Type locality. “Serrada, Trentino”.

Diagnosis. A Baldorhynchus of medium size belonging to the B. ferrarii group. Within the group, it is recognisable by mesorostrum with one central keel and two lateral, the vertex width/mesorostrum width: ratio 1.85. Punctation of the pronotum coarse, irregularly scattered, dense and strongly impressed. Elytral punctation coarse, aligned, strongly impressed and isodiametric. Total length: 4.10 mm. Elytra with length/width ratio 1.77. Pronotum length 0.90 mm with length/width ratio 1.14.

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

Holotype. Male. Total length: 4.10 mm. Scape length: 0.88 mm. Funicle segments not present. Vestigial eyes present, barely visible, not covered by pubescence. Vertex width/mesorostrum width: ratio 1.85. Pronotum ratio: 1.14 (length: 0.90 mm, width: 0.79 mm). Elytra ratio: 1.77 (length: 2.30 mm, width: 1.30 mm).

Distribution. See Osella (1983) and Fig. 130.

Ecology/Phenology. There is no information.

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

Reproduction. Amphigonic.

Systematic notes. After the examination of the type of B. carinatus , we agree with Osella (1983) that the two species ( B. carinatus and B. ferrarii ) belong to the same species group and that B. carinatus is similar to B. ferrarii . Moreover, also the geographical distribution falls within the current distribution of the B. ferrarii group. Baldorhynchus carinatus (Osella, 1983) is nom. res. from synonymy of Troglorhynchus carinatus Osella (1983) with Otiorhynchus (Troglorhynchus) serradae Colonnelli & Magnano (2003) , replacement name based on homonymy with Otiorhynchus (Podoropelmus) carinatus (Paykull, 1792) .
