Bulimulus laxostylus Rolle, 1904 Figs 74E-G , L33v

Bulimulus laxostylus Rolle 1904: 37; Breure 1979: 110.

Type locality.

"Huancabamba in Peru".

Label.

"Huancabamba / Peru / Andes 6-10.000 ft.", taxon label in Rolle’s handwriting.

Dimensions.

"Alt. 40, diam. 16,5 mm"; figured specimen herein H 39.9, D 15.4, W 7.1.

Type material.

NHMUK 1922.2.24.32, lectotype (ex Rolle).

Remarks.

Rolle did not mention on how many specimens his description was based; the label reads "largest is type", suggesting that more than one specimen might have been seen. The record of the holotype in Breure (1979: 110) has therefore to be interpreted as lectotype designation. The taxon is here figured for the first time. See also remarks on locality and publication date under Bulimulus (Drymaeus) abruptus Rolle, 1904.

Current systematic position.

Bulimulidae , Drymaeus (Drymaeus) laxostylus (Rolle, 1904).
