In this study, we detail these structures, which have become essential for the separation of the species, and which have been used to establish the two new genera described herein. Another important aspect of urothoid taxonomy is that only a small number of structures have been illustrated and often the descriptions are short or poorly detailed, as in

only a few features were used, including: gnathopods 1 and 2 slender, subchelate, and similar; antenna 1 shorter than antenna 2; maxillipeds long and slender, with inner plate small; uropod 3 rami foliaceous; and telson deeply cleft. Only the uropod 3 with foliaceous rami is an exclusive feature of the genus, which makes it a weakly defined group. Many species displaying features described above were grouped into
