Holotype. Female. Total length: 4.40 mm. Rostrum short and partially covered by dense yellowish pubescence; twice as long as the head; dorsum convex; mesorostrum slightly gibbous with short keel; a dozen epistomal setae thin, curved, semi-erect. Antenna slender and little elongate with long, semi-erect, thin setae, scape little clavate and as robust as funicle. Scape length: 0.90 mm; funicle length: 0.85 mm. Scape length/funicle length ratio: 1.05. Antenna segments ratios as follows: 10: 7: 5: 6: 5: 5: 4: 28 (club); fusiform club with first segment flat, more long than five last funicle segments, at least twice wider than funicle. Head smooth on disc, short, conical. Supraorbital area covered by dense yellowish pubescence. Vertex width / mesorostrum width: ratio 1.72. Vestigial eyes visible, partially covered by yellowish pubescence. Pronotum (length: 1.05 mm, width: 0.90 mm, ratio: 1.17) little sub-exagonal, not gibbous, little sinuate at the base, wider in the middle; short golden erect seta inserted in center of hole; punctation large, dense, isodiametric, regularly arranged and strongly impressed; smooth little central area on disc. Scutellum small and inconspicuous. Elytra convex, elongate-oval with flat suture (length: 2.45 mm, width: 1.25 mm, ratio: 1.96), strongly rounded on sides, wider at the middle and ogive-shaped on declivity. Punctation of striae large, regularly aligned, isodiametric and slightly impressed; interspaces between strial punctation regular and less wide than hole. Interstriae as wide as striae, flat, smooth with sparse, long and erect setae. Legs robust and elongate, with rather long golden setae. Femora clubbed and edentate. Tibiae with seven/ eight tooth-like tubercles on inner edge; protibia slightly curved in side view, mesotibia and metatibia straight.

Sternite VIII with sides sub-parallel of lamina and with apical margin fused. Spermatheca with cornu developed, ramus and nodulus almost inconspicuous.

Male. Penis lengthened, sub-parallel seen from above and regularly and moderately curved in lateral view; tegmen sclerotized; small genital armature; penis apex as in Fig. 5f .

Distribution. See Fig. 128. Italian endemic. Known only from the Lessini Mountains, Fumane valley. “Grotta Vaio Pangoni” cave is at 592 meters of elevation: 45°34’29.6’’N 10°52’40.2’’E.

Etymology. Named after our friend and colleague Alessandro Paladini for his uncommon ability in research of endogean Curculionidae .

Ecology/Phenology. The cave fauna is not rich and includes, after B. paladinii sp. n., only the Carabidae Trechinae Orotrechus vicentinus juccii Pomini, 1940 (Piva in litteris, 2015).

Reproduction. Amphigonic.
