Diagnosis

Similar to M. sabinae sp. nov. with some exceptions: Ventral projections 1, 3–7 present in females and males; pleotelson L/W ratio in males subequal to females. In contrast to adult males of M. sabinae sp. nov., the fifth segment of the first antenna is distinctly shorter with only one type of aesthetasc. Pereopod VII length to body-length ratio in females less than in M. sabinae sp. nov. Male pleotelson subrectangular, pleuropodal constriction weakly expressed. Pleopod I lateral horns not projecting distally beyond medial lobes.

Etymology

Macrostylis amaliae sp. nov. is named after the grandmother of the first author’s wife, Amalie Blume.
