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

Label: “Chiquitos”, in Moricand’s handwriting.

Dimensions: “Longit 22 1/2 mil.; latit. a 15 ad 16 millim.”; figured specimen herein H 26.8, D 13.0, W 6.0.

Type material: MHNG-INVE-63506 , five paralectotypes (ex d’Orbigny, Moricand coll.).

Remarks: In d’Orbigny (1837 [1834-1847]) the type locality is specified for two varieties, var. major and var. minor . Var. major was found especially at “la porte de Tasajos et du bourg de Pampa grande”. Var. minor occurs in the forests bordering the “ Rio grande ”, the forests bordering “Rio de Tacabaca, entre San-Juan et Santo-Corazon de Chiquitos et aux environs de cette première Mission [San Juan]”. See also Breure (1973). The lot in MHNG belongs to the latter mentioned. All material belongs to the same species, contrasting the findings of Breure (1975) for the material in the MNHN; additional specimens are in the NHMUK ( Breure & Ablett, 2014).

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