Remarks.

Pilsbry did not state on how many specimens his description was based, and gave no type locality as he described what he regarded as a colour variation only. His figure was a black and white copy of Reeve’s figure. Salvador and Cavallari (2013) have given this variety specific status and designated a specimen from MZSP as neotype. In doing so they disregarded material in the NHMUK (Reeve) and ANSP (Pilsbry), and their designation did not fulfil the requirements of Art. 75 ICZN. Salvador et al. (2014) corrected this issue and selected the figure of Reeve 1848 [1848-1850]: pl. 45 fig. 284 as lectotype, in accordance with Recommendation 74B ICZN. The specimens found are accompanied by a Reeve label, but cannot be matched exactly to his figure; they are considered as probable paralectotypes.

Current systematic position.
