Distribution.

Planococcus citri has a wide distribution in China and it is often difficult to separate from P. minor because of the variation in numbers of ventral oral collar tubular ducts. Material examined here is from Beijing, Fujian, Guangdong, Guangxi, Hainan, Hebei, Shanghai, Sichuan, Xinjiang, Yunnan.

Remarks.

Good descriptions and illustrations of the adult female can be found in Tu et al. (1988), Cox (1989), and Williams (2004).
