Remarks

• Systematics: <>Saccharicoccus chinensisis similar to S. isfarensis in the distribution of tubular ducts and multilocular disc pores, but it differs from the latter by the following features (condition of S. isfarensis given in parenthesis): (i) translucent pores present on hind coxa (pores absent from hind coxa); (ii) minute pores mostly situated on derm medial and anterior to hind coxa (minute pores concentrated lateral and posterior to hind coxa, as far posteriorly as abdominal segment II. It also resembles Palmicultor lumpurensis (Takahashi) in possessing minute pores in the derm surrounding each hind coxa, but differs from the latter by the following features (condition of P. lumpurensis given in parentheses): (i) anterior edge of clypeolabral shield without internal, transversely oblong extension (anterior edge of clypeolabral shield with internal, transversely oblong extension); (ii) cerarii numbering 2 pairs only (cerarii numbering 2–7 pairs); (iii) large type of tubular duct about the same width as a trilocular pore, longer than wide (large type of tubular duct much wider than a trilocular pore, but narrower than a multilocular pore, each about as long as wide or sometimes slightly shorter). In S. chinensis, the number of tubular ducts and multilocular pores vary between individuals. Some specimens have only a small number of ducts and pores in the anterior part of the body, in other specimens these ducts and pores can be much more numerous. (Zhang, et al., 2018) The pairwise genetic divergences (by K2P distance) in COI is 2.20% within S. chinensis, 9.17–13.03% between S. chinensisand the other two Saccharicoccus species, and 11.86–12.10% with Palmicultor lumpurensis; so the molecular data confirms S. chinensis as a distinct species. (Zhang, et al., 2018)
• Structure: Adult female elongate, covered in white mealy wax, with caudal filaments present, each filament longer than posterior-most abdominal segment; body contents mostly pinkishgray. (Zhang, et al., 2018)
• Biology: Living under the leaf sheaths of its host plants.
• General Remarks: Detailed description, illustration and photographs in Zhang, Wu & Wu, 2018.
