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.
