Type material.

NHMUK 1975582, three possible syntypes (Cuming coll.).

Remarks.

Reeve described this taxon from "Mus. Benson", but did not state on how many specimens his description was based. According to Tillier (1980: 73), the figured specimen is in the collection of the Museum of Zoology, University of Cambridge. The material found is therefore considered as possible syntypes. The specimen figured by Pfeiffer 1853 (in Küster and Pfeiffer 1840-1865: pl. 21 fig. 1) was smaller than Reeve’s figure, but also originated from Benson’s collection.

Current systematic position.

Orthalicidae , Orthalicus bensoni (Reeve, 1849).
