- Etymology: The specific epithet sundainsula is derived from the word Sunda which originally referred to a Hindu Kingdom in western Java existing from 669–1579. Sunda is now commonly used as an adjective associated with particular geographic features in the western regions of Southeast Asia associated with the South China Sea and its fringing continental areas. The Latin insula (singular) means island and sundainsula is an invariable noun in apposition in reference to this species being endemic to an island on the submerged Sunda Plains.
