Remarks.

The locality on the label is more specific than the published type locality; “Santiago” possibly refers to a locality SW Pasto, just north of Tulcán across the Colmbian-Ecuadorian border. The top of the shell is slightly damaged, but it agrees otherwise well with Dunker’s figures. His figures shows the vertical sculpture too pronounced and may thus be misleading. The shell identified as Plekocheilus (Eurytus) lugubris by Borrero and Breure (2011: 49, figs 15K-M) does not correspond to this species, but is a hitherto unknown species. However, their reclassification of Dunker’s taxon with Plekocheilus (Eurytus) is supported.

Current systematic position.

Amphibulimidae , Plekocheilus (Eurytus) lugubris (Dunker, 1882).
