UNTIL RECENT COMPREHENSIVE REVISIONS OF TROPICAL FRESHWATER ZOOPLANKTON, TROPICAL DIVERSITY WAS CONSIDERED LOW, WITH MANY COSMOPOLITAN SPECIES. NEW EVIDENCE SUGGESTS THAT MOST OF THE FORMER COSMOPOLITAN SPECIES ARE IN FACT DISTINCT AND CLOSELY RELATED SPECIES WITH DISTRIBUTIONAL PATTERNS RESTRICTED TO A CONTINENT OR TO A PARTICULAR REGION. AMONG THE CLADOCERA, ALONA RACTANGULA G.O. SARS, 1862 OR Chydorus sphaericus WERE CONSIDERED AS WIDELY DISTRIBUTED SPECIES, BUT ARE IN FACT EXCLUSIVELY EUROPCAN. IN CALANOID COPEPODS, RESTRICTED DISTRIBUTIONAL PATTERNS ARE A WELL- KNOWN TENDENCY. IT WAS ONLY DURING THE PAST FEW YEARS THAT NEW SPECIES AND POSSIBLE ENDEMISMS HAVE BEEN DOCUMENTED FOR MEXICO; PREVIOUS SURVEYS WERE INITIATED IN THE TWENTIETH CENTURY, BUT WERE SPORADIC. THE AIM OF THIS WORK IS TO DETERMINE AND UPDATE THE STATUS OF KNOWLEDGE OF THE THREE MAIN ZOOPLANKTON GROUPS IN THIS COUNTRY AND TO OUTLINE THEIR BIOGEOGRAPHICAL AFFINITIES WITHIN THE AMERICAS.
