The occurrence of the euteliid moth Targalla delatrix (Guenée, 1852) in mainland Taiwan and Kinmen is confirmed through genitalia examination with reporting its newly recorded hostplants as Syzygium acuminatissimum (Blume) DC. and agriculturally important Mangifera indica L. (mango), respectively. The latter represents the first hostplant of Targalla recording on the plant family Anacardiaceae. Further identification for the purpose of mango quarantine should be more careful since the larvae of T. delatrix and Penicillaria jocosatrix Guenée, 1852, that both feeding on mango, are very similar in external appearance. In addition, the Chinese vernacular name of the comparable species, T. silvicosta Watabiki and Yoshimatsu 2014, is newly proposed.
