A commensal relationship between an unidentified species of Sphaeroceridae (Diptera) and <em>Cardisoma crassum</em> Smith (Crustacea: Gecarcinidae) from Cocos Island, Costa Rica, is reported for the first time. The pattern of infection is closely similar to that of <em>Drosophila</em> and <em>Lissocephala</em> (Diptera: Drosophilidae) found associated with other gecarcinids elsewhere. The Sphaeroceridae are apparently obligatorily exploiting an exclusive niche in the restricted environment, suggesting a genetical mechanism of adaptation for this particular group of Diptera, possibly derived and favored by geographical isolation.}, number={1}, journal={Revista de Biología Tropical}, author={Gómez P., Luis Diego}, year={1977}, month={Jul.}, pages={56–63} }
