Specimens examined: Muoi in PM1 plot (aasl 66 m, lat. 21°54’ N, long. 104°38’ E), 1 ♀ on an unknown plant support, 17/V/2017; in P7 plot (aasl 66 m, lat. 21°54’51” N, long. 104°38’22” E), 1 ♀ on an unknown plant support, 21/VII/2017; in P16 plot (aasl 66 m, lat. 21°54’56” N, long. 104°38’46” E), 1 ♀ on Tephrosia candida (Fabaceae) , 22/VII/2017.

Remarks: This species was described from Hong-Kong by Swirski and Shechter (1961) collected on a wide range of plants and very common on citrus.

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 12 and compared with measurements obtained from specimens collected in other countries of Asia and Indian Ocean. Measurements obtained during this study agree well with most obtained from female specimens collected in other countries.
