( Figures 11, 11a, 11b, 11c, 11d, 11e, 11f , 45 , 70 , 102 )

Type locality. “Bus del Fich, N° 78 Lo, 260 m, Santuario, Paitone, Brescia” ( Fig. 135).

Diagnosis. A Baldorhynchus of medium size belonging to the B. blesioi group with elytra ogival or elongateoval. Within the species group, it is recognizeable for the normal size, no smooth areas on the disc of the pronotum and elongate antennal club. Punctation of pronotum large, irregularly arranged, deep and dense. Punctation of the elytra coarse, thick, deep, isodiametric but not regularly aligned. Total length: 4.25–4.90 mm. Elytra with length/ width ratio 2.00–2.07. Pronotum length 0.95–1.10 mm with length/width ratio 1.10–1.20.

( DVA), two abdomens.

Holotype. Male. Total length: 4.25 mm. Rostrum elongate and covered by dense golden-yellowish pubescence, more than twice as long as the head; dorsum convex; mesorostrum gibbous; a dozen epistomal setae thin, curved, semi-erect. Antenna slender and elongate with long, semi-erect, thin setae; scape clavate and as robust as funicle. Scape length: 0.90 mm; funicle length: 0.90 mm. Scape length/funicle length ratio: 1.00. Funicle with club ratios as follows: 11: 8: 4: 5: 4: 5: 5: 29 (club); fusiform club with first segment flat, longest of last five funicle segments, at least twice wider than funicle. Head smooth on disc, short, conical. Supraorbital area partially covered by dense golden-yellowish pubescence. Vertex width / mesorostrum width: ratio 1.71. Vestigial eyes present, partially covered by dense golden-yellowish pubescence. Pronotum (length: 0.99 mm, width: 0.86 mm, ratio: 1.15) sub-cylindrical, sinuate at the base, wider in the middle; short golden erect seta inserted in center of hole; punctation rather deep, isodiametric but of different widths and not uniformly arranged. Scutellum small, excavated, triangular. Elytra convex, elongate-oval with elevated suture (length: 2.46 mm, width: 1.23 mm, ratio: 2.00), strongly rounded on sides, widest at middle and ogive-shaped on declivity. Punctation of striae deep, not isodiametric but of different widths, only some with a minute and short seta; interspaces between strial punctation regular and less wide than hole. Interstriae less wide than 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 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 sclerotize; small genital armature; penis apex as in Fig. 11f .

Female. Similar to males only size slightly larger, elytral length 2.85 mm and width 1.40 mm with ratio 2.04. Sternite VIII with sides sub-parallel of lamina and with apical margin fused. Spermatheca with cornu, ramus and nodulus developed ( Fig. 70 ). Ovipositor weakly sclerotized, gonocoxites tapered, with short styli and several more or less long setae.

Distribution. See Fig. 129 . Italian endemic. Known only from “Bus del Fich” cave at 260 meters of elevation: 45°33’29.40’’N 10°23’28.47’’E in Santuario near Paitone (Brescia).

Etymology. For the Latin, word “ deceptor ” (deceptive) since his species was not originally recognized because of its similarity to B. bodeianus sp. n. and B. grottoloi sp.n.

Ecology/Phenology. All the specimens were been found in one cave. The cave opens in limestones of the lower Lias (Sinemurian—Hettangiano) (Grottolo in litteris, 2015). Inside it has been reported ( Boldori, 1969; Grottolo & Martinelli, 1990; Vailati, 1988) the presence, even in sintopy with B. deceptor sp. n., of the following species: Euscorpius italicus Herbst (Scorpiones) , Androniscus subterraneus boldorii Strouhal (Isopoda) , Trichoniscus mancinii Brian (Isopoda) , Allegrettia boldorii Jeannel (Coleoptera) , Antisphodrus reissi boldorii Dodero (Coleoptera) , Boldoriella humeralis Dodero (Coleoptera) .

Reproduction. Amphigonic.
