A new ectoparasitic, colorless alga is reported here with the taxonomic description of a new genus and a new species as a member of the Cladophorales. This alga grows on shrimps from Japan. All of the vegetative cells are colorless, but the zoosporangia and the zoospores are furnished with many green chloroplasts.
