  Planococcus sosromarsonoi is closest to P. citri in having: (i) multilocular disc pores present on margins of abdominal segments even if only 1 or 2 present on each segment; (ii) multilocular disc pores on posterior edges of abdominal segments IV–VII forming more or less single rows; (iii) translucent pores present on anterior and posterior surfaces of hind coxa as well as on posterior surface of hind tibia; and (iv) oral rim tubular ducts forming a submarginal-to-marginal cluster on the marginal areas of abdominal segments III–VII. However, P. sosromarsonoi can be distinguished from P. citri by having (character states for P. citri are given in parenthesis): (i) dorsal oral collar tubular duct absent (present); (ii) a few oral collars on head and thorax (numerous); (iii) ratio of lengths of hind tibia + tarsus to hind trochanter + femur 0.68–1.00 (1.10–1.13); and (iv) oral rim tubular ducts forming a submarginal-to-marginal cluster on submarginal areas of abdominal segments III–VII with about 5–24 ducts (5–10 ducts). Planococcus sosromarsonoi also resembles P. nilgiricus in having no oral collar tubular ducts on dorsum. However, P. sosromarsonoi can be readily distinguished by having (character states for P. nilgiricus given in parenthesis): (i) multilocular disc-pores numerous, on venter of abdominal segments II and IX (multilocular disc-pores few, present on venter of abdominal segments IV‒IX only); (ii) ventral oral tubular ducts numerous, present mostly on marginal areas (dorsal oral rim tubular ducts few, present on submedian and median areas); and (iii) oral collars on head present (absent).

• Structure: Adult females secrete a delicate, powdery white wax that coats the dorsal side of their bodies. Slide-mounted adult female body broadly oval and membranous, with the largest specimen measuring 2.95 (2.50–2.95) mm in length and 1.73 (1.63–1.73) mm in width. Eyes located along margins, each approximately 50 μm wide, not connected to any simple pores. Antenna 8-segmented, measuring 0.60 mm in total length
• Biology: Living on roots and developing on stems close to the soil surface, and some on underside of leaves, frequently attended by unidentified ants.
• General Remarks: DetaIled description, photographs and illustration in Karkani, et al. 2025
