Remarks.

There are two further possible records of this species from Peru and Bolívia ( Ituarte et al. 2008; Ramírez et al. 2012), but the specimen figure by Ituarte et al. (2008: 83, text fig.), referred to as Systrophia (Entodina) aff. jekylli , is quite different from the type specimen figured by Simone (2006: 244, fig. 851B). The present specimens do compare well with the types; however, they lack the palatal tooth typical of the species ( Baker 1913). This could be simple morphological variation (intraspecific differences in dentition are common in pulmonate snails), represent juvenile or sub-adult specimens or, less likely, even be an indicative that the present material represents a new species. The present record greatly extends the species distribution, ca. 2000 km southeast.
