ABSTRACT: Based on previously published records and original data, a checklist of the metazoan parasite fauna
reported in 26 species of native cichlids from Mexico is presented. The checklist contains 90 metazoan parasite
species, including 5 species of monogeneans, 19 adult trematodes, 27 metacercariae, 1 adult cestode, 3 larval
cestodes, 5 adult acanthocephalans, 2 cystacanths, 10 adult nematodes, 13 larval nematodes, 2 leeches, 2 pen-
tastomids, and 1 molluscan larva. It includes 140 new host parasite records for Mexico and records 13 species
for the first time.
KEY WORDS: Cichlasoma spp., Petenia splendida, helminths, pentastomids, leeches, molluscs.
At present, there is no checklist of metazoan tive cichlid fishes from Mexico, published in re-
