Remarks.

Pfeiffer described this taxon from Cuming’s collection, but did not state on how many specimens his description was based. The specimen found corresponds to the shell height given by Pfeiffer. This is a case where the locality information provided by Cuming to the describer (viz. Pfeiffer) has been lost; the label ”Ecuador” on the frontside of the wooden tablet has been added in a later handwriting and may be erroneous.

Current systematic position.
