Type locality.

“Bolivia”.

Type material.

NHMUK 1975277, lectotype ( Breure 1978: 46).

Additional material.

NHMUK 1975278 (2), ZMB 112727 (2), paralectotypes.

Diagnosis.

Shell brownish coloured, on the last whorl a small, lighter coloured peripheral band is present, teleoconch sculptured with incrassate growth striae, thickened at irregular distances forming peculiar whitish longitudinal stripes, partly fading away at lower side of whorl, and crossed by shallow spiral lines.

Dimensions.

Shell height 51.5, diameter 22.0 mm.

Distribution.

Peru, Dept. Apurimac, Andahuaylas ( Morelet 1863); ibid., Abancay; Prov. Ayacucho, Ccarapa ( Breure 1978).?Bolivia.

Ecoregion.

Peruvian Yungas [NT0153].

Remarks.

Breure (1978: 46) has argued why the type locality might be based on a labelling error. Morelet (1863: 173) attributed juvenile specimens from Andahuaylas to this species. This species has not been recognised in material from southern Peru; the presumed occurrence in Bolivia remains problematic as we have not seen any trusted material from that country that could be assigned to this species.
