( Figures 23, 23a, 23b, 23c, 23d, 23e, 23f , 50 , 76 , 112 )

Type locality. “Prefond del Gas, 264 Lo, 1140 m, Magasa, Brescia”.

Diagnosis. A Baldorhynchus of medium size belonging to the B. ferrarii group. Within the species group it is recognisable by the reddish oval elytra (brown in the other species), the elongate rostrum with dense goldenyellowish pubescence covering the same. Punctation of the pronotum rather small, dense, and deep, regularly scattered. Elytral punctation slightly coarse, regularly aligned, strongly impressed and isodiametric.Total length: 4.20–4.35 mm. Elytra with length/width ratio 1.78–1.81. Pronotum length 0.90–0.95 mm with length/width ratio 1.12–1.15.

Type series. Holotype male: [transparent label with genitalia] // ♂ [white, printed] // " Lombardia (BS), Prefond del Gas, Magasa , 12. VII. [20]03, Leg. Grottolo” [white, printed] // " Baldorhynchus magasaensis sp. n. , Holotype, det. Bellò & Osella, 2015" [red, printed] (GOS). Types are only male holotype and genitalia were examined.

Other material. "Valvestino (BS), Magasa, 1000 m, 29.VI.1979, leg. Monguzzi" ( RMO): one female determined cf. Baldorhynchus magasaensis ; “Judicarien, Süd-Tirol, Cima Tombea // Sammlung Stöcklein” [white, printed and hand-written] ( NHMB): one female with very evident eyes determined cf. Baldorhynchus magasaensis .

Holotype. Male. Total length: 4.35 mm. Rostrum elongate and covered by by dense golden-yellowish 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: 1.00 mm; funicle length: 0.90 mm. Scape length/funicle length ratio: 1.11. Funicle with club ratios as follows: 11: 7: 5: 6: 5: 6: 6: 27 (club); fusiform club with first segment strongly flat, longest of last five funicle segments, less twice wider than funicle.

Head smooth on disc, short, conical. Supraorbital area covered by pubescence. Vertex width / mesorostrum width: ratio 1.66. Vestigial eyes present, barely visible, partially covered by golden-yellowish pubescence. Pronotum (length: 0.95 mm, width: 0.85 mm, ratio: 1.12) sub-cylindrical, sinuate at the base, almost as wide as long, wider in the anterior quarter; long erect seta inserted in center of hole; punctation deep, isodiametric but of the different widths, almost uniformly arranged; little smooth central area on disc. Scutellum small, excavated, triangular. Elytra convex, oval with elevated suture (length: 2.40 mm, width: 1.33 mm, ratio: 1.81), strongly rounded on sides, widest at middle. Striae punctation is deep, isodiametric and same widths on elitral disc, 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 five/six 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; small genital armature; penis apex as in Fig. 23f .

Distribution. See Fig. 130. Italian endemic. Known only from “Prefond del Gas” cave at 1140 meters of elevation in Valvestino Valley locality near Magasa (Brescia).

Etymology. Named after Magasa, the type locality.
