Genus Debroyerella gen. nov. Type species. Cheirimedon similis Thurston, 1974, by present designation. Included species. Debroyerella includes 3 species: D. fougneri (Walker, 1903); D. similis (Thurston, 1974); D. solidus (Andres, 1986). Etymology. Named for our friend Claude De Broyer in recognition of his life-long contribution to Antarctic amphipod biology. Gender feminine. Diagnostic description. Antenna 1 peduncle article 1 long (more than twice as long as broad); flagellum with weak 1 -field callynophore, or callynophore absent. Mandible molar columnar, with fully triturating oval surface; palp attached midway. Maxilliped outer plate very small, not reaching article 3 of palp. Gnathopod 1 subchelate, coxa large, almost as large as coxa 2, not tapering distally, anterior margin slightly concave; carpus compressed. Telson moderately cleft. Remarks. With a subchelate gnathopod 1, displaying a compressed carpus and large propodus, Debroyerella is very similar to Abyssorchomene De Broyer, 1984 and Koroga Holmes, 1908. Koroga differs in having a short (less than 1.5 × longer than broad) antenna 1 peduncle article 1, a well-developed 2 -field callynophore, a mandible molar that forms a setose tongue, and a notched telson. Species of Abyssorchomene also have a short antenna 1 peduncle article 1 and strong 2 -field callynophore. Distribution. Antarctica. Published as part of Lowry, J. K. & Kilgallen, N.
