On Laothoes (Crustacea, Amphipoda; Eusiridae) from the North Atlantic Ocean, with description of a new species

Detailed descriptions of Laothoes pallaschi n. sp. and of Laothoes macrocheir Oldevig, 1959 are given. The new species can be distinguished by the following characters: carpus and propodus of gnathopod 1 somewhat expanded, but these articles of gnathopod 2 elongate and very slender with very narrow palm, maxillipedal palp shorter than the outer plate, its article 3 about half the length of article 2, mandible with lacinia mobilis bulky. A proposed synonymization of L. macrocheir and Laothoes pacificus is rejected.
