Remarks.

Cuming’s material might have originated in the Province of Moyobamba rather than near the locality of the same name. This taxon was regarded by Richardson (1993) as a junior subjective synonym of Sultana sultana Dillwyn, 1817, possibly reflecting the opinions of Parodiz (1962: 456), who wrote "I am inclined to think that Orthalicus meobambensis Pfeiffer is a synonym", and of Pilsbry (1899: 191) stating "from the description ( …) I would think meobambensis identical with the upper Amazonian variety of Orthalicus sultana ". We agree that both species are closely related, but refrain from this conclusion until the variation of both taxa is better documented.
