Type material.

ZMB 101827, two syntypes; ex Albers coll. No. 544, Warzewicz leg.

Remarks.

Albers did not state on how many specimens his description was based. The largest specimen found has the top damaged and a label ‘544’ glued on the last whorl behind the lip; moreover, the specimen has damage on the dorsal side of both (pen)ultimate whorls. The shells corresponds well to Pfeiffer’s figure, who stated "Aus der Albers’schen und meiner Sammlung". One other lot (ZMB 210505, two specimens) is labelled "Oberes Maranhon", from the same collector, but not originating from the Albers collection. Since there is no evidence that these specimens have been part of the original series and the locality does not match the published one, they are not considered as type material. This taxon is tentatively retained as a valid species.

Current systematic position.

Orthalicidae , Sultana (Metorthalicus) shuttleworthi (Albers, 1854).
