Remarks: This species was described from specimens collected on Heterosmilax gaudichaudiana and Urena lobata in Victoria Mount Forest, Hong Kong Island, Hong Kong.

Although species of the genus Phytoseius are considered to belong to the type III (polyphagous generalist predators) of McMurtry and Croft (1997) and McMurtry et al. (2013), its specific biology is totally unknown.

This is the first mention of that species in Vietnam.

Measurements of specimens collected during this study are provided in table 13 for females and males and compared with measurements obtained from specimens collected in other countries of Asia and Africa.

Measurements obtained agree well with most of those obtained previously, with slightly shorter dimensions, especially in male specimens.
