Remarks

• Systematics: Ferrisia kaki most closely resembles F. cristinae in having few ventral oral-collar tubular ducts on the abdominal submargin (not those in posterior marginal clusters), and often with a circular discoidal pore in the sclerotized rim of the duct or on nearby derm. However, F. kaki differs from F. cristinae in having: (i) multilocular disc pores only on abdominal segments VII and VIII+IX (VI–VIII+IX in F. cristinae) and (ii) 87–99 enlarged tubular ducts on the dorsum (95–113 in F. cristinae). F. kaki is also similar to F. terani in having a small number of multilocular disc pores and a slender body shape, but F. kaki can be readily distinguished from F. terani in having: (i) two sizes of oral collar tubular ducts on the venter (only one size in F. terani); (ii) enlarged tubular ducts with a minute discoidal pore touching the sclerotized rim of duct opening. (Pacheco, et al., 2016)
• Structure: Ferrisia kaki is characterized by the following combination of features: (i) ventral oral-collar tubular ducts of two sizes, smaller ducts present singly or in segmental clusters on the body margin, on the last two or three abdominal segments; (ii) minute discoidal pores on the sclerotized area of enlarged tubular ducts, almost always touching the sclerotized duct rim, and (iii) both anterior and posterior pairs of ostioles present and well-developed. (Pacheco, et al., 2016)
• General Remarks: Detailed description and illustration in Pacheco, et al., 2016.
