Abstract
A new species of amphipod, Megamphopus katagani sp. nov., is described from the sea of Marmara (Turkey). A key to the species of Megamphopus known from the North-East Atlantic, Mediterranean and associated seas is provided. During a recent survey in the Sea of Marmara (Fig. 1), amphipods were collected from the benthos. Amongst the samples was discovered a species of Megamphopus Norman, 1869 that could not be allocated to any known species. It is described here under the name Megamphopus katagani sp.nov. There are now five species (M. longi-cornis Chevreux, 1911; M. brevidactylus Myers, 1976, M. longidactylus Chevreux, 1925, M. cornutus Norman, 1869 and Megamphopus katagani sp. nov.) of Megamphopus known from the North-East Atlantic, Mediterraneanand associated seas. A key to these species is provided together with a description and figures of the new species.
