1F2D8790FFE7FFD7FF4AF5EC25F4FAFD.taxon	diagnosis	Diagnosis: Female body with head strongly distorted to left side and deeply buried in first pereomere. Barbula present, featuring two projections on each side. Eyes present. Pereopods uniform in size. Pleon distinctly segmented. Oostegites unequal in size. Males exhibit head and thorax partially fused. Eyes located on lateral edges of head. Dorsal pigmentation visible across body. Pleon segmented. For more details, see Markham (1975).	en	Nascimento, Ana Caroliny M., Lima, Daniel, Yamada, Priscilla O. F., Yamada, Fábio H., Pinheiro, Allysson P., Nascimento, Whandenson M.

1F2D8790FFE7FFD7FF4AF5EC25F4FAFD.taxon	discussion	Remarks: The specimens analyzed in the present study exhibit the same morphological characteristics as those described by Markham (1975) in the original description of A. clibanarii. Females (Figs. 2 A, B): body features a rounded elevation, with the head distorted to the left side of the body and deeply embedded in the first pereomere. The barbula displays two lateral projections on each side resembling small teeth. Pereopods are of similar size, but with smaller posterior dactyli. The pleon comprises six unequal pleomeres. Males (Fig. 2 C): the males analyzed are also morphologically consistent with the original description of A. clibanarii, showing an incompletely fused head and thorax. Eyes are present on the lateral edges of the head. All males examined exhibit a segmented pleon and dorsal pigmentation across the body. However, in male specimens of A. clibanarii from Paraíso Beach, the pigmentation consists of small, irregularly distributed black spots. In contrast, the allotype of A. clibanarii has small black dots (Markham 1975), appearing less pigmented than the males evaluated in this study.	en	Nascimento, Ana Caroliny M., Lima, Daniel, Yamada, Priscilla O.
