CapsalidaeBychowsky, B.E. (1957) Monogenetic Trematodes. Their systematic and phylogeny. Akad. Nauka. USSR. English translation by the American Institute of Biological Science, Washington. 509 pp. Yamaguti, S. (1963) Systema Helminthum IV. Monogenea and Aspidocotylea. London-New York, Interscience Publishers. 699 pp. is a family of monopisthocotylean monogeneans, which includes about 200 species.
The monophyly of the Capsalidae is supported by possession of accessory sclerites in the haptor (the posterior attachment organ), and was confirmed by molecular phylogeny. Their oncomiracidium (the free larva) is distinct from that of other families.
Capsalids are parasite on various organs of marine fish (teleosts and elasmobranchs), including skin, fins and gills. Several capsalid species, such a Neobenedenia spp. are pathogenic, especially on maricultured fish.
Included genera Genera as recognized in WorMs are listed below. Recent molecular analyses have shown that several genera, which were defined on morphological characters, are not monophyletic.
Menziesia and Nitzschia have their equivalent in the botanical nomenclature: Menziesia (a flowering plant) and Nitzschia (a diatom).
