Remarks.

Strebel described his species on the basis of material supplied by Rolle. There are several places with the name Huancabamba throughout Peru, but Rolle supplied more often material from the Chanchamayo region. Therefore it is assumed this material originated from (Tingo de) Huanacabamba in Dept. Pasco, which is at ca. 1870 m altitude in the Chanchamayo region. Strebel (1910: 26) remarked that, when the shells were held against bright backlight, one sees one, or more often two, spiral bands that are lighter than the groundcolour. This hints at a possible close relationship of this taxon with Scholvienia bifasciata (Philippi, 1845) or Scholvienia iserni (Philippi, 1867). The spiral banding visible in Strebel’s original figure (Fig. 65I) may be due to a growth anomaly.
