Cerithiopsis prieguei Rolán & Espinosa, 1996

( Fig. 20E–H )

Cerithiopsis prieguei Rolán & Espinosa, 1996: 142 , figs. 31–33, 44–46.

Cerithiopsis prieguei : Figueira & Pimenta (2008: 73, figs. 12–18); Rosenberg et al. (2009: 645, not figured); Rolán et al. (2012: 9, fig. 17); Redfern (2013: 141, fig. 404); Cecalupo & Perugia (2020: 44, pl. 21 figs. 2a–f, pl. 31 figs. 2a–d).

Type material. Holotype: MNCN 15.05 /17221.

Type locality. Cuba, Havana .

Material examined. Brazil: -- Rio de Janeiro state: 22°42ʹS, 40°40ʹW, 12 m, x/2005: MNRJ 32617 [1*p].

Remarks. The single shell studied here differs from the holotype of C. prieguei (illustrated in Rolán & Espinosa 1996 and Figueira & Pimenta 2008), by showing a late separation of the initially fused adapical and median spiral cords of the teleoconch on the fourth whorl ( Fig. 20E–F ). This can be also seen in one shell from the Bahamas ( Redfern 2013: fig. 404A) and another one from Espírito Santo ( Figueira & Pimenta 2008: fig. 13). In addition, the abapical spiral cord of the protoconch emerges later in the shell from Rio de Janeiro ( Fig. 20G ) and it is never as close to the adapical one as seen in the holotype. In these respects, the present shell from Brazil resembles the shells from the Bahamas ( Redfern 2013: fig. 404A) and Martinique ( Cecalupo & Perugia 2020: pl. 21, fig. 2f) more closely than the holotype

Geographic and bathymetric distribution. Disjunct distribution, in the Tropical Northwestern Atlantic Province ( Bahamas, Southeast Gulf of Mexico, Cuba, Martinique and Guadeloupe) and in the Tropical Southwestern Atlantic Province (Espírito Santo and Rio de Janeiro states). From 1 m to 90 m ( Cecalupo & Perugia 2020).
