Etymology. The names are from Quechua, one of the major indigenous languages of Peru. " Chaska ñawi " (pronounced Chaska gnawi) means "Bright starry eyes" or "Ojos de lucero". This name was selected in a competition process organized by Caroline Chaboo and the ACA. The winner, Alison Pendrak, had studied abroad in Peru with School for Field Studies at the Villa Carmen Biological Station where C. nawi was found. She had learned the Quechua expression Chaska ñawi from the station's security guard Simeón Chura Quispe Simeon, to express her thrill of the Amazon starry night sky. In her submission she suggested that 'finding a new species is like finding a bright star amidst the darkness'.
