Remarks. Cerithiopsis rabilleri was described based on a single shell from Martinique. The original description mentioned the presence of minute grains in the suture of the protoconch. Although it is not visible in the printed plate of that species by Cecalupo & Perugia (2020), examination of high-resolution image of the holotype in the MNHN molluscs collection dataset (https://www.gbif.org/occurrence/2860632301) reveals the existence of very short axial threads in the suture of the somewhat eroded protoconch, which are also present in some shells from Brazil ( Fig. 7H–J View FIGURE 7 ), depending on the preservational condition of the protoconch.

Cerithiopsis rabilleri is similar to Cerithiopsis gordaensis Rolán & Fernández-Garcés, 2010 , from Cuba. Both have similar teleoconch shape and sculpture. The minor differences are in the protoconch: C. gordaensis has 2.5–3 protoconch whorls, while in Cerithiopsis rabilleri has up to 5 whorls ( Fig. 7G View FIGURE 7 ); regarding other aspects of the protoconch, such as the smooth convex whorls, they are nearly identical.

Geographic and bathymetric distribution. Disjunct distribution, in the Tropical Northwestern Atlantic Province ( Martinique) and in the Tropical Southwestern Atlantic Province (Bahia and Rio de Janeiro states). From 2 m to 110 m.
