(1995) in an ecological species list as Exogone ovalis . In the Mediterranean also known from Lebanon ( Aguado and San Martin 2007 ) and Turkey ( Cinar et al. 2014 ), otherwise it has a circumtropical distribution (e.g. San Martin 1991 , Nogueira et al. 2004 , Boeggemann and Westheide 2004 ). The Eastern Mediterranean records make an occurrence of Exogone breviantennata in Greece likely, however, as it is very similar to the Mediterranean Exogone verugera ( Claparede , 1868), (distinguished from the latter mainly by the presence of a dorsal cirrus on the second chaetiger ( Aguado and San Martin 2007 )), additional specimens are needed to confirm its presence.
