Name
Spixia minor (d’Orbigny, 1837) – Wikispecies link – Pensoft Profile
- Helix spixii var. minor d’Orbigny 1835[1]: 21. Nomen nudum.
- Pupa spixii var. β minor
d’Orbigny 1837 [1834–1847]: pl. 41bis fig. 11; d’Orbigny 1838 [1834–1847]: 320; Breure and Ablett 2012[2]: 26, figs 21A–F, 21i.
- Spixia minor; Cuezzo et al. 2013[3]: 178 (references, synonymy).
Type locality
[Bolivia] “province de Chiquitos, entre Santo-Corazon et San-Juan”; see Breure 1973[4]: 123.
Type material
NHMUK 1854.12.4.231, lectotype (Breure and Ablett 2012[2]), and NHMUK 1854.12.4.231 (7), paralectotypes.
Diagnosis
Shell slender and elongate, rather thin, broadly perforate, grayish-tawny coloured, sculptured with growth striae and a faint indication of spiral lines, suture abruptly ascending behind the lip, aperture oblique-ovate, with five teeth (small suprapalatal lamella, large palatal lamella, small basal lamella, prominent columellar lamella entering the aperture, large but relatively thin parietal lamella), peristome thickened, expanded.
Dimensions
Shell height 29.2, diameter 7.46 mm.
Distribution
Bolivia, Dept. Santa Cruz, between San Juan de Chiquitos and Ruinas de Santo Corazón.
Ecoregion
Dry Chaco [NT0210].
Remarks
Breure and Ablett (2012)[2] clarified the confusion about d’Orbigny’s varietal names for Pupa spixii by selecting lectotypes for each variety and giving minor specific status; the expert opinion of Cuezzo et al. (2013)[3] is here adopted for the current systematic position.
