All species of the family Cryptoniscidae Kossmann, 1880 are endoparasitic or mesoparasitic, and can be found as direct parasites of decapods or as hyperparasites of rhizocephalan barnacles infesting decapod hosts. Females usually lose all body segmentation, lacking antennae, pereopods, oostegites and pleopods, and their bodies have two portions, an anterior portion that is embedded in the host cuticle and a posterior one that is external to the host. Males, on the other hand, are neotenous, and retain the morphology of the cryptoniscus larval stage. The genus\n                    <jats:italic>Zeuxokoma<\/jats:italic>\n                    Grygier, 1993 comprises six valid species, all of which are direct parasites of caridean shrimps in the Atlantic and Pacific Oceans.

We also comment on the morphology of the last embryonic stage, provide a map detailing the distribution of all currently valid species of\n                    <jats:italic>Zeuxokoma<\/jats:italic>\n                    , and construct a key based on the females to assist in the identification of species.
