Remarks

• Systematics: Most coccidologists follow McKenzie (1967), who placed species with 6 or more pairs of cerarii in Dysmicoccus, and species with 5 or fewer pairs of cerarii in TrionymusD. bunagaya, because morphological differences between this species and Trionymus okiensis Tanaka, 2018 are quite small. In the present study, D. bunagaya (with 8–13 pairs of cerarii) is placed in the genus Dysmicoccus.Dysmicoccus bunagaya. is similar to Trionymus okiensis in having a pair of frontal cerarii and oral-collar tubular ducts of 2 different sizes on the dorsal and ventral surfaces, and in using the same host plant (M. sinensis), but it differs from T. okiensis in having more than 8 pairs of cerarii (T. okiensis has fewer than 6 pairs). There is often considerable individual variation in this morphological character, and sometimes it cannot be used as a criterion for species separation; however, individuals showing intermediate morphology between the two species have not been observed
• Structure: Adult female feeds in the shoot apices of the host plant and secretes white powdery wax on all body surfaces. Slide-mounted adult female elongate oval, 3.5 (2.7–3.8) mm long and 1.1 (0.9–1.2) mm wide; derm membranous; segmentation relatively well-developed. Anal lobes distinct but not prominent, dorsal and ventral surfaces of each lobe with sclerotised area and ventral surface with long apical seta, 170–175 (140–183) μm long. Antenna 329–352 (281–385) μm long, with 7 or 8 segments and many flagellate setae. (Tanaka & Kamitani, 2021)
• Biology: Dysmicoccus bunagaya is frequently attended by exotic ant species, such as Technomyrmex brunneus Forel and Pheidole fervens Smith,
