I was just looking through the aqualog and noticed how much the xingu ray looks like the humerosa R 067 on page 96. Give it a look and let me now what you think? Or has someone allready determined what they are and I'm the last to know?

Are you thinking about the so called snow leopoard? There are quite a few rays in the xingu so you need to be more precise. ;)

The problem with the term "humersa" is the fact that it is used for describing several sp. species from peru and colombia. Peru flower, orbi, mosaic and so on.

In my mind it must be a part of the motoro complex and not the leopoldi complex as it only has one row of spines on the tail section.

I could be a "new" outbraker from the motoro speices just like p. scobina (the true secobina, not the one seen in the hobby) and p. orbignyi are.

I hope this answers your question. :)
 
The do have multiple rows of spines on the tail section or at least mine do. In the aqualog they do mention a difference in species R067 in the spines.
Your right humerosa is used to describe alot of species.

it would be very interesting if you could get a picture of that! :)
 
That is amazing! It means that they are part of the leopoldi complex. It also means that they are not directly related to the humersa types from colombia and peru.

I have seen tons of pics of younger rays and it never struck me that they would develop more rowes later, just like leos, scobinas ect does.

Just shows that you should never draw too many conculsions when looking at young rays. :)

Thx for the eye opener!
