Distribution. India (North-eastern region (Assam), Andaman Islands (Havelock) (Veenakumari & Mohanraj, 2007)); Bangladesh; Vietnam.

Prey/associated habitat. Collected on guava and jackfruit (label data); a predator of scales in Andamans (Veenakumari & Mohanraj 2007).

Notes. Hoàng (1980) described it from Vietnam. Veenakumari & Mohanraj (2007) mentioned it as present in Andaman Islands. Specimens from the Andamans and Assam were examined besides those in the collections of BMNH. It is more yellowish in coloration compared to the other Indian species of Novius and appears to have a limited distribution.
