Remarks
Unlike Müller & Krapp (2009), we have never observed an absence of the lateral process tubercle in females.
Eurycyde raphiaster and E. kaiouti sp. nov. are very similar species that may have been mistaken in the past. After revising literature illustrations, we agree with the determinations of Müller & Krapp (2009) (at least the illustrated male), while Hedgpeth (1948) and Child (1992b) may have illustrated E. kaiouti rather than E. raphiaster.
Although the species is abundant in the Caribbean, this is its first record in Martinique. Our data suggest that it is less common in Martinique than E. clitellaria or E. kaiouti. The species was most often collected on the Caribbean coast, though a few specimens were sampled off Le Lorain and Presqu’Île de la Caravelle on the Atlantic coast.
Distribution
Bahamas, Gulf of Mexico, Caribbean, Cap Verde, Guyana and Senegal.
Depth range
0– 91 m.
