Type locality: “provincia Chiquitensi (republica Boliviana)”.

Label: “Chiquito[s]”, in Moricand’s handwriting.

Dimensions: “Longit. 41 millim., latit. 19 millim.”; figured specimen herein H 43.9, D 19.5, W 7.3.

Type material: MHNG-INVE-63469, four paralectotypes (ex d’Orbigny, Moricand coll.).

Remarks: d’Orbigny did not state on how many specimens his description was based; additional type specimens are present in NHMUK and MNHN collections; the lectotype is housed in the latter collection. The current systematic position follows the synonymisation of this taxon with Helix abyssorum d’Orbigny, 1835 , by Miquel (1989b: 77); see also Breure & Ablett (2014).

Current systematic position: Bulimulidae , Drymaeus (Drymaeus) abyssorum (d’Orbigny, 1835) .
