RBINS/MT2363, lectotype (design. n.); MT2364, three paralectotypes, ex Cousin (Dautzenberg coll.).

Remarks.

The original Cousin label mentions the taxon name only; the locality has been added by Dautzenberg, probably on the basis of Cousin’s paper. One specimen was found with the Cousin label stuffed inside the aperture and is here designated lectotype. The taxon is considered a junior subjective synonym of Bulimus thompsonii Pfeiffer, 1845 (syn. n.).

Current systematic position.

Orthalicidae, Kara thompsonii (Pfeiffer, 1845) (comb. n.).
