Remarks. This is one of the most common phytoseiid species in Thailand. The females examined are slightly larger than reported in the original description (dorsal shield about 15% larger); concurrently, setae z5, S2 and S5 are on average about 15% longer. Our measurements are similar to those reported by Moraes et al. (2004a) for specimens from Sri Lanka.
