Dimensions: “Long. 28‒Diam. 11 [mm]”; figured specimen herein H 24.3, D 11.0, W 5.9 . Type material: MHNG-INVE-64519 , one paralectotype (ex Morelet, Moricand coll.). Remarks: Morelet did not state on how many specimens his description was based. The lectotype is in the NHMUK ( Breure & Ablett, 2014 ). This sinistral species may prove to be identical with one of the other, dextral, Drymaeus species occurring in its distribution range as enantiomorphy within this group may be more commonly found than currently thought (Breure, unpublished data). The current systematic position follows Thompson (2011) . Current systematic position: Bulimulidae , Drymaeus ( Mesembrinus ) tropicalis ( Morelet, 1849 ) .
