Thanks. I thought it might be Hypsiboas boans at first from the description. But as soon as I saw the pictures I knew it was a Trachycephalus species. Looking at pictures on-line they all pretty much looked the same to me, so I did a search on the ranges of three species, jordani, atlas, and nigromaculatus. Of those three, only one can be found in Ecuador, and that is Trachycephalus jordani.
I had to make another ID tonight as well. They place where I had purchased the pair of Phrynomantis bifasciatus had a frog that some one had brought in. They weren't sure what it was so they asked me to ID it. So I took a few pics with my cell phone and did a search upon returning home. When I first saw it it looked like some sort of Ranid, kind of like Rana muscosa but the eyes were all wrong. It has diamond-shaped pupils. The person who had brought it in said it was a goliath frog, so thats where I started my research. I discovered very quickly that it wasn't a "true" goliath frog, but something very close. I IDed it as a Conraua alleni, a very close relative. Its common name is Allen's slippery frog, but is sometimes imported in under the name of goliath frog. The "true" goliath frog is Conraua goliath and its huge. We have a perserved one on display at the Harvard University Museum of Natural History.
