Baldorhynchus bodeianus Bellò & Osella sp. n.

( Figures 10, 10a, 10b, 10c, 10d, 10f , 41 , 62 , 101 )

Type locality. “Bus de la Vecia, N° 193 Lo, Monte Covolo, 265 m, Gavardo, Brescia” ( Fig. 134 ).

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 general small size and for the first funicle segment twice longer than the second. Punctation of pronotum large, irregularly arranged, deep and dense. Punctation of the elytra as the pronotum, almost regularly aligned. Total length 3.90–4.50 mm. Elytra with length/width ratio 1.90–2.03. Pronotum length 0.90–1.00 mm with length/width ratio 1.20–1.25.

Holotype. Male. Total length: 4.09 mm. Rostrum elongate and covered by dense golden-yellowish pubescence; about twice longer than the head; dorsum convex; mesorostrum rather 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: 0.80 mm; funicle length: 0.80 mm. Scape length/funicle length ratio: 1.00. Funicle with club ratios as follows: 12: 6: 4: 5: 4: 4: 5: 25 (club), fusiform club with first segment flat, longest of five last funicle segments, at least twice wider than funicle. Head smooth on disc, short, conical. Supraorbital area covered by dense golden-yellowish pubescence. Vertex width / mesorostrum width: ratio 1.80. Vestigial eyes present, almost covered by dense golden-yellowish pubescence. Pronotum (length: 0.96 mm, width: 0.81 mm, ratio: 1.19) sub-cylindrical, sinuate at the base, clearly longer than wide, wider in the middle; short golden erect seta inserted in center of hole; punctation deep, isodiametric but of different widths and not uniformly arranged; smooth central area on disc. Scutellum small, excavated, triangular. Elytra convex, elongate-oval with flat suture (length: 2.25 mm, width: 1.18 mm, ratio: 1.90), strongly rounded on sides, widest at basal third and ogive-shaped on declivity. Punctation of striae deep, isodiametric but of different widths; only some with a minute and long 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 sclerotized; small genital armature; penis apex as in Fig. 10f .

Variation. The holotype has punctation of pronotum less deep than paratypes and rather sparse.

Female. Similar to males only size slightly larger, elytral length 2.60 mm and width 1.30 mm with ratio 2– 2.03. Sternite VIII with sides sub-parallel of lamina and with apical margin fused. Spermatheca with cornu, ramus and nodulus developed ( Fig. 62 ). 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 de la Vecia” cave at 265 meters of elevation: 45°35’48.41’’N 10°27’40.00’’E in Covolo Mount locality near Gavardo (Brescia).

Etymology. Named for the collector of specimens Luca Bodei who discovered this species.

Ecology/Phenology. All the specimens were found in one cave. The cave opens in the Lias limestone formation (Jurassic). The cave fauna is quite rich and includes, after B. bodeianus sp. n., the following species: Androniscus dentiger calcivagus Verhoeff (Isopoda) , Armadillidium (Marginiferum) marmorivagum Verhoeff (Isopoda) , Trogloiulus boldorii Manfredi (Julida) , Japyx sinuosus Tuxen (Diplura) , Antisphodrus monguzzii Casale (Coleoptera) , Boldoria vestae meridionalis Vailati (Coleoptera) ( Boldori, 1969; Grottolo & Martinelli, 1990; Vailati, 1988; Grottolo in litteris, 2015).

Reproduction. Amphigonic.
