val Revolto, mt. 900, Trappole, m.s.s., dal 27 IV al 23 VII 2012, Leg.

Types are only female holotype and genitalia were examined.

Holotype. Female. Total length: 4.20 mm. Rostrum not elongate and not covered by pubescence; less twice longer than the head; dorsum convex; mesorostrum gibbous with plate-shaped sub-rhomboid and flanged. Antenna elongate with long, semi-erect, thin setae; scape clavate and as robust as funicle. Scape length: 0.85 mm; funicle length: 0.80 mm. Scape length/funicle length ratio: 1.06. Antenna segments ratios as follows: 11: 7: 4: 4: 4: 5: 4: 28 (club); fusiform club with first segment much flat, longest of last five funicle segments, less twice wider than funicle. Head smooth on disc, short, conical. Supraorbital area not covered by pubescence. Vertex width / mesorostrum width: ratio 1.30. Vestigial eyes not present and area not covered by pubescence. Pronotum (length: 0.88 mm, width: 0.78 mm, ratio: 1.13) sub-cylindrical, sinuate at the base, almost as wide as long, wider in the anterior quarter; long erect seta inserted in center of hole; punctation deep, not isodiametric and of the different widths, not uniformly arranged; little smooth central area on disc. Scutellum small, excavated, triangular. Elytra convex, briefly elongate-oval with elevated suture (length: 2.40 mm, width: 1.30 mm, ratio: 1.84), strongly rounded on sides, widest at middle and ogive-shaped on declivity. Punctation of striae deep, isodiametric and of the different widths with a minute and long seta; interspaces between strial punctation regular and less wide hole. Interstriae as wide as striae, flat, smooth with sparse, long and erect setae. Legs thin and elongate, with rather long golden setae. Femora clubbed and edentate. Tibiae without tooth-like tubercles on inner edge; protibia slightly curved in side view, metatibia and mesotibia straight. Sternite VIII with sides sub-parallel of lamina and with apical margin fused. Spermatheca with cornu, ramus and nodulus developed ( Fig. 25f ).

Male. Not known.

Distribution. See Fig. 130. Italian endemic. Known only from Revolto Valley “Val Revolto” at 900 meters of elevation: 45°40’22.79’’N, 11°07’02.16’’E in Lessinia (Verona).

Etymology. Named after our friend and colleague Alberto Sette who collected the specimen and whose researches are of fundamental importance for the knowledge of the biodiversity of the Verona province. Ecology/Phenology. The holotype was collected with pitfall traps located in the Superficial Subterranean Habitat (see Giachino & Vailati, 2010) of the Revolto Valley in a Fagus and Corylus forest (Sette in litteris, 2015). Reproduction. Probably amphigonic like the other species of this group.
