First record for Brazil. Paraíba ( Rathbun 1900, as H. wurdemanni ).

Distribution. Western Atlantic: Bermuda to Brazil (Ceará, Paraíba and Espírito Santo, Atol das Rocas) ( Rathbun 1900, as H. wurdemanni ; Chace 1972; Christoffersen 1998; Coelho Filho 2006; present study) ( Fig. 16 View FIGURE 16 ). Central Atlantic: Ascension Island, St. Helena ( Manning & Chace 1990; De Grave et al. 2019). Eastern Atlantic: Cape Verde, São Tomé & Príncipe, Gabon ( Wirtz et al. 2016; present study).

Remarks. Lysmata moorei is a rare species in Brazil, previously reported from the country only twice ( Rathbun 1900, as H. wurdemanni ; Coelho Filho 2006). Among other Brazilian species, L. moorei can be readily recognised by the long accessory ramus of the antennule, consisting of seven or more free subdivisions ( Fig. 13E View FIGURE 13 ; Rathbun 1901: fig. 23a). Although L. moorei may represent a species complex ( Anker & Cox 2011; De Grave & Anker 2017), our material from Espírito Santo (MZUSP), Atol das Rocas (MNRJ material possibly lost in the fire in 2018, Dr. I. Cardoso, pers. comm.) and São Tomé (OUMNH) agrees well with the superficial description and illustrations provided by Rathbun (1901). The colour pattern of the eastern Atlantic specimens of L. moorei is herein illustrated for the first time ( Fig. 12 View FIGURE 12 ), also showing some intraspecific variation.
