Calliostoma caribbechinatum Landau, Van Dingenen & Ceulemans 2017: 123 View in CoL .

Type material. Holotype: USNM 214270 View Materials .

Type locality. Cuba, off Havana, Blake sta. 62, 146 m (Agassiz & Sigsbee leg., 1877) .

Previously known distribution. From Cuba to southern Brazil, live specimens down to 146 m ( Benkendorfer & Soares-Gomes, 2009; Rosenberg et al., 2009).

New occurrence. Abrolhos Slope, 60–295 m (shells only).

Habitat. Coralline and muddy bottoms.

Material examined. Brazil: Espírito Santo: off São Mateus, Abrolhos Slope, 18°59’S, 37°50’W, MD55 sta. DC 75, 295 m, MNHN, 1 sh (27/v/1987); Jaseur Seamount, 20°26’S, 36°17’W, MD55 sta. DC30, 60 m, MNHN, 2 sh (15/v/1987), 20°27’S, 35°54’W, MD55 sta. DC34, 54 m, MNHN, 5 sh (15/v/1987); Dogaressa Seamount, 20°50’S, 33°44’W, MD55 sta. DC43, 63 m, MNHN, 3 sh (17/v/1987). Rio de Janeiro: off Cabo de São Tomé, 21°37’S, 40°18’W, MD55 sta. DC15, 37 m, MNHN, 1 sh (10/v/1987). Additional non-MD55 material: Cuba: holotype.

Measurements. 6½–7 whorls, H= 4.9–6.1 mm, D= 4.5–5.5 mm (n=12).

Remarks. The name Calliostoma caribbechinatum was introduced by Landau et al. (2017) as a replacement for C. echinatum Dall, 1881 , a junior secondary homonym of C. echinatum ( Millet, 1865) , a fossil species from the Miocene of France. In his study about selected specimens from the MD55 expedition, Leal (1991) reported the occurrence of C. caribbechinatum (as C. echinatum Dall, 1881 ) on the islands of Trindade and Martim Vaz as well as the seamounts Jaseur, Davis, and Dogaressa, but did not mention the Abrolhos Slope (sta. DC75). This location is newly reported herein and it is also the deepest occurrence of the species known so far, expanding the previous maximum depth record from 220 m to 295 m. Even though the specimens examined here are exclusively empty shells, some are very well preserved, which at least means they were collected not too long after death and likely not far removed from their living area.
