03B92D24FFAC922CFF4627A701DFFE84.taxon	description	The weight of males ranged from 3 to 85 g (mean = 35.6 ± 26.1 g), while that of females ranged from 8 to 44 g (mean = 26.7 ± 18.7 g); the overall average was 30.3 ± 18.7 g. The relationship between carapace length and individual weight was described by the potential equation y = 0.0002 CL 3.1895, where y is the weight and CL is the carapace length in mm, with a determination coefficient (R 2) of 97 %. There was no statistically significant difference between sexes for the CL × weight relationship (p <0.05) (Fig. 3). The total length of males ranged from 51.4 to 137.6 mm, with an average of 103.0 ± 24.1 mm; females ranged from 75.6 mm to 124.1 mm, with an average of 102.5 ± 12.0 mm. The overall average was 102.7 ± 17.7 mm. The CL × CW relationship was the only one that showed no statistically significant difference between sexes (Tab. 1). The equations that describe each of these relationships, as well as each R ², are shown in Figure 4. Both sexes presented negative allometry for the CL × TL relationships and CL × CW and isometry for CL × AL. In other relationships, there were different growth patterns between males and females. Males presented positive allometry for most of relationships with third pereopod articles (CL × MerL, CL × CarL, CL × DacL), while females showed isometry. On the other hand, females presented isometry for CL × PL and CL × PH, and positive allometry for CL × AW, while male presented negative allometry for all these relationships. Males presented isometry for the CL × AmL and CL × AmW relationships and decreasing ratio Am L / W.

03B92D24FFAE922EFF4623EA07F2FA06.taxon	description	Male weight ranged from 11 to 39 g (mean = 26 ± 10.27 g), while female weight ranged from 1 to 11 g (average = 6.62 ± 3.92 g); the overall average was 16.31 ± 12.5 g. The relationships between carapace length and weight of males and females were described by the potential equations y = 0.0123 CL 2.0247 and y = 0.005 CL 2.29748, respectively, where y is the weight and CL is the carapace length in mm (Fig. 5). The total length of males ranged from 78.62 to 112.64 mm, with an average of 100.40 ± 24.26 mm. Female length ranged from 31.13 to 81.12 mm, with an average of 64.95 ± 23.15 mm. The overall average was 80.46 ± 23.44 mm. The CL × TL, CL × CW, and CL × DacL relationships showed no statistically significant differences between sexes (Tab. 3). The equations that describe each of these relationships, as well as each R ², are shown in Figure 6. Both sexes presented negative allometry for the CL × TL and CL × CW relationships and isometry for CL × ProL, CL × AL and CL × DacL. In other relationships, there were different growth patterns between males and females. Males presented positive allometry for CL × MerL and CL × CarL, while females presented negative allometry for the former and isometry for the second relationship. Females presented isometry for CL × PL, while males presented negative allometry for this relationship. Males presented negative allometry for the CL × AmL and CL × AmW relationships, and constant ratio Am L / W (Tab. 4, Fig. 6).	en	Oliveira Guilherme Souza Fabrício Lopes Carvalho Fernando Luis Mantelatto, Abner Carvalho-Batista Caio M.
