Peristoreus viridipennis is a species of true weevil.

[1] It is associated with plants of the genus Muehlenbeckia.

[2] P. viridipennis was originally named Erirhinus viridipennis by Broun in 1880.

[3] Then, in 1926, Marshall described a new genus called Dorytomodes, into which he provisionally transferred all species placed by Broun in Erirrhinus [=Erirhinus].

[4] Dorytomodes was subsequently sunk as a synonym of Peristoreus by Edwin S. ("Ted") Gourlay in 1950.
