Rhamnusium bicolor testaceipenne, a subspecies occurring from Ukraine through southern Russia to the Caucasus and Transcaucasia, has been described as from "Caucasus" as Rhamnusium testaceipenne by Maurice Pic in 1897 [✮]. The key difference of this subspecies from Rhamnusium bicolor bicolor (Schrank, 1781) is the same color pattern in males and in females - both always with red head, prothorax, elytra and legs; besides 5th antennal joint relatively wide; abdomen and femora bases partly darkened [❖][✳]. The biology of this subspecies is essentially identical to that of the nominotypical subspecies Rhamnusium bicolor bicolor.
Rhamnusium bicolor has been described from Vienna environs (Austria) by Franz von Paula Schrank in 1781 [▽].
