Etymology. This species is named after the Italian anthropologist Lidio Cipriani who was among the first to study the Onge tribe of Little Andaman from where the type specimens were collected. The name is treated as a noun in the genitive case.

Diagnosis. This species is closer to B. chakora sp. n. and the diagnosis is mentioned under the latter.
