    Abstract

    This study reports the first record of candiru, Vandellia sp. parasitizing the freshwater stingray Potamotrygon scobina in the Amazon basin, Brazil. In April 2018, a specimen of Potamotrygon scobina was collected by bottom long-term using fish as bait during the monitoring program in the Xingu River. During a routine inspection, a Vandellia sp. was observed in the branchial slit of the Potamotrygon scobina specimen. The trichomycterid was collected and preserved in 10% formaldehyde followed by preservation in 70% ethanol. This study is the first to record this parasite associated on a stingray in Brazil.
