Type material.

NHMUK 1975342, lectotype; 1975343, two paralectotypes, Farris leg.; 1975344, three paralectotypes (Cuming coll.).

Remarks.

Pfeiffer (1857) described this taxon from Cuming’s collection, but did not state on how many specimens his description was based. In Pfeiffer (1859) he emendated his measurements and locality to "Long. 20 1/2-28, diam. 9-11 mill." resp. "Bolivia; in prov. Patas, Peru (Farris)". Subsequently, in Pfeiffer (1869 [1866-1869]) he only gave "Patas Perurvae [sic] (Farris)" as locality; the figured specimens by him belong to lot 1975344. His definition of this taxon might have been shifted over these years. The lot from Bolivia could not be traced in the NHMUK collection. The lectotype chosen by Breure (1978) was collected by Farris in Peru. Richardson (1995: 35) considered this taxon as junior subjective synonym of Bulimus nigropileatus Reeve, 1849. We tentatively regard this as a different-but evidently closely allied-species.

Current systematic position.

Bulimulidae , Bostryx stenacme (Pfeiffer, 1857).
