Bulimus sporadicus d’Orbigny 1837 [1834-1847]: 271, pl. 32 figs 12-15 [3 April 1837; text 23 April 1838] [partim]; Gray 1854: 15.

Bulimulus (Bulimulus) bonariensis sporadicus ; Breure 1975b: 1145 [partim]; Miquel 1991: 101, figs 39-42.

Type locality.

"provincia Corrientes (republica Argentina); provincia Chiquitensi (republica Boliviana)"; see remarks.

Label.

"Corrientes. rep. Argentina [.158]", "Chiquitos Bolivia [.159-160]", all in d’Orbigny’s handwriting.

Dimensions.

"Longit. 33 millim.; latit. 14 ad 17 mill."; figured specimen herein H 27.8, D 12.8, W 7.6.

Type material.

NHMUK 1854.12.4.160, lectotype and six paralectotypes; 1854.12.4.158, seven specimens (see remarks); 1854.12.4.159, six paralectotypes ( d’Orbigny coll.); see remarks.

Remarks.

d’Orbigny (1838 [1834-1847]: 271-272) mentioned variation observed in specimens from different localities, without assigning specific varietal names or signs. Three lots are present in the NHMUK collection, resp. seven (1854.12.4.158), six (.159) and seven specimens (.160). The largest specimen (in lot. 158) measures H 39.8, D 15.8, W 8.6, and corresponds to the ”variété la plus allongée”; this variety from northern Argentina is considered by Miquel (1991: 95, 98) as Bulimulus bonariensis bonariensis (Rafinesque, 1833). Of the two other lots-from central Bolivia-one specimen, corresponding to d’Orbigny 1837 [1834-1847]: pl. 32 figs 12-13, is here selected lectotype (design. n.) to define the taxon. Breure (1975b) listed in total 15 syntypes in the MNHN collection; Miquel (1991) only considered those of "var. B" to belong to this taxon.
