AGUILAR-ROSAS, Luis Ernesto; OCHOA-IZAGUIRRE, María Julia  y  AGUILAR-ROSAS, Raul. New records of Acetabularia schenckii and Acetabularia farlowii (Chlorophyta) from the Pacific coast of Mexico. Hidrobiológica [online]. 2006, vol.16, n.3, pp.267-270. ISSN 0188-8897.

The occurrence of Acetabularia schenckii Möbius (Polyphysaceae, Chlorophyta) is reported for the first time in the Mexican Pacific coast, out of its common distribution range along the Atlantic coast (Caribbean and Gulf of Mexico). Likewise, new distribution localities are reported for Acetabularia farlowii Solms-Laubach in the Mexican Pacific coast. Specimens were sampled from the intertidal zone to the 2 m depth in coastal lagoons from Sinaloa State, Mexico, during 2004 and 2005. A revision of specimens deposited in herbaria was carried out to determinate the geographic distribution of both species in the Mexican Pacific coast. The scarce records of Acetabularia could be related with inaccurate identifications, the small sizes of these species and to the lack of floristic studies in the study area.

Palabras llave : Acetabularia; Polyphysaceae; macroalgae; unicellular; Mexico; distribution.
