ABSTRACT. Considering the upgraded descriptive standards for monstrilloid copepods published by Grygier & Ohtsuka [1995], the type specimens of Mexican species were re-examined and redescribed. This study includes the redescription of three Mexican species of Cymbasoma Thompson, 1888, currently known as the most diverse genus of the copepod order Monstrilloida. The redescriptions were prepared following currently used standards, particularly in reference to the setal armature of the antennules and details of the cephalothorax integumental ornamentation. This revision reveals previously unnoticed characters; new comparisons of these species with recently described taxa are also provided.
KEY WORDS: semi-parasitic copepods, Cymbasoma, zooplankton, Caribbean Sea, taxonomy, redescription.
