Comments. The name Clythra trinotata was published only in the ‘key part’ of Forsbergʼs publication. Although there is a short description, the name is associated also with the reference to homonymous Clythra sexnotata Fabricius, 1801: 35 . As explained in the introduction section, the name Clythra trinotata is treated as a substitute name and not as a description of a new species.

The Thunbergʼs collection contains two females labelled as type specimens of Clythra trinotata (type numbers 1757a, 1757b). These specimens are treated here as invalid types, since Clythra trinotata was proposed as a new substitute name for Clythra sexnotata Fabricius, 1801 and thus both names are objective synonyms and have the same name bearing type, in agreement with Article 72.7 ( ICZN 1999).

The homonymous Clythra sexnotata Fabricius, 1801 was substituted with Clythra bistrinotata Fabricius, 1803 by FABRICIUS (1803) and Clythra trinotata Forsberg, 1821 represents its unnecessary new substitute name.
