Comments. The only reference to Clythra sexpunctata Forsberg, 1821 wasfound in LACOR- DAIRE (1848), who mistakenly listed it as a simple reference of Clytra sexpunctata Olivier, 1808 (now synonym of Tituboea biguttata ). However, FORSBERG (1821a) did not associate his description with any reference and it must be accepted as a validly described taxon. It is conspecific with Tituboea biguttata and I propose to synonymize the two taxa.
