Stictoleptura dichroa, a North-East Asian taxon known from Russian Far East, China, Japan and Korea, has been described briefly from China (Sichuan) as Strangalia dichroa by Charles Émile Blanchard in 1871 [▿] and subsequently from North Japan as Leptura succedanea by George Lewis in 1879 [★]. For decades, the taxa dichroa and succedanea were considered to be independent species, but according to Mikhail Danilevsky it is one relatively variable species [☆] replacing the Euro-Asian taxon Stictoleptura (Aredolpona) rubra (Linnaeus, 1758) in its distribution area.

Body length:♂♂ 12 - 18 mm / ♀♀ 15 - 22 mm
Life cycle:2 years
Adults in:June - September
Host plant:larval development in dead wood of both coniferous and deciduous trees (Picea, Pinus, Abies, Larix, Populus)
Distribution:Russian Far East, China, Korea, Japan
