Ecological Risk Screening Summary - Potamotrygon tatianae (a stingray, no common name) - Uncertain Risk

Species that are considered uncertain risk need a more in-depth assessment beyond the Risk Summary to better define the species’ risk to U.S. environments.

Potamotrygon tatianae is a stingray native to the Madre de Dios River in southern Peru and northern Bolivia. P. tatianae was only recently recognized as a separate species from P. falkneri, so there is very little information regarding P. tatianae. This species is regulated in multiple States. The history of invasiveness for Potamotrygon tatianae is No Known Nonnative Population. There were no records of introduction. The overall climate match with the contiguous United States is low. Peninsular Florida had a medium to high climate match. Everywhere else had a low match. The climate match is based on a verbal description of the range because there were no georeferenced observations available. The certainty of this assessment is low due to lack of information. The overall risk assessment category is Uncertain.
