( Figures 33, 33a, 33b, 33c, 33d, 33e, 33f View FIGURES 33 – 33 , 63 View FIGURES 57 – 91 , 122 View FIGURES 92 – 126 )
Type locality. “Camorelli, 1210 m, Rogno, Bergamo” ( Fig. 138).
Diagnosis. A Baldorhynchus species of large size and oval shape belonging to the B. moczarskii group. Within the species group, it is distinguished by elytra sub-ovate, integument reddish-brown and disc of the pronotum plan and shiny. Punctation on the pronotum small, sparse and deep. Elytral punctution small, isodiametric, sparse, deep and perfectly aligned. Total length: 4.95–5.20 mm. Elytra with length/width ratio 1.93– 2.00. Pronotum length 1.00– 1.10 mm with length/width ratio 1.13–1.20.

Holotype. Female. Total length: 4.95 mm. Rostrum elongate and covered by dense golden-yellowish pubescence, about twice longer than the head; dorsum convex; mesorostrum rather gibbous; about ten epistomal setae thin, curved, semi-erect. Antenna elongate with long, semi-erect, thin setae; scape clavate and thin as funicle. Scape length: 1.00 mm; funicle length: 1.05 mm. Scape length/funicle length ratio: 0.95. Funicle with club ratios as follows: 13: 9: 6: 8: 5: 6: 5: 29 (club); fusiform club with first segment flat, shorter than last five funicle segments, at least twice wider than funicle. Head smooth on disc, short, conical. Supraorbital area partially covered by dense golden-yellowish pubescence. Vertex width / mesorostrum width: ratio 2.00. Vestigial eyes present, barely visible, covered by dense golden-yellowish pubescence. Pronotum (length: 1.00 mm, width: 0.88 mm, ratio: 1.13) subcylindrical, sinuate at the base, wider in the middle; short golden erect seta inserted in center of hole; deep punctation of different widths and uniformly arranged; smooth little central and longitudinal area on disc. Scutellum small, slightly excavated, triangular. Elytra convex, sub-oval with high suture (length: 2.90 mm, width: 1.50 mm, ratio: 1.93), strongly rounded on sides, widest on basal third and oval shaped on declivity.. Punctation of striae deep, isodiametric, only some with a minute and short seta; interspaces between strial punctation regular and wider than hole. Interstriae more or less as 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 toothlike tubercles on inner edge; protibia slightly curved in side view, metatibia and mesotibia straight.
Spiculum ventrale sub-parallel sides of lamina with apical margin fused. Spermatheca with cornu developed, ramus and nodulus inconspicuous ( Fig. 63 View FIGURES 57 – 91 ). Ovipositor weakly sclerotized, gonocoxites tapered, with short styli and several more or less long setae.
Male. Not known.
Distribution. See Fig. 132 View FIGURE 132 . Italian endemic. Known only from an old iron mine “Miniera sotto Camorelli” old mine at 1210 meters of elevation: 45°51’19.58’’N 10°6’6.34’’E in Camorelli near Rogno (Bergamo).
Etymology. Named after Giancarlo Branchi, passionate of minerals, as a gift for the valuable information about the location of several old mines.
Ecology/Phenology. The specimens were found in an old mine at 1210 meters of elevation. B. branchianus confirms a wider spread of the B. moczarskii- group even at higher elevations in the Orobian Pre-Alps, as observed for B. baldensis on Monte Baldo.
Reproduction. Parthenogenetic.
