    Interest in paleolimnology has been growing steadily in México, as evidenced by a series of review articles that have recently been published. Work done by many researchers has provided valuable information about conditions in ancient environments. Although diatoms continue to be the most common dominants in Mexican studies, research shows that a other few species, particularly ostracods and sponge spicules, among others, have become significant contributors as indicators of environmental change, or paleolimnological markers. Unfortunately, this evidence cannot provide a complete record, and it is necessary to find new implements. Crysophycean cysts are common in diatomite deposits, but the lack of taxonomic detail and consistency offered by many of the earlier classification systems hindered the use of stomatocysts in paleolimnological studies, and they were simply lumped into one collective category and reported as a group. Although cyst morphology is very diverse, mature cysts may be smooth surfaced or ornamented with a variety of projecting or depressed structural elements. Consequently, fossil statospores or statocysts have been noted in many paleoecological studies, even though detailed investigations are currently rare in México. This paper is presented to establish a practical reference to the statocysts of El Arenal, Jalisco, México. An outcome of this research will hopefully be intensified interest in the use of stomatocysts as paleolimnological markers.

    Keyworks: crysophycean, stomatocysts, diatomite, lacustrine deposits, paleolimnological indicators.
