The new records provided here extend the geographic distribution know of nine hydromedusae species collected in the Laguna Madre, Tamaulipas, Mexico. The record of Phialella quadrata is the first one for the Western Atlantic Ocean, while Ectopleura dumortieri is registered for the first time in the Gulf of Mexico and Clytia folleata in the north of the same gulf. The geographic distribution of Bougainvillia superciliaris, Nemopsis bachei, Sarsia tubulosa and Clytia globosa is extended to a lower latitude, while Eirene tenuis and Octophialucium medium increase to a higher latitude.
