Metaspidiotus Takagi 1957: 35. Type species: Aspidiotus stauntoniae Takahashi by original designation . junior synonym (discovered by Takagi1984: 3)

Systematics: This genus is very close to Aspidiotus Bouché, 1833 and Oceanaspidiotus Takagi in terms of pygidial lobes and pygidium, but can be distinguished by the form of the dorsal marginal setae occurring on L1 and L2 which are lanceolate, broadened and flattened, while these setae in the other two genera are simply thickened. (Wei & Zhou, 2016) Takagi (1957, 1969a) established Metaspidiotus as a separation from Aspidiotus, but differing from the latter in the lanceolate marginal setae of the pygidium. However, Takagi (1984) found that the presence of lanceolate setae on the bases of the second and third lobes is a common character to species of Octaspidiotus and species of Metaspidiotus, and therefore synonymized the latter with Octaspidiotus.
Structure: Body is oval to rounded; derm membranous except pygidium. Antennae with 1 seta. No trilocular pores associated to the spiracles. Pygidium. With 3-4 pairs of lobes, never bilobed. (Wei & Zhou, 2016)
