The species now called Cangetta hartoghialis was described by Snellen from the above specimen taken in Neder Guinea (now Democratic Republic of Congo, Africa).

The next specimen named Cangetta rectilinea by Moore from Ceylon (now Sri Lanka), and later specimens from China and Australia, are currently thought to be the same species, but DNA evidence may yet prove they are different.
