( Figures. 6, 6a, 6b, 6c, 6d, 6e, 6f , 53 , 86 , 97 ) Type locality. “Malga Zovel, 1000 m , Monte Baldo, Verona” (Fig. 140). Diagnosis. A Baldorhynchus of medium size belonging to the B. baldensis group with elytra elongate-oval. Within the species group, it is recognizable for the short, robust legs and for the strongly gibbous pronotum (subesagonal, with sub-parallel lateral sides, at least in its basal part). Punctation of the pronotum small or coarse, irregularly scattered, sparse and strongly impressed. Punctation of the elytra small, irregularly aligned, slightly impressed. Total length: 4.50–4.90 mm . Elytra with length/width ratio 1.81–1.91 Pronotum length 1.20–1.30 mm with length/width ratio 1.22–1.25 Type series.

Rostrum elongate and partially covered by dense grey pubescence; less than twice longer than the head; dorsum convex; mesorostrum slightly gibbous and without keel; a dozen epistomal setae thin, curved, semi-erect. Antenna slender and elongate with long, semi-erect, thin setae; scape clavate and more robust than funicle. Scape length: 0.95 mm ; funicle length: 1.00 mm. Scape length/funicle length ratio: 0.95. Funicle segments ratios as follows: 11: 8: 5: 6: 5: 7: 5: 26 (club); fusiform club with first segment flat, shorter than five last funicle segments, at least twice wider than funicle. Head smooth on disc, short, conical. Supraorbital area covered by dense grey pubescence. Vertex width / mesorostrum width: ratio 1.67. Vestigial eyes present, barely visible, partially covered by grey pubescence. Pronotum (length: 1.30 mm , width: 1.04 mm , ratio: 1.25) sub-exagonal, strongly gibbous, sinuate at the base, wider in anterior third; short golden erect seta inserted in center of hole; punctation deep, isodiametric but of the different widths and not uniformly arranged; smooth little central area on disc. Scutellum small and inconspicuous. Elytra convex, elongate-oval with flat suture (length: 2.68 mm , width: 1.40 mm , ratio: 1.91), strongly rounded on sides, wider at basal third and ogive-shaped on declivity. Punctation of striae not deep, isodiametric but of different widths, only some with a minute and long seta; interspaces between strial punctation regular and less wide than hole. Interstriae as wide as striae, flat, smooth with sparse, long and erect setae. Legs robust and little elongate, with rather long golden setae. Femora clubbed and edentate. Tibiae with five tooth-like tubercles on inner edge; protibia slightly curved in side view, mesotibia and metatibia straight. Penis lengthened, sub-parallel seen from above and regularly and moderately curved in lateral view; tegmen sclerotized; small genital armature; penis apex as in Fig. 5f . Variation. Holotype has punctation of pronotum less deep than paratype . Female. Not known. Distribution. See Fig. 128. Italian endemic. Known only from the Western side of Mount Baldo from 1000 to 1200 meters above sea level. “Malga Zovel” cave is at 1000 meters of elevation: 45°42’23.96’’N 10°47’35.46’’E .

Etymology. Named by our friend and colleague Enrico Ruzzier who collected the holotype and actively participated in annual research on Mount Baldo. Ecology/Phenology. The holotype of B. ruzzieri was collected while sifting the litter of a Fagus forest below Malga Zovel. The paratype specimen was sifted from the litter at the foot of a Fagus tree in Trovaj valley. Reproduction . Amphigonic.
