Abstract. Taxonomy and nomenclature of the genus Metaceronema Takahashi, 1955 are discussed. Metaceronema theae (Green, 1900), nom. resurr. and M. monticola (Wang, 1976), nom. resurr. are resurrected from synonymy with M. japonica (Maskell, 1897), the type species of the genus. Metaceronema theae is redescribed and illustrated. An identification key for the species M. japonica, M. theae, and M. monticola (Wang, 1976) is provided for the first time. Additionally, a new total drawing of M. japonica is provided to clarify the morphology of this species.
Key words: scale insects, morphology, taxonomy
