MENDOZA-GONZALEZ, A. Catalina  e  MATEO-CID, Luz Elena. The genus Dictyopteris J.V. Lamouroux (Dictyotales, Phaeophyceae) in the shores of Mexico. Hidrobiológica [online]. 2005, vol.15, n.1, pp.43-63. ISSN 0188-8897.

An extensive bibliographic revision of the genus Dictyopteris (Dictyotales, Phaeophyceae) previously recorded in the Mexico's shores was realizated. We checked herbarium's specimens that are housed in different herbaria for getting the information on this genus. Also, some samples of Dictyopteris were carried out in sixty localities from Ensenada, Baja California to Bahia San Agustin, Oaxaca in the Pacific coast and from Ciudad Madero, Tamaulipas to Banco Chinchorro, Quintana Roo at Atlantic coast of Mexico from 1988 to 2003. Analysis of this information showed us that this genus contains eight species; moreover, D. delicatula J.V. Lamouroux and D. polypodioides (De Candolle) J.V. Lamouroux are distributed for both coasts at the Pacific and Atlantic shores of Mexico. Reproductive structures of Dictyopteris jamaicensis W. Taylor are described for first time and Dictyopteris jolyana Oliveira and Furtado is a new record from the Mexican Caribbean. Morphological descriptions, cytology, reproductive stage, drawings, keys for determination, specimen's examinated and distinctive characteristics of each taxon are included
