Remarks

This species is very similar to the Mediterranean species Exogone verugera (Claparède, 1868) but differs from it in having dorsal cirri on chaetiger 2 (lacking in E. verugera ) and a short proventricle (relatively long in E. verugera ).

Distribution

Exogone breviantennata was previously reported from the Pacific Ocean ( El Salvador, type locality), Australia, Red Sea (as Exogone ovalis ), western Atlantic Ocean and Mediterranean Sea ( Hartmann-Schröder 1960; Aguado and San Martín 2007). In the Mediterranean, it was first reported from the Lebanon on an encrusted cliff at 4–8 m ( Aguado and San Martín 2007). As it occurs in the Red Sea and Suez Canal, it could be considered as a Lessepsian migrant. It is new to the marine fauna of Turkey.
