Punctation of pronotum small, regularly arranged, isodiametric, not deep and not dense. Punctation of the elytra small, not isodiametric, not deep and regularly aligned. Total length: 4.20–4.60 mm. Elytra with length/width ratio 1.84–1.85. Pronotum length 1.00–1.00 mm with length/width ratio 1.18–1.18.

Holotype. Male. Total length: 4.20 mm. Rostrum elongate and covered by not dense white-grey pubescence; less twice longer than the head; dorsum convex; mesorostrum little gibbous. Antenna elongate with long, semierect, thin setae; scape clavate and more robust than funicle. Scape length: 0.95 mm; funicle length: 0.90 mm. Scape length/funicle length ratio: 1.05. Funicle with club ratios as follows: 11: 7: 5: 6: 5: 6: 6: 28 (club); fusiform club with first segment flat, long as the last five funicle segments, less twice wider than funicle. Head smooth on disc, short, conical. Supraorbital area partially covered by pubescence. Vertex width / mesorostrum width: ratio 1.58. Vestigial eyes present, visible, not covered by white-grey pubescence. Pronotum (length: 1.00 mm, width: 0.85 mm, ratio: 1.18) sub-cylindrical, sinuate at the base, wider in the anterior third; short erect seta inserted in center of hole; punctation small, not deep, not dense, isodiametric but of the different widths, uniformly arranged; little smooth central area on disc. Scutellum small, inconspicuous. Elytra convex, oval with strongly elevated suture (length: 2.35 mm, width: 1.28 mm, ratio: 1.84), strongly rounded on sides, widest at middle. Striae punctation is not deep, not isodiametric but regularly aligned, with a minute and long seta; interspaces between strial punctation regular and less wide hole. Interstriae as wide as striae, flat, smooth with sparse, long and erect setae. Legs thin and elongate, with rather long golden setae. Femora clubbed and edentate. Tibiae with seven little evident tooth-like tubercles on inner edge; protibia slightly curved in side view, metatibia and mesotibia straight. Penis lengthened, sub-parallel seen from above and regularly and moderately curved in lateral view; tegmen little sclerotized; penis apex as in Fig. 22f .

Distribution. See Fig. 130. Italian endemic. Known only from “Grotta of Convento a quota superiore” cave at 132 meters of elevation: 45°37’38.4’’N 11°26’30.9’’E at Isola Vicentina, in the eastern foothills of the Lessini Mountains.

Etymology. From Latin word, anachoreta (lonely man), for its isolated distribution.

Ecology/Phenology.
