Distribution. Asia: India: Andaman Islands (Gupta, 1977a); Arunachal Pradesh (Gupta, 1987b); Assam (Gupta, 1977d); Bihar (Gupta & Nahar, 1981); Gujarat (Gupta, 1977c); Kerala (Gupta, 1980); Madhya Pradesh (Gupta, 1986); Meghalaya (Gupta, 1977d); Orissa (Gupta, 1977d); Pondicherry (Gupta, 1980); Punjab (Gupta, 1977c); Rajasthan (Gupta, 1977c); Tamil Nadu (Gupta, 1980); Uttar Pradesh (Gupta, 1982); West Bengal (Gupta, 1969, 1992).
Remarks. There is no marked difference between the dorsal setal measurements of our specimen and the original one (Table 8). The length of the ventrianal shield in our specimen (92 µm) is slightly longer than the earlier one (73 µm), apart from this other measurements agree with the available measurements of the former species.
Ecological notes. This species is recorded from the southern parts of West Bengal, in association with many economic crops and weeds of agri-horticultural importance, and was observed to feed on eriophyid mites and also Eotetranychus spp.
