Baldorhynchus monguzzii Bellò & Osella sp. n.

( Figures 18, 18a, 18b, 18c, 18d, 18e, 18f , 80 , 109 )

Type locality. “ Buso della Torta , 875 m, Monte Grappa, Solagna, Vicenza”.

Diagnosis. A Baldorhynchus of large size belonging to the B. danzii group with elytra oval shaped. Within the species group, it is recognisable by the less shiny and less ovate elytra, scape robust and short. Punctation of the pronotum of different size, pocked, irregularly scattered, impressed and sparse. Elytral punctation grainy, slightly aligned, feebly impressed and isodiametric. Total length: 5.40 mm. Elytra with length/width ratio 1.875. Pronotum length mm 1.20 with length/width ratio 1.14.

Type series. Holotype, female: [transparent label with genitalia] // ♀ [white, printed] // " Veneto, M.[onte] Grappa, Grotta “ Busa de la Torta ”, (Solagna, VI), 8 IV 2000, L. Diotti ” [white, hand-written] // " Baldorhynchus monguzzii sp. n. , Holotype, det. Bellò & Osella, 2015" [red, printed] (RMO). Paratype: 1 ♀: Veneto, M.[onte] Grappa, Grotta “ Busa de la Torta ”, (Solagna, VI), 8 IV 2000, L. Diotti & R. Monguzzi legg. ( GOS): one female abdomen. Genitalia of one specimen was examined.

Holotype. Female. Total length: 5.40 mm. Rostrum elongate, about twice longer than the head; dorsum convex; mesorostrum rather gibbous, convex in the middle with a long keel; about 10 epistomal setae thin, curved, semi-erect. Antenna robust and short with long, semi-erect, thin setae; scape clavate and robust.

Scape length: 1.10 mm; funicle not present; club not present. Head smooth on disc, short, conical. Supraorbital area without golden-yellowish pubescence. Vertex width / mesorostrum width: ratio 2.00. Vestigial eyes not present, not covered by pubescence. Pronotum (length: 1.20 mm, width: 1.05 mm, ratio: 1.14) sub-cylindrical, sinuate at the base, longer than wide, with maximum width in the anterior third; short golden erect seta inserted in center of hole; punctation not deep, isodiametric and of different widths, not uniformly arranged; smooth central area on disc. Scutellum small, excavated, triangular. Elytra convex, elongate with high suture (length: 3.00 mm, width: 1.60 mm, ratio: 1.875), strongly rounded on sides, widest at middle and oval shaped. Punctation striae not deep, isodiametric and not same widths, without setae; interspaces between strial punctation smooth and regular, wider than hole. Interstriae less wide than striae, convex, smooth with sparse, long and erect setae. Legs robust and elongate, with rather long golden setae. Femora clubbed and edentate. Tibiae with seven tooth-like tubercles on inner edge. Protibia slightly curved in side view, metatibia straight and mesotibia curved inwards. Sternite VIII with sides curved of lamina and with apical margin fused. Spermatheca with cornu developed, ramus and nodulus inconspicuous ( Fig. 18f ).

Male. Not known.

Distribution. See Fig. 130. Italian endemic. Known only from “Monte Grappa” “Buso della Torta” Cave (N° 603 V VI) at 875 meters of elevation: 45°50’10.40’’N 11°43’28.58’’E in San Giorgio locality near Solagna (Vicenza). The cave opens at the base of the limestone cliff overlooking the Putifaia Valley in the South-West of the Monte Grappa massif, sloping down to the Valsugana Valley (Brenta River).

Etymology. Named for the eminent entomologist and passionate researcher of cave faunas Riccardo Monguzzi as a gift for his availability and valuable collaboration in this work.

Ecology/Phenology. It was collected from the water flow in pit-fall traps for endogean beetles.

Reproduction. Probably amphigonic like the other species of this group.
