Salmoneus setosus Manning & Chace, 1990 : non-ovigerous specimen (cl 3.4 mm) from Bocas del Toro, Panama (FLMNH UF 51922) [a, b]; ovigerous specimen (cl 4.0 mm) from Cozumel, Mexico (MNHN-IU-2019-2302) [c, d]; living shrimps in dorsal [a, c] and lateral [b, d] views. Photographs by Paulo P.G. Pachelle [a, b] and the author [c, d]. Remarks . Salmoneus setosus , although uncommon and rarely collected, is widely distributed in the tropical western and central Atlantic, with records from Mexico ( Yucatan and Cozumel), Cayman Islands (Little Cayman Island), Panama ( Bocas del Toro ), Brazil (Atol das Rocas, Fernando de Noronha, Trindade and Martin Vaz Archipelago) and Ascension Island (type-locality) ( Manning & Chace 1990 ; Anker 2007 , 2010a ; Anker et al. 2016 ; De Grave et al. 2017 ; present study). The species is herewith recorded from Panama ( Bocas del Toro ) and Cozumel Island in Mexico , based on recently collected material. The Cozumel specimen at cl 4.0 mm ( Fig. 6c, d ) is the largest specimen known so far; most of the other previously specimens reported have cl well under 3 mm ( Anker 2007 , 2010a ; Anker et al. 2016 ) or at most 3.0 mm, as for instance, the Bocas del Toro specimen ( Fig. 6a, b ). The colour pattern of S. setosus ranges from lemon-yellow in smaller individuals to bright orange-yellow in larger ones ( Fig. 6 ).
