  Phenacoccus miruku is similar to P. sisymbriifolium Granara de Willink 2007 and P. similis Granara de Willink 1983, but differs by lacking quinqelocular pores anterior to the mouthparts and translucent pores on the hind tibiae, and in the shape of the circulus. The molecular analysis does not support the generic designation of this new species in this study, which is based on adult female morphological characteristics. The analysis also indicated that P. miruku is not related to the type species of Phenacoccus, P. aceris (Signoret, 1875). Although this genus needs revision, we tentatively place the new species in Phenacoccus based on the current morphological classification.(Tanaka, Sasaki,, et al. 2022)

• Structure: Live adult female: Body elongate oval, yellowish, with a thin layer of white powdery wax, very short lateral filaments around entire body margin, and caudal filaments slightly longer and thicker than lateral filaments. At the oviposition stage, the adult female produces a rather loose ovisac of fine wax filaments and lays eggs in it. Slide-mounted adult female: Body elongate oval, 1.5–2.1 mm long and 0.8–1.2 mm wide; derm membranous; segmentation not well developed. Anal lobes evident but not prominent, dorsal and ventral surfaces of each lobe without sclerotised areas and ventral surface with long apical seta,. Antenna, with 8 or 9 segments (usually 9) and many flagellate setae,
