Type locality.

"Central America? (H. Cuming)".

Label.

"Merida / New Granada", taxon label in Pfeiffer’s handwriting. M.C. label style IV.

Dimensions.

"Long. 25, diam. 10 mill."; figured specimen herein H 25.2, D 11.24, W 6.6.

Type material.

NHMUK 1975480, lectotype; 1975481, two paralectotypes (Cuming coll.).

Remarks.

Pfeiffer based himself on material from Cuming’s collection, but did not state on how many specimens his description was based. The type locality was corrected to "Merida / Novae Granadae" in Pfeiffer 1853d: 347. The lectotype chosen by Breure (1979) corresponds to Reeve’s figure. This taxon has been misclassified as Leiostracus by Richardson (1995: 207). The material mentioned as Drymaeus studeri from Colombia by Linares and Vera (2012: 200), may only partially belong to that species. Unpublished data from Breure and Borrero strongly suggest that further morphological and molecular studies are needed to ascertain the status of this taxon and some taxa that have been associated with it in literature.

Current systematic position.

Bulimulidae , Drymaeus (Mesembrinus) studeri (Pfeiffer, 1847).
