Iphinoe acutirostris Ledoyer, 1965

Iphinoe acutirostris Ledoyer, 1965: 256, pl. 1 fig. 3A, 3B, pl.5 fig. 3, pl. 9 fig. 3, pl. 13 fig. 3, pl. 19 fig. 4–5; Ledoyer 1968: 175; Corbera & García-Rubies 1998: figs. 6; 7A; 7B.

Remarks. Iphinoe acutirostris is peculiar for the shape of its pseudorostrum: it is bifid in both sexes. Moreover, in males, the sternal process with 3–4 digits makes this species unmistakable.

Distribution and ecology. The species was known only in the north-western Mediterranean (Ledoyer 1965, 1968, Macquart-Moulin 1991, Corbera & García-Rubies 1998). The species has never been reported from the Italian coast, nor was it found in our samples.

Iphinoe acutirostris was reported in different environments: on the detritic bottoms of the Marseilles region at a depth of 35 m (Ledoyer 1965), as well as in Posidonia oceanica beds of the Medes Islands, at a depth of 11 m (Corbera & García-Rubies 1998).
