Type locality. “Buso del Gato, loc. Loneri, Roverè, Verona”.

Diagnosis. A Baldorhynchus of medium size belonging to the B. baldensis group with elytra elongate-oval. Within the species group, it is recognisable by the short antennae and the gibbous pronotum (sub-hexagonal, curved sides). Punctation of pronotum is small or coarse, irregularly arranged, sparse and deep. Elytral punctation not small, aligned and very deep. Length 4.42–4.84 mm. Elytra with length/width ratio 1.85–1.90. Pronotum length 1.10–1.15 mm with length/width ratio 1.10–1.18.

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

Holotype. Female. Total length: 4.60 mm. Scape length: 0.95 mm; funicle length: 1.00 mm. Scape length/ funicle length ratio: 0.95. Funicle with club ratios: 11: 7: 4: 5: 4: 6: 5: 30 (club). Vestigial eyes present, barely visible. Vertex width/mesorostrum width: ratio 1.81. Pronotum ratio: 1.17 (length: 1.15 mm, width: 0.98 mm). Elytra ratio: 1.85 (length: 2.60 mm, width: 1.40 mm).

Distribution. See Fig.128. Italian endemic. Known only from “Grotta Buso del Gato” cave (1421 V /VR) at 676 meters of elevation: 45°35’29.40’’N 11°3’4.49’’E, Lessini Mountains.

Material. We examined both the material of Osella (1983) than Monguzzi (1999).

Other material. " Veneto, M. Lessini, (VR), Cerro Veronese, Gr. Buso del Gato , 3-V- [19’]91, leg. G. Trezzi " ( RMO): one female topotype; “ Veneto, Monti Lessini. Roverè Veronese (VR); Buso del Gatto (1421 V /VR), 685 m, 27.III.1986, E. Piva leg.” ( CBE): one male (remain). Genitalia of all specimens were examined.

Sexual dimorphism. In this species, the sexual dimorphism is strongly pronounced.

Ecology/Phenology. See Osella (1983) and Monguzzi (1999).

Reproduction. Amphigonic.

Systematic notes. Baldorhynchus lessinicus (Osella, 1983) nom. res. from Troglorhynchus amicalis ssp. lessinicus Osella (1983) = Otiorhynchus (Baldorhynchus) amicalis cenomanus ( Colonnelli & Magnano, 2003) . In addition, in this work, we elevate the taxon Otiorhynchus (Baldorhynchus) amicalis cenomanus (Osella, 1983) to species level as Baldorhynchus lessinicus (Osella, 1983) . The indicated collector (leg.) Mietto in the original description (Osella, 1983) is incorrect, Minetto is correct.
