The genus Clypeasterophilus was originally erected to receive some members of Dissodactylus , including D.stebbingi ( Campos& Grippith1990) .According to these authors,species that belong to Clypeasterophilus are exclusive symbionts of irregular sand dolar echinoids of the genus Clypeaster spp. Sequences accession number (GenBank): CCDB 1382—16S ( MF490173 ), COI ( MF490077 ) ( Mantelatto et al. 2018a).
