Seemingly related to the Tlapanec proper were the Yopi (Yope) people, whose territory in the vicinity of Acapulco was called
Yopitzinco. The Yopi, being formidable warriors, were never conquered by the
Aztec Empire and remained an independent enclave surrounded by the Aztecs, yet were invited to the coronations of Mexica rulers in
Tenochtitlan, where they were given gifts. There may have been some cultural differences with the Tlapanec proper, such as Yopi culture having a greater emphasis on hunting with the bow and arrow and not wearing clothing until marriage (and even then, only palm leaves and deerskins). The Yopi worshipped
Xipe Totec and perhaps are responsible for bringing this cult to Tenochtitlan. Although divorce was permitted, the Yopi punished adultery by the offended spouse biting off the offender's nose upon the first infraction, and by stoning to death on the second infraction. ==References==
