We report two cases of parasitism by Riggia Szidat 1948 on freshwater fish of the genera Chaetostoma and Rhamdia from two rivers on the Upper Amazon of Ecuador, in the icthyogeographic areas of Alto Pastaza and Upano-Zamora. Riggia sp. was in both cases inside the abdominal cavity, forming large capsules between the peritoneum and pericardium.
