( Figures 24, 24a, 24b, 24c, 24d, 24e, 24f View FIGURES 24 – 24 , 52 View FIGURES 38 – 56 , 84 View FIGURES 57 – 91 , 113 View FIGURES 92 – 126 )
Type locality: “Grotta del Covoletto (39 V /VI), 316 m, Monti Lessini, Cornedo, Vicenza”.
Diagnosis. A Baldorhynchus of medium size belonging to the B. ferrarii group. Within the species group, it is easily recognisable to be the largest species with robust legs and strongly clubbed femora. Punctation of pronotum small, irregularly arranged, isodiametric, not deep but dense. Punctation of the elytra small, isodiametric, not deep and regularly aligned. Total length: 4.40–4.90 mm. Elytra with length/width ratio 1.80–1.80. Pronotum length 1.00– 1.15 mm with length/width ratio 1.14–1.15.
Type series. Holotype male: [transparent label with genitalia] // ♂ [white, printed] // “468, Veneto, Monti Lessini, Cornedo (VI)” [white, hand-written] // “468, Grotta del Covoletto (39 V /VI), 330 m ” [white, hand-written] // “ 23.X.1984, E. Piva leg.” [white, hand-written] // “ Otiorhynchus (Baldorhynchus) adrianoi —E. Colonnelli det. 2010” [white, hand-written and printed] // " Baldorhynchus pivai sp. n., Holotype, det. Bellò & Osella, 2015" [red, printed] (GOS). Paratypes: “Veneto, Monti Lessini, Cornedo (VI), Grotta del Covoletto (39 V /VI) 330 m, 23.X.1984, E. Piva leg.” (CBE): one male and two females; “Veneto, Monti Lessini, Cornedo (VI), Grotta del Covoletto (39 V /VI) 330 m, 23.X.1984, E. Piva leg.” (CBE): two females (abdomen + abdomen with pronotum); “Veneto, Monti Lessini, Cornedo (VI), Grotta del Covoletto (39 V /VI) 330 m, 23.X.1984, I. Ferrari leg.” (CBE): one male (abdomen). Types are seven specimens (three males and four females). Genitalia of five (two males and two females) were examined.
Holotype. Male. Total length: 4.90 mm. Rostrum elongate and covered by not dense grey pubescence; less twice longer than the head; dorsum convex; mesorostrum little gibbous. Antenna elongate with long, semi-erect, thin setae; scape clavate and more robust than funicle. Scape length: 1.10 mm; funicle length: 1.00 mm. Scape length/funicle length ratio: 1.10. Funicle with club ratios as follows: 12: 8: 5: 6: 5: 7: 6: 30 (club); fusiform club with first segment flat, less long than 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 1.66. Vestigial eyes present, visible, not covered by pubescence. Pronotum (length: 1.15 mm, width: 1.00 mm, ratio: 1.15) sub-cylindrical, sinuate at the base, wider in the anterior third; short erect seta inserted in center of hole; punctation small, irregularly arranged, isodiametric but of the different widths, not deep but dense; little smooth central area on disc. Scutellum small, visible. Elytra convex, oval with little elevated suture (length: 2.70 mm, width: 1.50 mm, ratio: 1.80), strongly rounded on sides, widest at middle. Striae punctation is not small, not deep, 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 robust and not elongate, with rather long golden setae. Femora strongly clubbed and edentate. Tibiae with six/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. 24f View FIGURES 24 – 24 .
Distribution. See Fig. 130. Italian endemic. Known from “Grotta of Covoletto” cave at 316 meters of elevation: 45°37’0.5’’N 11°22’21.7’’E at Cornedo Vicentino, in the eastern foothills of the Lessini Mountains.
Etymology. Named after our collegue Erminio Piva, eminent Carabidae specialist, whose research on the endogean fauna of the Lessini Mountains made the discovery of this and other, interesting species possible.
Ecology/Phenology. One specimen bears on a transparent label a parasitic mite. Piva (in litteris, 2015) reports in the cave "Grotta of Covoletto" the presence, toghether with B. anachoreta sp. n., of the following species of Coleoptera : Carabidae Sphodrinae , Laemostenus (Antisphodrus) schreibersi (Küster, 1846) ; Carabidae Trechinae , Orotrechus vicentinus vicentinus (Gestro, 1907) and Orotrechus pominii Tamanini, 1953 ; Cholevidae Leptodirinae , Neobathyscia fabianii (Dodero, 1904) and Lessiniella trevisioli Pavan, 1941 .
Reproduction. Amphigonic.
