Type locality.

[Ecuador] "reipublicae Aequatoris, montem Cotopaxi".

Label.

"Cotopaxi, Equador / Monsr Bourcier / Consul General", taxon label in Pfeiffer’s handwriting. M.C. label style IV.

Dimensions.

"Long. 34, diam. 16 mill."; figured specimen herein H 33.9, D 17.1, W 6.2.

Type material.

NHMUK 1975370, lectotype; 1975371, two paralectotypes (Cuming coll.).

Remarks.

The original paper only quotes material collected by Bourcier as a variety from Cayembe. However, if the type was in the Pfeiffer collection it must now considered to be lost ( Dance 1966). Both the locality, and measurements agree with Pfeiffer’s paper; the taxon label is from his hand, so there is no doubt that these specimens can be considered as type material. The shell height of the lectotype as quoted by Breure (1978) is in error. This species was listed as synonym under Scutalus anthisanensis (Pfeiffer, 1853) by Richardson (1995: 346); however, the shell shape of the two taxa is different, and provisionally the two taxa are kept separate awaiting further studies.

Current systematic position.

Bulimulidae , Kuschelenia (Vermiculatus) cotopaxiensis (Pfeiffer, 1853) (comb. n.).
