Diagnosis from Fu & Wilson 2010, p. 1005: "Head surface pitted; cervical groove straight, extending over dorsal margin of head and connecting medially; antennal notch deep, with posterior extension. Pleotelson ventral margin anterior to uropods 1.7–1.8 width of uropodal insertion; dorsal surface median ridge present; dorsal surface lateral ridges present, continuous with posterior apex; lateral uropodal ridge curving strongly and extending posteriorly from uropods on pleotelson margin. Posterior apex with one pair of robust setae (assumed on presence of setal sockets). Maxilliped epipod distal tip broadly pointed. Pereopod I subchelate; propodal palm convex. Uropod endopod subequal to protopod length." Line drawing from Fu & Wilson 2010, p. 1011: Identified by Dr. George D. F. Wilson, Saugatuck Natural History Laboratory, LLC. References: Fu et al.
