[1] It was described as a new species in 1913 by Robert Charles Wroughton and Kathleen V. Ryley.

[2] Kerivoula crypta was traditionally considered synonymous with Kerivoula hardwickii (Hardwicke's woolly bat) until a 2018 genetic study revealed that K. hardwickii actually represented a species complex of bat species that appeared similar but differed genetically.

Unlike Hardwicke's woolly bat, individual hairs on its body are uniform in color (vs. bicolored).

[2] The cryptic woolly bat is native to southern India and Sria Lanka.

It is found at a range of elevations, encompassing both lowland and montane habitats.
