Description and some ecological aspects of two species of Eudactylina (E. rhinabati and E. turgipes) were found parasitic on two specimens of Glaucostegus granulatus and seven of Gymnura poecilura during the period from January 2011 till June 2012 from the north west of the Arabian Gulf (Latitudes 48° 44? to 48° 46?; longitude 29° 46? to 29° 47?). The prevalence of infection and the mean intensity of infection of E. rhinabati and E. turgipes was 40 %, 4.5 and 28.5, 2 respectively. The present finding of E. rhinobati on the gills of G. granulatus represents its first record in fishes of the Arabian Gulf, and its second occurrence in the World, while the finding of E. turgipes  on the gills of G. poecilura in the present study represents a new host record and a new geographical distribution .
