Comment 
EtymologyThe specific epithet caetê is a Tupi indigenous name, here employed as a noun in apposition alluding to the Atlantic Rainforest remnants (caá = forest; etê = true) where A. caete was found. The Tupi word caetê is also the denomination for the extinct anthropophagous group of Brazilian Indians native to the region of the type locality. Portuguese colonizers later exterminated the “Caetés” after the natives captured and devoured Dom Pero Fernandes Sardinha, first bishop of Brazil on July 16 1556.
