Remarks

Radula pallens is a widespread neotropical species, that has been misunderstood in the past and was considered endemic to Jamaica (Gradstein in press). Radula subsimplex is a phenotype of R. pallens with lobule margins not sinuate. Several Caribbean species of Radula described by Castle (1959) in the section “ Dichotomae ”, such as R. obovata Castle and R. varilobula Castle, are probably further synonyms of R. pallens .
