Type locality.

"Quito, Ecuador".

Type material.

NHMUK 1975244, lectotype ( Breure 1978: 31).

Additional material.

NHMUK 1975245 (1), paralectotype.

Diagnosis.

Shell relatively large, irregularly streaked with white and chestnut-brown, sculptured with incrassate growth striae and spirally incised lines, giving the shell a puckered appearance, aperture truncate-ovate, columellar margin twisted, peristome slightly expanded below.

Dimensions.

Shell height 81.5, diameter 42.0 mm.

Distribution.

Ecuador, without precise locality.

Remarks.

The material described by Pfeiffer originated possibly from southern Ecuador. The figured specimen by Strebel (1909) was based on material without locality data. This species is related to Thaumastus (Thaumastus) hartwegi (Pfeiffer in Philippi, 1846), Thaumastus (Thaumastus) flori (Jousseaume, 1897), and Thaumastus (Thaumastus) orcesi Weyrauch, 1967.
