Type locality.

[Peru] "republica Peruviana".

Type material.

NHMUK 1854.12.4.117, lectotype ( Breure and Ablett 2015: 25).

Diagnosis.

Shell with rather convex sides, height/diameter ratio 2.0, unicoloured light brown with a paler zone below the suture, peristome rather thick, simple.

Dimensions.

Shell height 51.9, diameter 25.1 mm.

Distribution.

Peru, Dept. Junín, "Prov. Huancayo" (Pilsbry 1895 [1895-1896]: 57); Dept. Huancavelica [?], Huaribamba (Philippi 1869).

Ecoregion.

Peruvian Yungas [NT0153].

Remarks.

Phillipi’s variety unicolor was described as an unbanded form from Huaribamba, which is found at ca. 3100 m elevation in Dept. Huancavelica or at ca. 4900 m in Dept. Junín. The former is adjacent to Prov. Huancayo mentioned by Pilsbry (1895 [1895-1896]). Philippi compared his taxon to Scholvienia brephoides ( d’Orbigny), which is also unicoloured. Philippi’s unfigured form-for which no dimensions were given and of which the type has not been located-has been treated as subspecies of the nominate form, but is herein considered as junior subjective synonym of d’Orbigny’s species.
