Abstract

VAN DER HEIDEN, Albert M.; RUIZ-GUERRERO, Marcela  and  PLASCENCIA-GONZALEZ, Héctor G.. The ringtail tonguefish, Symphurus ocellaris, a new addition to the marine fish fauna of Mexico (Cynoglossidae, Pleuronectiformes). Rev. Mex. Biodiv. [online]. 2011, vol.82, n.1, pp.305-310. ISSN 2007-8706.

Eleven specimens of the ringtail tonguefish, Symphurus ocellaris Munroe and Robertson, 2005, were obtained from off the coasts of Chiapas and Colima, Mexico. Previously, this species was known only from the 2 type specimens collected off the Pacific coast of Panama. Our finding constitutes the first record of the species in Mexico and the second known occurrence of the species. The northern distribution limit of S. ocellaris is now extended by 11.5 degrees latitude or about 3 400 km of the eastern Pacific coastline, from Panama to Colima, Mexico.

Keywords : range extension; geographical distribution; eastern Pacific; Panama; Mexico.
