Type material

Syntypes BMNH 1854.10. 4.466, 5 dd.

Type locality

" Saint­Domingue [ Dominican Republic]; Martinique; Saint­Thomas; Cuba " (by original designation).

Diagnosis

Shell small to medium (to 11 mm), slender, slightly curved, maximum diameter near oral aperture. Circular wrinkles in apical region, remainder of shell smooth. Apex simple, aperture slightly oblique. Section circular throughout.

Material examined

Syntypes of Gadila dominguensis   ; Lectotype of G. acus   USNM 95379 (designated by Henderson, 1920: 140); IBUFRJ 9649, sta C 65, 1 dd; IBUFRJ 9513, sta 16, 3 dd; IBUFRJ 9997, sta 48, 3 dd; IBUFRJ 12854, sta C 76, 30 dd.

Distribution

USA: Florida (Henderson 1920; Abbott 1974); Caribbean Sea: Porto Rico (Henderson 1920; Emerson 1952); Honduras; Guatemala; Belize (Henderson 1920); Colombia (Díaz & Puyana 1994); Cuba; St. Thomas; Martinique; Dominican Republic (Orbigny 1853; E merson 1952); Suriname (Altena 1971); Brazil: Amapá to Bahia (Scarabino 1975, 1994), Espírito Santo (this study). Living 53 to 103 m (Penna­Neme 1974), shells from shore to 100 m (this study).

Remarks

Henderson (1920: 141) already mentioned that Gadila acus   and G. dominguensis   were closely allied species but he retained both species until a comparison with the types could be done. As show in Figures 74 and 77 View FIGURES 74 – 89 , the types of G. dominguensis   and G. acus   , respectively, are not sufficiently different to justify these two species. The shared characteristics include general elongate slender form, equator situated immediately posterior of the anterior aperture and presence of circular wrinkles at the apical region. Gadila acus   is considered here a junior synonym of G. dominguensis   . Steiner and Kabat (2004) noted a questionable record of G. dominguensis   from the West African coast by Nicklès (1979: 64, fig. 21). Considering the shell profile of Nicklès´s sketch we agree with Steiner and Kabat (2004).
