Scyllarus americanus – Holthuis, 1959a: 126, Suriname [27–53 m] – Not S. americanus (Smith) but S. chacei new species in Holthuis (1960: 152, "Under the name Scyllarus americanus (Smith) two species have currently been confused. The true Scyllarus americanus is known to inhabit the Atlantic coast of the U.S.A. from North Carolina to Florida, and the eastern Gulf of Mexico, including Cuba; it has been found in depths between 0 and 19 (usually between 3 and 12) fathoms. The other species, for which the name Scyllarus chacei is proposed here, has a far wider range, which extends from North Carolina to northeastern Brazil and throughout the Caribbean area; it is found in greater depths (usually 19 to 31 fathoms)"). — Guinot-Dumortier, 1960: 178, French Guiana [Sand, 105 m; probably not S. americanus but S. chacei].

Comment(s) on data
Holthuis (1960: 152) - Scyllarus chacei has been extensively described and well figured by Bouvier (1925, Mem. Mus. Comp. Zool. Harvard, 47(5): 448-450, PL 7, Fig 3), who identified his specimen as Scyllarus americanus, though he already noticed differences between it and a type specimen of Scyllarus americanus. Fenner A. Chace, Jr., Curator, Division of Marine Invertebrates, U.S. National Museum, was the first to draw my attention to the fact that the differences between this form and S. americanus are of a specific nature; it is therefore a great pleasure for me to dedicate this new species to him.
