Figure 5

Material examined. 1 specimen, heavily damaged, ♂. On seagrass beds. 5 August 2014 (UANL-FCB-C20-8137), S2 (24°29.1833ʹ N, 097°41.9667ʹ W).

Distribution. North Carolina, south to Florida, through the Caribbean to Brazil ( d’Udekem d’Acoz 1997); in Mexico from Laguna Madre, Tamaulipas (this study [new record]) to Quintana Roo ( Escobar 1984, Román- Contreras 1988, Hernández et al. 1996, Rodríguez et al. 2000, Román-Contreras and Martínez-Mayén 2010, Hermoso-Salazar and Arvizu-Coyotzi 2015).

Previous records from Laguna Madre. None. New record.

Remarks. Previous records for the Gulf of Mexico in USA are inexistent, except those from Florida. Hippolyte curacaoensis is considered a junior synonym of H. obliquimanus ( d’Udekem d’Acoz 1997) . It differs from its closest relative reported for the area, H. zosteri cola , by having a rostrum usually armed with 3 or 4 strong teeth on dorsal margin, a strong lateral carina in proximal third of length, and the basal segment of antennular peduncle armed with 1–3 strong distolateral spines ( Figs. 5, 6A, B) ( Abele and Kim 1986; d’Udekem d’Acoz 1997). All these previous features were observed in the collected material.
