Type locality. “ Val Brembana, 1000 m, Oltre il Colle, Bergamo ”.

Diagnosis. A Baldorhynchus species oval shaped and of large size belonging to the B. moczarskii group. This species is recognisable by the elytra with eight/nine striae. The strongly sinuate pronotum and gibbose, carinate short rostrum. Punctation of the pronotum coarse, irregularly scattered, thick and deep. Elytral punctation small, thick, isodiametric, deep but not perfectly aligned. Total length: 4.90–5.00 mm. Elytra with length/width ratio 1.97–2.00. Pronotum length 1.00– 1.05 mm with length/width ratio 1.18–1.22.

Redescription. Considering that we have found the type, not seen by Osella (1968, 1983), we provide here its redescription.

Type with the following labels: [transparent label with genitalia] // ♀ [white, printed] // “Oltre il Colle, Alpen Bergam., 18 VII 13 ” [white, hand written] // “Typus” [red, printed] // “ex. Orig. Samlg. J. Breit Wien” [red, printed] // “ Troglorhynchus moczarskii Breit, Type!” [white, hand written] // Baldorhynchus moczarskii Breit, 1913, Holotype, det.

Holotype. Female. Total length: 4.90 mm. Rostrum elongate and covered by sparse golden-yellowish pubescence, about twice longer than the head; dorsum convex; mesorostrum gibbous; about eight epistomal setae thin, semi-erect. Antenna elongate with long, semi-erect, thin setae; scape clavate and as thin as funicle.

Scape length: 0.95 mm; funicle length: 1.05 mm. Scape length/funicle length ratio: 0.91. Funicle with club ratios as follows: 12: 8: 6: 7: 5: 6: 5: 28 (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 sparse golden-yellowish pubescence. Vertex width / mesorostrum width: ratio 1.85. Vestigial eyes present, barely visible, partially covered by yellowish pubescence. Pronotum (length: 1.05 mm, width: 0.86 mm, ratio: 1.22) sub-cylindrical, strongly sinuate at the base, wider in the anterior third; 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: 1.45 mm, ratio: 2.00), 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 six 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. 79). Ovipositor weakly sclerotized, gonocoxites tapered, with short styli and several more or less long setae.

Male. Not known.
