Drymaeus multispira da Costa, 1904 Figs 11C , L39vi

Drymaeus multispira da Costa 1904: 5, pl. 1 fig. 4; Breure 1979: 122 (lectotype designation).

Type locality.

"Chuco Chaca, Bolivia, 4,000 feet".

Label.

"Chuco Chaca / Bolivia 4000 ft", in da Costa’s handwriting.

Dimensions.

"Long. 20, diam. 11 mm."; figured specimen herein H 19.9, D 11.11, W 6.5.

Type material.

NHMUK 1907.11.21.31, lectotype (da Costa coll.).

Remarks.

da Costa wrote "the shells of this species", implying that he had seen more than one specimen. Breure (1979) referred to this (subadult) specimen as "HT BMNH 1907.21.31"; under Art. 74.6 ICZN Breure’s designation may be considered as a lectotype designation. The protoconch is sculptured with very indistinct spiral lines and some granules; the taxon is here transferred to Bostryx sensu Breure 1979 (comb. n.); see also Breure 2012b. It is now considered as a subjective junior synonym of Helix torallyi d’Orbigny, 1835 (syn. n.).

Current systematic position.

Bulimulidae , Bostryx torallyi ( d’Orbigny, 1835).
