Type locality.

[Peru] "Cuzco, Bolivia".

Type material.

NHMUK 1975148, lectotype ( Breure 1978).

Additional material.

NHMUK 1975149 (1), paralectotype.

Diagnosis.

Shell with brownish groundcolour and one, white peripheral band, sculptured with narrow, longitudinal, irregularly thickened, densely placed rib-like striae (Fig. 59D).

Dimensions.

Shell height 35.5, diameter 16.5 mm.

Distribution.

Peru, Dept. Amazonas, Yambrasbamba (NHMUK 1928.12.6.77-93); Dept. Junín, near Tarma and La Oroya.

Remarks.

Weyrauch (1964: 46) argued that the type locality is probably in error; this species has not been re-found in the Cuzco area nor in Bolivia, and neither has any similar species. The taxa from Philippi and Pilsbry were described from "ad Oroya haud procul ab oppido Tarma", respectively [La] Oroya. The specimens on which Strebel based his Scholvienia jaspidea forma minor were collected at “Quimia”, which might be a misspelling for Quenua at ca. 4000 m in the same general area. The shells figured fit into the variation shown by Scholvienia alutacea (Reeve). We found a lot from Yambrasbamba, north of Chachapoyas, which we tentatively refer to this species. Further studies should clarify the distribution and systematic position of Reeve’s taxon.
