Hope ya'll find this worthwhile. If you have the old one go ahead and delete it if you could. There isn't a great deal of of new material, but maybe just a bit of clarification as well as the addition of T. pachanoi. I might work on a more thorough map that has inclusions from other authors, but I think I need more than Book 4 of Ritter's, not to mention an English translation. And while your at it do a google search of "Chanchán river basin" and the first hit is a downloadable Word Doc that will provide you with a look at the evironment that has been associated with the first collections of T. pachanoi by westerners. (The HTML version doesn't have the photos.) Enjoy! ~Michael~
