OCCURRENCE. — Middle Miocene: Austria (Baluk & Radwansky 1984). Late Miocene: Italy , Crete ( Moissette et al. 1993 ). Pliocene: Algeria (Haddadi-Hamdane 1996), Sicily ( Pouyet & Moissette 1992 ). Pleistocene: Spain ( Reguant 1969 ), Sicily , Umbria , central Italy ( Bizzarri et al. 2015 ). Recent: the present-day occurrence of this species is doubtful ( Cook 1965 ; Prenant & Bobin 1966 ). The nearest living species, R. doma , lives in tropical to subtropical waters of the Atlantic and Mediterranean, on sandy to muddy bottoms at depths of 10 to 370 m ( Cook 1965 ; Prenant & Bobin 1966 ). DESCRIPTION Lunulitiform colony. Frontal surface with alternating radial series of rhomboidal zooids, each bearing a distal vibraculum. The six cryptocystal denticles do not fuse in the middle of the opesia. The apical zone of the colony shows zooids covered by a calcified lamina. Basal surface depressed in the centre, displaying marked radial grooves and strong tubercles. REMARKS D. reussiana resembles very much Reussirella doma (d’Orbigny, 1851) to which it has been confused ( Prenant & Bobin 1966 ). According to Cook (1965) , the unfused cryptocystal denticles are especially characteristic of the western African Reussirella owenii (Gray, 1828).
