A Baldorhynchus of medium size belonging to the blesioi group with elytra ogival or elongateoval. Within the species group, it is recognizeable by the elongate elytra (1.85–2.00 ratio) and the strongly short scape (0.75/0.80 ratio). The punctation of the pronotum is small, unordered, sparse and superficial. Punctation of elytra is small, slightly aligned, superficial and not isodiametric. Total length: 4.10–4.20 mm . Elytra with length/width ratio 1.85–2.00. Pronotum length 0.90 mm with length/ width ratio 1.10–1.20. Type series.

Bellò & Osella, 2015" [red, printed] (GOS). Paratype : “IT, Lombardia , BS, Monticelli Brusati , 627 Lo , 16 II 2013 , leg. Agosti , coll. Agosti ” ( MGR ). Types are one male and one female. All genitalia were estracted and examined. Holotype . Male. Total length: 4.10 mm . Rostrum elongate, about twice longer than head; dorsum convex; mesorostrum slightly gibbous, convex in the middle with a short keel; a dozen epistomal setae thin, curved, semierect. Antenna slender and elongate with long, semi-erect, thin setae; scape clavate and as robust as funicle. Scape length: 0.85 mm ; funicle length: 1.10 mm . Scape length/funicle length ratio: 0.77. Funicle with club ratios as follows: 12: 8: 5: 6: 4: 5: 4: 24 (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 with golden-yellowish pubescence. Vertex width / mesorostrum width: ratio 2.00. Vestigial eyes present, barely visible, partially covered by pubescence. Pronotum (length: 0.90 mm , width: 0.75 mm , ratio: 1.20) sub-cylindrical, sinuate at base, longer than wide, with maximum width in the middle; short golden erect seta inserted in center of hole; punctation superficial, small, sparse, isodiametric and of different widths, not uniformly arranged; large, smooth, shining central area on disc. Scutellum excavated, triangular. Elytra convex, elongate with high suture (length: 2.45 mm , width: 1.25 mm , ratio: 1.96, strongly rounded on sides, widest at basal third and strongly ogive-shaped on declivity. Punctation of striae small, superficial, not isodiametric, not same widths, little aligned, without setae; interspaces between strial punctation regular and less wide. Interstriae wider 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. 9f . Female. Similar to male only size slightly larger. Sternite VIII with sides sub-parallel of lamina and with apical margin fused. Spermatheca with cornu developed, ramus and nodulus almost inconspicuous ( Fig. 57 ). Ovipositor weakly sclerotized, gonocoxites tapered, with short styli and several more or less long setae. Distribution : See Fig. 129 . Italian endemic. Known only from “Monticelli Brusati” cave “1a Grotta di Gaina” at 410 meters of elevation: 45°38’47.10’’N 10°5’51.82’’E near Monticelli Brusati, Brescia. Etymology : Named for the collector of specimens, Mauro Agosti, agricultural entomologist and specialist on Carabidae . Ecology/Phenology. The cave opens at 400 meters of elevation in a fluvial-glacial deposit on maiolica and has a depth of + 2 with development of 15 meters. The paratype was collected in a pitfall trap filled with water. (Grottolo in litteris, 2015). Reproduction. Amphigonic.
