Caught in crab traps (~ 4 m deep) on the west coast of Barbados . Charybdis hellerii can be identified by two ocelli in the protogastric region of carapace, which fade slightly in preserved specimens; anterolateral margin with six sharp teeth; frontal margin with six sharp teeth with lateral pair reaching slightly past the inner orbital teeth; merus and carpus of swimming leg has a strong spine on posterior margin distally; propodus has row of spines on posterior margin (modified from Lemaitre 1995 ). The native distribution of Charybdis hellerii is in the Indo-Pacific region and it is invasive in the Western Atlantic and Mediterranean seas (Ahyong & Wilkens 2011; Dineen et al . 2001 ; Ferry et al . 2017 ; Negri et al . 2018 ). The origin of C . hellerii in the Lesser Antilles is unknown but, it is assumed that this species probably arrived as larvae in ballast water from the Mediterranean or any other localities in the western Atlantic where C . helleri is established ( Ferry et al . 2017 ). The mode of transportation of C . helleri to Barbados waters is unclear. FIGURE 17. Superfamily Portunoidea Rafinesque, 1815 , dorsal habitus: A, Charybdis hellerii (A.
