Etymology.

This epithet is a noun in apposition. Kurulu, who lived near Jiwika, was a famous Dani leader in the 1960's. The district around Jiwika bears his name today. The species´ name refers both to the type locality and is a reference to the disappearing culture of the indigenous people of this area.
