Remarks

• Systematics: Morphology, cytology, and molecular biology analysis indicated K. yunnanensis and K. ruralis, the two Chinese endemic species, had significant differences from other Kerria species and confirmed that the lac commercial species in China was a different species from K. lacca. Evidence showed the commercial species in China was K. yunnanensis and this species was very different from K. chinensis, the commercial species of Thailand.(Chen, et al., 2011) K. yunnanensis is similar to K. chinensis (Mahdihassan) in having: (i) an elongated large body, (ii) an elongated and hispid supra-anal plate, and (iii) the brachia prominently elevated and tubular; it differs in (character states for K. chinensis in brackets): (i) canellar band absent, (ii) 29-39 ducts in each marginal duct cluster (57-62 ducts), and (iii) number of star pores near mouthparts 2 (2-19). (Ahmad, et al., 2013)
• Biology: Bi-voltine, summer (May-October) and winter (October-the next May).
• Economic Importance: This lac insect is the main commercial source of shellac resin in China. (Kondo & Gullan, 2022)
• General Remarks: Good description and illustration of the adult female given by Ou & Hong (1990). Redescription in English and illustration in Ahmad, et al., 2013.
