Diagnosis.

Shell elongate-ovate, rather solid, broadly perforate, whitish with tawny blotches, sculptured with incrassate growth striae, suture slightly ascending behind the lip, aperture squarish oblique-ovate, with four teeth (small palatal lamella, indistinct basal lamella, concave columellar lamella entering the aperture, rectangular parietal lamella), peristome thickened, well expanded, narrowly reflexed.

Dimensions.

Shell height 34.8, diameter 11.0 mm.

Distribution.

Bolivia, Dept. Santa Cruz, Prov. Chiquitos ( d’Orbigny 1838 [1834-1847]). Paraguay. Argentina ( Cuezzo et al. 2013). Brazil ( Simone 2006).

Ecoregion.

Chiquitano dry forests [NT0212].

Remarks.

Breure (2013: 14) discussed the need for an in-depth study of the variation of this wide-ranging species; preferably with anatomical and molecular research. The Bolivian record based on d’Orbigny (1838) “frontières nord de la province de Chiquitos" needs further confirmation. The Bolivian material which is found as Spixia striata in museum collections may need re-identification in the light of the recent split of the two varieties of d’Orbigny.
