Craspedacusta cf. sowerbii Lankester, 1880 (Cnidaria: Hydrozoa: Limnomedusae): new record for the middle plateau region of the state of Rio Grande do Sul, Brazil

Abstract

This study reports a new record of Craspedacusta cf. sowerbii for the Municipality of Passo Fundo, located in the central plateau region of the State of Rio Grande do Sul. The C. cf. sowerbii specimens were collected in May 2010 in an artificial lake formed by the flooding of a former basaltic quarry. The lake is 665 m above sea level and its surface area measures around 25.000 m2. Its crystalline water is linked by the Miranda creek to the Passo Fundo River, part of the Uruguay River basin.
