Remarks

• Systematics: This species is similar to R. saintpauliae (Williams), but differs by presence of multilocular disc pores on dorsum and venter of head. (Suh, et al., 2013) Ripersiella multiporifera differs also from R. hibisci in having multilocular disc pores on the head and single rows on the thorax and first two abdominal segments and two circuli, whilst in R. hibisci, though 0–2 circuli can be present, multilocular disc pores are absent on the head and those on the thorax and first two abdominal segments are represented by single ones (Jansen, 2008).
• Structure: Adults and nymphs oval elongate, white, 1-1.2 mm long. Slide-mounted characters: Anal lobes sclerotized on dorsum, each lobe bearing 1 long ventral seta and 2-3 long dorsal apical setae. Antennae 5-segmented. Eyes not present. Circuli present on abdominal segments II and III, shape truncate-conical, about same length as basal diameter. Multilocular disc pores numerous, present on dorsum in two rows at posterior edges of thoracic and abdominal segments and on venter at posterior edges of prothoracic and abdominal segments; a few present on venter of thorax; also distributed on dorsum and venter of head. Bitubular cerores of 2 distinct sizes present, each with wide truncate tubes. A large type present on dorsum only, usually distributed singly on margins, on midline and submarginal areas; a similar but smaller type of bitubular ceroris present on venter only, distributed in single transverse rows, mainly in middle of abdominal segments. Oral collar tubular ducts absent. (Suh, et al., 2013)
• Biology: This mealybug develops on roots of its host plants (Jansen, 2008),
• General Remarks: Description and illustration of adult female, first-instar nymph and second-instar female nympg by Jansen (2008).
