Specimens examined: Muoi, in P4 plot (aasl 66 m, lat. 21°54’41” N, long. 104°38’7” E), 1 ♀ on Styrax tonkinensis (Styracaceae) , 12/V/2017; in P6 plot (aasl 66 m, lat. 21°54’55” N, long. 104°38’22” E), 1 ♀ on Curculigo orchioides (Hypoxidaceae) , 15/V/2017; in P4 plot (aasl 66 m, lat. 21°54’41” N, long. 104°38’7” E), 1 ♀ on Xanthium stumarium (Asteraceae) , 18/VII/2017; in P6 plot (aasl 66 m, lat. 21°54’55” N, long. 104°38’22” E), 1 ♀ on X. stumarium (Asteraceae) , 20/VII/2017.

Remarks: This species is widely distributed in tropical and subtropical areas in South America, Africa and Asia. It and other members of the genus belong to the large polyphagous generalist group, type III ( McMurtry & Croft 1997; McMurtry et al. 2013). Navasero and Navasero (2016) have studied the life history of P. orientalis on the broad mite, Polyphagotarsonemus latus (Banks) , as prey. The authors reported high predation rates on P. latus eggs, suggesting its potential use against this pest.

This species has been collected before in Vietnam by Nguyen et al. (2016). Exact indications of locations were provided in this paper but without providing measurements of collected specimens. Measurements from this study are provided in the table 4 and compared with those obtained from specimens collected in other countries of Asia and Indian Ocean.

Measurements obtained with this study agree well with most obtained from female specimens collected in other countries, especially with measurements of specimens from Hong Kong and La Réunion Island.
