Type locality. “Cima Avez, 1840 m, Tremalzo, Trentino”.

Diagnosis. A Baldorhynchus of small size belonging to the B. kahleni group. This species is recognisable by the sub-oval elytra (sub-elongate in the other species) and more elongate antennae. Punctation of the pronotum coarse / pocked, irregularly scattered, dense and deep. Elytral punctation small, regularly arranged, feebly impressed and isodiametric. Total length: 3.95 mm. Elytra with length/width ratio 1.91. Pronotum length 0.80 with length/width ratio 1.10.

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

Holotype. Female. Total length: 3.95 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:.3: 4: 5: 4: 26 (club). Vestigial eyes not present, barely visible, partially covered by golden-yellowish pubescence. Vertex width/mesorostrum width: ratio 2.00. Pronotum ratio: 1.10 (length: 0.80 mm, width: 0.73 mm). Elytra ratio: 1.91 (length: 2.20 mm, width: 1.15 mm).

Distribution. See Osella (1983) and Fig. 131.

Material. We examined the material studied by Osella (1983).

Ecology/Phenology. See Osella (1983).

Reproduction. Probably amphigonic like the other species of this group.
