Drymaeus obliquistriatus da Costa, 1901 Figs 8E , L42vi

Drymaeus obliquistriatus da Costa 1901: 238, pl. 24 fig. 2; Breure 1979: 136.

Type locality.

"San Pablo, Peru".

Label.

"San Pablo, Peru", in da Costa’s handwriting.

Dimensions.

"Long. 30, diam. 12 mm."; figured specimen herein H 28.9, D 12.7, W 7.8.

Type material.

NHMUK 1907.11.21.41, lectotype (da Costa coll.).

Remarks.

The type locality remains unspecified, as there are several localities named "San Pablo" throughout Peru. Da Costa did not mention on how many specimens his description was based. The reference of Breure (1979) to "HT 1907.11.21.41" has to be interpreted as a lectotype designation under Art. 74.6 ICZN. The protoconch of the specimen is smooth, and the shape is like those found in Bostryx sensu Breure 1979; thefore, the taxon is now transferred to this genus (comb. n.). There is a mismatch in the taxon name between the label and the published name.

Current systematic position.

Bulimulidae , Bostryx obliquistriatus (da Costa, 1901) (comb. n.).
