Type locality. “ Grotta L. Bertola, S. Anna di Alfaedo , 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 elongate antennae and the pronotum slightly gibbous (subhexagonal curved sides). The punctation of pronotum is small, irregularly arranged, quite sparse and deep. Punctation of the elytra slightly small, irregularly aligned and deep.

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

Holotype. Male. Total length: 4.80 mm. Scape length: 1.05 mm; funicle length: 1.10 mm. Scape length/funicle length ratio: 0.95. Antenna segments ratios: 12: 8: 7: 7: 5: 6: 5: 30 (club). Vestigial eyes present, barely visible. Vertex width/mesorostrum width: ratio 1.73. Pronotum ratio: 1.15 (length: 1.20 mm, width: 1.04 mm). Elytra ratio: 1.87 (length: 2.80 mm, width: 1.50 mm).

Distribution. See Fig 128. Italian endemic. Known only from “Grotta Lorenzo Bertola” (1120 V /VR) cave at 665 meters of elevation: 45°36’28.42’’N 10°57’56.98”E, Lessini Mountains.

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

Other material: “ Veneto, Monti Lessini. Sant’Anna d’Alfaedo (VR); Grotta Lorenzo Bertola (1120 V /VR), 600 m, 30.IV.2000, G. Peretto & E. Piva leg.” ( CBE): four males and six females (all remains). Genitalia of nine specimens (three males and six females) were examined.

Ecology/Phenology. See Osella (1983).

Reproduction. Amphigonic.

Systematic notes. In this work, we elevate the taxon Otiorhynchus (Baldorhynchus) amicalis caoduroi (Osella, 1983) to the species level as Baldorhynchus caoduroi (Osella, 1983) .
