Costaclis cubana (Bartsch, 1911): Bartsch (1947: 8, pl. 1, Fig. 7).

Type material. Holotype (herein examined): USNM 94290.

Type locality. Cuba: off Cuba, sta. 34; 1426 m; Rush leg.

Material examined. The holotype.

Remarks. Bartsch (1911) introduced the species in Aclis and later transferred it to Costaclis by the presence of strong axial ribs in the teleoconch (Bartsch 1947). Bouchet & Warén (1986) did not adopt the classification in Costaclis . The present species has a subcylindrical shell shape, a bulbous protoconch with less than 2.0 whorls and the absence of an umbilical fissure, which does not fit Aclis and Costaclis . Based on the previous shell features, a new classification in the genus Graphis is proposed here, despite lacking spiral cords at the lower half of each teleoconch whorl as in Graphis albida (Kanmacher, 1798) (= Turbo unicus Montagu, 1803), the type species of Graphis . Other species without spiral cords and with a very different protoconch morphology are currently considered in Graphis, for example, Graphis gracilis (Monterosato, 1874) (see Gofas et al. 2014: Fig. 7H, I, J, K).
