Type locality.

[Bolivia] "non loin … de Tutulima" ( d’Orbigny 1837 [1834-1847]: 295).

Type material.

NHMUK 1854.12.4.120, lectotype ( Breure and Ablett 2011: 26).

Additional material.

NHMUK 1854.12.4.120 (3), paralectotypes.

Diagnosis.

Shell relatively large, slender, with irregularly spaced reddish-brown spots, sculptured with dense and fine granulation, suture descending in front, aperture oblique elongate-ovate, peristome simple.

Dimensions.

Shell height 66.5, diameter 25.9 mm.

Distribution.

Bolivia, Dept. Cochabamba, near Totolima.

Ecoregion.

Bolivian Yungas [NT0105].

Remarks.

This species is very similar to Plekocheilus (Eurytus) floccosus (Spix in Wagner, 1827), but is decidedly more slender. The reference to non-Bolivian localities ( Cousin 1887: 207) needs to be viewed with much suspicion as likely a misidentification may be involved.
