Remarks. Rios (2009) recorded Cerithiopsis lata from Brazil based on a worn shell without protoconch but showing the typical color pattern of orange/brownish adapical and median spiral cords. This color pattern is often mentioned for C. lata in the literature about Caribbean material (e.g., Redfern 2001, 2013; Rolán et al. 2007), and is also present in the holotype ( Fig. 3A–B ), but with varying shades. The same color variation occurs in shells from Brazil, comprising those more like the holotype ( Fig. 3D ) to others with a darker brown color ( Fig. 3F–G ) or intermediary color shades ( Fig. 3D ). The dark shells were also illustrated by Redfern (2013) ( Bahamas) and Cecalupo & Perugia (2020) ( Martinique). Additionally, a slight variation in the shell shape was observed: Redfern (2013) illustrated slender shells (not as pupoid) with sharper nodules, a form that was also observed in some Brazilian shells ( Fig. 3E ).

Other remarkable distinguishing features of this species are the nodulose subperipheral cord ( Fig. 3I ), with the same coloration of the adapical spiral cord ( Fig. 3A–F ), and the fine striae on the base, below the basal cord ( Fig. 3I ). The protoconch is almost always broken off, but it was preserved in a few shells ( Fig. 3K–N ). Although slightly eroded, it is possible to recognize its subcylindrical shape ( Fig. 3L, N ), without sculpture, except for some microscopic granules close to the suture ( Fig. 3M ). This is similar to the description by Redfern (2013); Rolán et al. (2007) mentioned a protoconch with up to four smooth whorls.

Geographic and bathymetric distribution. Cerithiopsis lata is largely cited in the western Atlantic, including records from the Warm Temperate Northwest Atlantic and Tropical Northwestern Atlantic provinces, ranging from North Carolina to Venezuela, including all Caribbean region . In Brazil, it is herein confirmed from the Tropical Southwestern Atlantic and Warm Temperate Southwestern Atlantic Provinces , from Pernambuco to São Paulo states, including Abrolhos and Vitória Seamount. Littoral to 110 m.
