Mainan

Large linguistic group of Native people of Peru. Can be found here 

Catholic Encyclopedia (1913)

A group of tribes constituting a distinct linguistic stock, the Mainan, ranging along the north bank of the Marañón.

Now included under  theCahuapanan languages.

Mainan and Mainas should redirect to http://en.wikipedia.org/wiki/Cahuapanan_languages

But they don't.  Even worse, a redirect goes to some Pokeman page.
