Now that you know it's not S. acuticeps go here to find out whether it's a true S. jurupari or S. leucosticta. http://hometown.aol.com/pmchefalo/RioBranco.htm
It's not too hard to tell the difference really. Jurupari have solid bars on the face whereas leucosticta have spots and spangles.
Jurupari are harder to find but IMO leucosticta are prettier.
