Fig. 6 ; Supplementary Table 1.2 Short description Large female (273 µm, n=1) with claw heteromorphy ( Fig. 6A ). On the dorsal side a median cirrus is placed close between the posterior edges of the secondary clavae ( Fig. 6B ). Edges of secondary clavae are also clearly visible on the ventral side ( Fig. 6C, C 2 ). Both external and internal claws are with accessory spines on each leg ( Fig. 6B, D ). The presence of gonopore and seminal receptacles allows us to be secure with sex determination. Remarks C. dissimilis is recognisable by the secondary clavae shape and median cirrus placed on the posterior end of secondary clavae. This representative exhibits claw heteromorphy and accessory spines as in the original description of Gomes-Júnior et al. (2020) .
