Type locality.

"provinvia Corrientes (republica Argentina)".

Label.

"corrientes Rep. argentina", in d’Orbigny’s handwriting.

Dimensions.

"Longit. 32 millim.; latit. 7 millim."; figured specimen herein H 31.6, D 14.1, W 6.4.

Type material.

NHMUK 1854.12.4.161, lectotype and five paralectotypes ( d’Orbigny coll.).

Remarks.

The type locality has been specified in d’Orbigny 1838 [1834-1847]: 270 as "la rive sud du Rio de Santa-Lucia, dans les environs de San-Roque"; see Breure 1973: 120, fig. 8. According to Miquel (1989b: 76) this taxon does not occur in Argentina, but in Brasil. The diameter as given by d’Orbigny (1835) seems to be erroneous, also seen the H/D ration in his figure ( d’Orbigny 1837 [1834-1847]: pl. 31 figs 11-12); the publication date of this plate is not given in the collation of Coan et al. (2013a), but is herein assumed to be 1837. The specimen corresponding to this figure is selected lectotype (design.n.). The shell height given by Simone (2006) is erroneous.

Current systematic position.

Bulimulidae , Drymaeus (Mesembrinus) oreades ( d’Orbigny, 1835).
