Type locality. “Toscolano, 600 m, Val di Campiglio , Brescia ”.

Diagnosis. A Baldorhynchus of small size belonging to the B. kahleni group. Within the species group, it is recognisable by the strongly carinate rostrum and the vertex width/mesorostrum width ratio: 1.6 (2.0 in the other species). Punctation of the pronotum small, irregularly scattered, slightly dense and deep. Elytral punctution small, regularly arranged, deep and isodiametric. Total length: 3.85 mm. Elytra with length/width ratio 1.96. Pronotum length 0.75 with length/width ratio 1.04.

Description. See Osella (1983) and figures hoc opus.

Holotype. Male. Total length: 3.85 mm. Scape length: 0.80 mm; funicle length: 0.80 mm. Scape length/funicle length ratio: 1.00. Funicle with club ratios: 9: 6: 4:.4: 4: 5: 4: 26 (club). Vestigial eyes present, visible, not covered by pubescence. Vertex width/mesorostrum width: ratio 1.60. Pronotum ratio: 1.04 (length: 0.75 mm, width: 0.72 mm). Elytra ratio: 1.96 (length: 2.20 mm, width: 1.12 mm).
