Cerithiopsis iota (C. B. Adams, 1845) View in CoL and Cerithiopsis cynthiae Bartsch, 1911

Cerithiopsis iota View in CoL , described from Jamaica, was considered by Rios (1985, 1994, 2009) as a synonym of C. gemmulosa View in CoL (an opinion not followed in the literature). Absalão & Pimenta (2005) and Santos et al. (2007) recorded C. iota View in CoL from eastern Brazil.

Cerithiopsis cynthiae , described from Bermuda, was first recorded from Brazil by Rios (2009), based on a micrograph of a shell that resembles C. flava View in CoL with a broken protoconch.

Odé (1989) considered C. iota as the “central form” of a complex including C. iota , C. flava , and C. pesa . De Jong & Coomans (1988) considered it as a senior synonym of C. cynthiae . Rolán et al. (2007) considered it as a nomen dubium, but it as a synonym of C. flava (however, the illustrations of the holotype of C. flava in Rolán et al. 2007 (Pl. XII, fig. 108) actually is the holotype of C. albovittata .

Cerithiopsis iota View in CoL is considered an available name in MolluscaBase (2023) and a senior synonym of C. cynthiae according to De Jong & Coomans (1988). The type is very eroded ( Clench & Turner, 1950), although it is indeed very similar to the syntypes of C. cynthiae . Its identity and relationships cannot be evaluated until new material from the type locality is obtained. For those reasons, and considering the images provided by Rios (1985, 2009) in comparison to the types, we believe that the records of C. iota View in CoL and C. cynthiae from Brazil cannot be considered reliable.
