7278DF3567AF55538F958E39FD369B8F.taxon	description	Description. Size: 3.3 – 4.2 mm (♂ 3.3 – 4.0 mm, ♀ 4.0 – 4.2 mm), Figs 1 – 4, 9, 11 – 15. Body colour: Black to dark brown, antennae and legs reddish brown. Head, rostrum and antennae: Head globose, irregularly punctate, raised broad dark brown scales on frons. Thinner, clubbed scales on epifrons up to antennal scrobes. Eyes weakly protruding, oval. Rostrum about twice as long as wide (L / B): 1.9 – 2.0; epifrons of rostrum shiny and irregularly striated-punctuated; rostral apex glossy and shiny, irregularly punctuated and with erect bowed setae; antennal scrobes visible from above, diverging towards eyes, in lateral view bowed downwards, limited by a horizontal ridge extending from lower end of eyes to lower limit of scrobes. Antennae strong, inserted on last third of rostrum; antennal scapes (L / B: 6.5) slender in its first third, then continuously broadened to three times as wide as width at base; dark brown, with clubbed scales from broad half of antennal scape; first segment of antennal funicles more than twice as long as wide, following segments as follows (L / B): 2 nd: 1.6, 3 rd to 7 th: 1.0; antennal clubs (L / B: 2.1) twice as wide as last antennal segment, consisting of three visible segments. Pronotum: Index (L / B): 1.12 – 1.14. Longer than wide, laterally weakly rounded, widest at middle, at fore and hind margins only weakly constricted; vestiture consisting of adherent and raised strong, clubbed mainly dark brown scales with several light brown scales intermixed, especially along middle. Elytra: Index (L / B): 1.53 – 1.71. Base slightly broader than prothorax, subelliptical, without humeral calli, oval, widest along middle; uneven intervals including suture weakly elevated, wider than deeply punctuated striae; elytral disc slightly flattened (lateral view); integument covered with two types of scales: semi-raised, short and rounded or oval scales, and raised clubbed scales, up to twice as long as wide. Scales mostly dark brown; several patchily arranged light brown scales intermixed. Legs: Strong and slender, with elongate, bowed, dark brown scales and thinner light brown scales; apex of tibiae with a pair of lobal formed spines, reminding of spurs, with their tips subparallel projecting ventrally (Figs 14, 15). Three visible tarsal segments, first and second of same length, third 1.5 × as long as wide and distally bilobed, fourth tiny, hardly visible, claw segment twice as long as third one, claws simple. Aedeagus: Base of penis evenly sclerotized; ostium of penis oval and discreet, twice as long as broad. Penis, towards distal tip, with basal half covered by a thin translucent sclerotized sheath; at anterior end of ostium, penis with long dagger-like apex (Figs 3, 4); internal sclerite with small central doublet and split inner arms with thick and bowed anterior arms surrounding central part. Encompassing sheath, valves forming a double lobed structure reminding of butterfly wings, as best seen in lateral view of single “ valve ”; sheath of internal sclerite evenly rounded, carrying lateral sclerites at middle of each of valves (Figs 11 – 13). Female genitalia: Sternite VIII (Fig. 18), spermatheca (Fig. 20) and gonocoxites (Fig. 22). Sexual dimorphism: Elytral shape of male laterally parallel (in females slightly convex), spurs of tibiae in males more pronounced than in females. Fifth sternite of males more broadly rounded apicad than in females, with a more pointed arch-like apical margin (Fig. 9). Derivation of the name: In deep gratitude and love the name of the new species was given by the first author to honor his wife Sonja, in compliance with provisions outlined by Lohse (1964).	en	Szallies, Alexander, Germann, Christoph (2025): A new Dichotrachelus Stierlin from Val Grande (Piemonte, Italy) (Coleoptera, Curculionidae) with comments on biogeography and evolution of high alpine species of the genus.
