Comment: Carlos Lira (mail April, 2015) kindly pointed us that at least photo of specimen MNHN-IU-2013-5133, posted on the internet in the database of Legall & Poupin (2016), is not A. ordwayi but probably a Cronius sp. Instead.

Comment(s) on data
Check all photo from det. Besse 2013, cf. mail C. Lira, April 2015 - I think that there is another trouble with the pictures of Achelous ordwayi. If you look at the teeth of the anterolateral margin of carapace of the last picture you can count 9 teeth,8 of them of the same size (and its ok) and the teeth of the front are deeply separate of the internal orbital tooth, but if you see the same structures at the previous one, you can count 9 teeth, but the first 8 area alternatelly large and small, and the front is quite different. I think that they are pictures of A. ordwayi and Cronius in the page
