E t y m o l o g y: The species name derives from the predominant findings at Monte Tremalzo in the border region between Trentino-South Tyrol and Lombardy. Additionally, the species has been documented at Cima Tombea in the same area. According to current knowledge, it is considered a local endemic of the "Massifs de Refuge" in the area west of Lake Garda.

Head shiny, unpunctuated, with weakly protruding eyes on the sides. Antennal segments: 1 short, 2 1.5 times longer than wide, 3-8 hardly longer than wide, different sizes among them, especially the spherical 8th smaller than 7th, its three-segmented club distinctly but not sharply demarcated. Pronotum slightly wider than long (1.2: 1), highly shiny with fine and weakly granular punctation, very sparse in the middle and denser towards the sides, widest just before the middle, evenly strongly rounded from there to the front, distinctly rounded converging narrowed towards the back, with very weakly bulging elevation in front of the base. Elytra narrower than long (1: 1.3), shiny and with significantly coarser granular punctation of varying density compared to the pronotum; widest just before the middle, sides evenly rounded. The basal grooves round, laterally weakly flattened extended, tomentum cushions at the inner front edge. In males, middle of foretibia distinctly thickened, with subsequent strong indentation towards its tip on the inner side ( Fig. 44 View Figs 41-45 ). Underside:♁ Metaventrite shiny, sparsely hairy, moderately indented in the middle.
