Abstract
The genus Stebbingiella Marques-Junior & Senna, 2013 was recently established in the family Melphidippidae Stebbing, 1899. Stebbingiella does not fit this family concept for a number of reasons which include: antenna 1 accessory flagellum well developed; callynophore absent; maxilla 1 inner plate with apical robust setae; maxilla 2 inner plate without oblique setal row; coxae discontiguous; gnathopod 2 sexually dimorphic, enlarged in males; pleonites without dorsal carinae; epimera absent; uropodal rami linguiform or lanceolate; uropod 3 with short peduncle, rami longer than peduncle; telson dorsoventally thickened.
