This paper presents the first report on the association between Dissodactylus crinitichelis Moreira, 1901 and Mellita quinquiesperforata (Leske, 1778) based on specimens found in Brazilian waters. Eighty-two specimens of sand dollars were collected and about 18 % harboured a total of 16 pea crabs. All crabs were found clinging underneath the oral surface of M. quinquiesperforata. The association found here suggests that the pinnotherid has a non-obligatory symbiotic association with M. quinquiesperforata.
