Note.

According to Nikitsky (2007), this genus comprises 19 world species, distributed in the Russian Far East, Korea, China, Japan, Oriental region, and in the Nearctic region. In North America, there is a single species: Holostrophus bifasciatus (Say). In further justifying his separation of the genera Pseudoholostrophus and Holostrophus , Nikitsky (1998: 40) stated that "it seems noteworthy that species of Pseudoholostrophus display the elytra either one-color but not black or with a light humeral spot only, or with a clarified diffused transverse fascia in basal part. A more clearly evident reddish-yellow or red spotty pattern of the elytra is characteristic of Holostrophus , not Pseudoholostrophus ". Nikitsky (2007) added a new subgenus ( Paraholostrophus ), based on three Oriental species. The sole Nearctic species is a representative of the nominative subgenus.
