( Figures 36, 36a, 36b, 36c, 36d, 36e, 36f , 83 , 125 ) Type locality. “Monte Vaccareggio Ovest, 1250 m , Dossena, Bergamo” (Fig. 144). Diagnosis. A Baldorhynchus species of oval shape and large size species belonging to the B. moczarskii group. Within the species group, it is distinguished for an intermediate body size, the elytra with ten striae, the second funicle segment strongly stretched (almost twice longer than seventh) and the antennal club short. Punctation on the pronotum dense, dull, wrinkled, and quite regularly arranged. Elytral punctation coarse, isodiametric, not dense, deep and regularly aligned. Total length: 5.00– 5.30 mm . Elytra with length/width ratio 1.95–2.00. Pronotum length 1.00– 1.05 mm with length/width ratio 1.11–1.17. Type series.

Pedersoli D."( CBE , MGR ): two females. Types are ten females. Genitalia of three were examined. Holotype . Female. Total length: 5.30 mm . Rostrum elongate and covered by brown-yellowish pubescence; about twice longer than the head; dorsum convex; mesorostrum rather gibbous; a dozen epistomal setae thin, curved, semi-erect. Antenna strongly slender and elongate with long, semi-erect, thin setae; scape clavate and thin as funicle. Scape length: 1.10 mm ; funicle length: 1.15 mm . Scape length/funicle length ratio: 0.96. Funicle with club ratios as follows: 13:9:7:8:5:6:5: 26 (club); fusiform club with first segment flat, longest of last four funicle segments, at least twice wider than funicle. Head smooth on disc, short, conical. Supraorbital area partially covered by brown-yellowish pubescence. Vertex width / mesorostrum width: ratio 2.00. Vestigial eyes present, barely visible, partially covered by brown-yellowish pubescence. Pronotum (length: 1.05 mm , width: 0.95 mm , ratio: 1.11) sub-square, sinuate at the base, wider in the middle; short golden erect seta inserted in center of hole; punctation strongly deep, isodiametric but of different widths and not uniformly arranged; smooth little central area on disc. Scutellum small, slightly excavated, triangular. Elytra convex, elongate-oval with high suture (length: 3.20 mm , width: 1.60 mm , ratio: 2.00), strongly rounded on sides, widest at basal third and ogive-shaped on declivity. Punctation of striae deep, isodiametric but of different widths, only some with a minute and short seta; interspaces between strial punctation regular and less wide than hole. Interstriae less wide than striae, flat, smooth with sparse, short and erect setae. Legs thin and elongate, with rather long golden setae. Femora clubbed and edentate. Tibiae with seven/eight 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 developed, ramus and nodulus inconspicuous ( Fig. 83 ). Ovipositor weakly sclerotized, gonocoxites tapered, with short styli and several more or less long setae. Male. Not known.

Distribution. See Fig. 132 . Italian endemic. Known only from an old mine on “Monte Vaccareggio” at 1250 m near Dossena, Bergamo. Etymology. Named after our young colleague Davide Pedersoli as a gift for his ability to discover this interesting new species and for his valuable collaboration on researches in the caves. Ecology/Phenology. Specimens were collected in an iron mine. B. pedersolii confirms a wider spread of the moczarskii- group even at higher elevations in the Orobie Pre- Alps, as observed for B. baldensis on Monte Baldo. Reproduction. Probably parthenogenetic. Species known only from ten females.
