Described from Sumatra, and the synonym from India, this species has been recorded from Taiwan, as well as Bali, Singapore and Australia (Northern Territory). The record from Taiwan was based on about 40 specimens collected from grasses including Imperata cylindrica , but near Darwin this thrips was found living on the leaves of Ipomoea aquatica that was growing in shallow water. The genus Kazinothrips Bhatti was erected for this species together with one from North America, but was distinguished from Neohydatothrips solely by the 7-segmented antennae.

Recognition: Body dark brown, tergites II–IV paler medially, tergite I with dark antecostal ridge interrupted medially; all tarsi and tibiae yellow. Head with occipital carina close to eyes; ocellar triangle transversely striate; ocellar setae III lateral to triangle; three pairs of postocular setae, median pair not long and arising behind posterior ocelli. Pronotal sculpture mainly transverse with fine lines in between the main lines, blotch with posterior margin transverse. Metanotum with linear reticulation, many longitudinal lines between the main lines. Tergites II–V with no marginal comb medially, VI with comb weakly indicated. Sternites medially with neither discal microtrichia nor marginal microtrichia. Male sternites III–VII with large glandular area.
