Remarks.

This taxon was described as a subspecies of Quechua salteri (Sowerby III, 1890); Neubert and Janssen (2004) considered it as a distinct species. Upon comparison with both the types from Quechua salteri and Quechua olmosensis (Zilch, 1954), it appears very similar in its external morphology to the latter, and quite distinct to the former. Given the difference in size and the dislocation of the type locality, Weyrauch’s taxon is now considered as Quechua olmosensis maxima (stat. n.).
