Bulimulus (Lissoacme) apodemetus ; Pilsbry 1896 [1895-1896]: 187, pl. 51 fig. 1-3.

Bulimulus (Bulimulus) apodemetus ; Breure 1975b: 1145.

Type locality.

"republica Argentina; republica Boliviana"; see Breure 1973: 114.

Label.

"Monte grande, chiquitos (Bolivia)" [.178,. 181]; "Pampa ruis (laguna) Bolivia" [.179]; "Vilna (Valle grande) Bolivia" [.180]; "Sn Lorenzo Parana Rep. argentina" [.182], all in in d’Orbigny’s handwriting.

Dimensions.

"Assez variables; les plus along´s ont, de longueur, 28 millimètres sur 18 de largeur, tandis que les plus courts offerent 23 millimètres de longueur, sur 12 de largeur"; largest specimen H 28.3, shortest H 22.7, figured specimen H 23.0, D 12.6, W 6.2 [.182].

Type material.

NHMUK 1854.12.4.178-182, five lots with resp. eight, seven, seven, three and three syntypes ( d’Orbigny coll.).

Remarks.

d’Orbigny (1935) did not state on how many specimens his description was based. In d’Orbigny (1838 [1834-1847]: 280) the localities were specified as "sur les coteaux du Parna, province d’Entre-rios, près de Feliciano (...) près de San-Lorenzo, province de Santa-Fe. (...) la république de Bolivia (...) des provinces de Valle grande et de la Laguna (...); (...) des plaines de Santa-Cruz de la Sierra, (...) la province de Chiquitos"; see also Breure 1973. The shell of the largest specimen among the lots, in. 178, is broken on the ventral side. The protoconch of the type material proves to be smooth and the taxon is now being transferred from the genus Bulimulus Leach, 1814 to Bostryx Troschel, 1847 sensu Breure 1979 (but see Breure 2012b).

Current systematic position.

Bulimulidae , Bostryx apodemetus ( d’Orbigny, 1835) (comb. n.).
