Type locality Cuba, Atlantis sta. 2993, 23°24’N, 80°44’W, 1061 m GoogleMaps .

Previously known distribution. Florida, USA, to Alagoas state, Brazil, 275–2350 m ( Quinn, 1979; Barros, 2010).

New occurrence. Brazil, off Espírito Santo state, Abrolhos Slope.

Habitat. Quinn (1979) states that the species is more common in depths greater than 1000 m.

Material examined. Brazil: Espírito Santo: off São Mateus, Abrolhos Slope, 18°58’S, 37°49’W, MD55 sta. CB 76, 637 m, MNHN, 2 sh (27/v/1987); 19°01’S, 37°47’W, MD55 sta. CB79, 1500–1575 m, MNHN, 3 sh (28/ v/1987). Additional non-MD55 material: Mexico / Cuba: types.

Measurements. 5 whorls, H= 5.2 mm, D= 5.2 mm (largest specimen).

Remarks. The present material compares well to the types of L. pourtalesi . The species is readily diagnosable by its sculpture pattern (see Quinn 1979 for a full description). The present record greatly expands the species range, ca. 1,000 km to the south.
