Based on a study of holotype, Chrysomela javanica Thunberg, 1787 was proved to be a representative of the genus Tetraphyllus Castelnau & Brullé, 1831 and is therefore transferred from Chrysomelidae to Tenebrionidae. New combination Tetraphyllus javaniciff (Thunberg, 1787) (comb, nov.) is proposed. Tetraphyllus javanicus is redescribed and compared with its closest relative T. iridescens Ando, 1991. Colour photos of habitus of the type specimens of both taxa are presented. The checklist for all known species of the genus Tetraphyllus along with their known distribution is given.
