The Tumbes round stingray (Urobatis tumbesensis) is a little-known species of round ray, family Urolophidae, known only from two immature male specimens collected from estuarine waters at depths of 1–2 m, and a third specimen collected in 2006 near mangroves. Its range appears to be limited to coastal waters off Tumbes in northern Peru, where it is found partially buried in sand or mud. The larger of the original two specimens measured 40.
