Remarks. BOHEMAN (1855) explicitly described Coptocycla nobiliata from a single specimen. I also assume that Coptocycla briseis was based on a single specimen according to the original description, due to its not fully sclerotized elytra and unusual colouration.

SPAETH (1926) studied a specimen compared with the type of C. briseis by G. E. Bryant and concluded that it is close to C. nobiliata , differing only in the sparser punctation of elytra. I have studied the holotype of C. briseis as well as the specimen compared by Bryant and both are teneral and not fully sclerotized. As a result, the punctation of elytra artificially appears sparser and finer than in C. nobiliata . Otherwise both taxa are identical and lead me to synonymize C. briseis with the latter species.

Distribution. Brazil: Rio de Janeiro ( FLINTE et al. 2009).
