Dynamene sp.

Material examined.

Two stage 8 males. See the Suppl. materials 1 and 2.

Key morphological characters.

The bilobed pleotelsonic boss has a posteriorly-directed spine not seen in any other stage 8 males. The uropodal exopod is wide and the body markedly hirsute.

Habitat.

Known only from the stomach contents of a black scorpionfish Scorpaena porcus .

Geographical distribution.

Known only known from NW Aegean Sea.

Remarks.

Only two specimens have been found, both stage 8 males, and both from the stomach contents of a black scorpionfish, Scorpaena porcus . This could well be a new species of Dynamene , but more material is needed to confirm this. It may even be related to the hirsute specimens found in the Balearic Islands and the Greek island of Chios. The fish is known to be a bottom feeder in the Black Sea, close to where the specimen came from, which was in the NW Aegean, where it occurs at 20-40 m depth ( Başçïnar and Saǧlam 2009). Rafrafi-Nouira et al. (2016) examined the diet of Scorpaena porcus from waters off the coast of Tunisia, but the only isopods they found were listed as unidentified.
