Systematics: R. tropicasiaticus is very close to R. biggeri, described from the Solomon Islands, in possessing marginal multilocular disc pores on the venter of the head, thorax and abdomen, and dorsal large-type quinquelocular pores. However, in R. biggeri the multilocular disc pores are numerous on the head and thorax, and extend in a zone to the margins whilst in R. tropicasiaticus the marginal multilocular disc pores are few. The species is also similar to R. jabadiu by having large-type quinquelocular pores on the dorsum but they can be easily differentiated by the presence of multilocular disc pores on the ventral margin of the thorax .

Structure: Living adult female body is covered in the copious secretion of white wax and resembling a species of Icerya (Monophlebidae). In slide-mounted specimens, the body of the adult female is broadly oval, about 4.25 mm long and 2.75 mm wide. Antennae with 9 segments, legs well developed, long and slender. (Zarkani, et al., 2021)
Economic Importance: In the sapling stages, leaves of plants curl, turn yellow and die due to high infestation of the scales. (Zarkani, et al., 2021
