in the original description, four specimens were collected by the British naturalist and explorer Antwerp Edgar Pratt (1852-1924) during his sojourns in New Guinea with his collector sons Charles Henry Pratt (1886-1936) and Felix Thomas Biet Pratt (1891-1955). Pratt spent the months of May-June 1905 and December 1907-January 1908 near Fakfak on the Onin Peninsula (formerly Fakfak Peninsula), an extension of the Bomberai Peninsula in Dutch New Guinea (
