Synonymy and Types
Neopyralis ronnai Brèthes, 1920, in Ronna, Chacaras e Quinaes 20(1): 18. 
Type locality: Rio Grande do Sul, Brazil.  Type deposition: type lost.

Cactoblastis ronnai, Heinrich, 1939, Proc. U.S. Natl. Mus. 86: 357.

Heinrich (1956) considered this species, reared from "spineless cactus," to be a probable synonym of C. cactorum.  However, because the type specimen is lost, its identity is unknown.  The rearing and collecting of Cactoblastis in southern Brazil may resolve the identity of this species.
