japes... that's S. jurupari though, Rio Mormon is one of the locations Martgarita Tours collects every year, definitely no leucosticta there. In the article they hint at two types in Peru and I think they mean strictly S. cf. jurupari type fish and when they refer to "jurupari-group fish that are delayed mouth brooders I think they refer to leucosticta. I can ask Lee just to be sure. I've talked to Devon a lot about collecting in Peru and he's only mentioned jurupari but he did say they don't collect all of the Rio Ucayali so maybe there is a chance.
