Had to look pongid up, love it.
The term pongid refers to members of the genus Pongo - which embraces three species of Orangutan.
Orangutans are perhaps the most peace-loving of the family Hominidae (which includes the Gorillas, the Chimpanzees, and Humans), and so this term really shouldn't be applied to the violent and feral specimens described in the article.
