This one is quite amazing, it features some differences with the standard shaping of A. sinicum (pronotal protrusion, lack of apical spines on elytra..).
I would like to have the opinion of Alain on this variation...

Je reviens sur ce post car finalement je pense peut-être à un cas de specimen tératogénique de sinicum.
Déformation du pronotum dans la zone basale.
Ces malformations peuvent être d'origine génétique ou le résultat de conditions particulières au stade pré-imaginal.
Je présente également ci-dessous un cas similaire sur un dorysthenes granulosus (insectes normaux à gauche).
