Remarks. Iphinoe douniae belongs to the I. trispinosa group. Adult males of both species have a single aesthetasc in the terminal article of the first antenna, a pair of perianal setae and a sternal process, like other species in the group. Distinctive characteristics of I. douniae include: plumose setae in the carpus of the second pereopod (a characteristic that is shared with the congeneric I. armata , which usually has an armated carina). Ledoyer (1965) wrongly reported that the plumose setae are on the merus instead of the carpus, as reported correctly by Corbera & Garcia-Rubies (1998). Moreover I. douniae differs from I. armata in having acuminate setae with variable size in the first joint of the uropod endopod, while in I. armata the distal seta in the first joint of uropod endopod is bigger than the others. Females are difficult to distinguish from other congenerics, which have 10 or more acuminate setae on the uropod peduncle: the seta formula is 10–12; 4–5+12.

Distribution and Ecology. Iphinoe douniae was reported from the western Mediterranean: Gulf of Lyons ( Ledoyer 1965, 1968, Massé 1972), Blanes ( Corbera 1995), Medes Islands ( Corbera & Garcia-Rubies 1998), Creixell beach ( San Vicente & Sorbe 1999) and Bay of Blanes ( Corbera et al. 2013). Moreover, it was observed in the eastern basin ( Katagan 1982): in the Sea of Marmara ( Bakir 2012), in the Izmir Bay, in the Aegean Sea, where it represents the most frequent species, occurring in 50% of the samples ( Doğan et al. 2016), and in the Levantine Sea ( Corbera & Galil 2016). Corbera and Garcia-Rubies (1998) hypothesized that I. douniae was misidentified as I. trispinosa , but since the latter is probably an exclusively Atlantic species, I. douniae is likely to be the vicariant species in the Mediterranean. Corbera & Garcia-Rubies (1998) stated that records of I. trispinosa at Banyuls, Collioure, Port-Vendres Argelés, Roses and Cala Mongó ( Fage, 1923, 1933, 1940) should be revised since they may refer to I. douniae .

The species has never been reported from the Italian coast, nor was it found in our samples.

Iphinoe douniae is an infralittoral species that was described for shallow terrigenous fine sands ( Massè 1972; Corbera & Garcia-Rubies 1995).
