Type material.

NHMUK 1907.11.21.32, lectotype and one paralectotype (da Costa coll.).

Remarks.

da Costa did not state on how many specimens his description was based. A lectotype was designated by Breure (1979); the paralectotype is slightly damaged at the palatal lip. The current systematic position follows Richardson (1995: 111), but the taxon is now placed in the subgenus Mesembrinus Albers, 1850 (comb. n.).

Current systematic position.

Bulimulidae , Drymaeus (Mesembrinus) conicus da Costa, 1907.
