Harpalus siculus Dejean, 1829: 316 .

The lectotype is a male bearing labels “a male symbol, “ siculus m. in Sicilia ”, “Schüppel”, “ HOLOTYPE ”, “vidit Z. Mylnář det 1974”, “ LECTOTYPE ” and “ Holotype of Harpalus siculus Dejean, 1829, J. Serrano vidit.” .

The card stating LECTOTYPE was likely placed by Mylnář, but this is a mislabelling as the specimen is the holotype (see below). Dejean (1829) briefly stated the origin of the specimen: Il se trouve en Sicile. From the original description it is inferred that he only could study a single specimen sent by M. Schüppel. Thus, this specimen becomes the holotype of the species by monotypy. Although Mylnář did not formally publish the recognition of this specimen as the holotype, it is clear from the label that he recognized the type condition of the specimen he saw. Keys to the species are available in Fuente (1927) and Antoine (1959).

To date the species is known from Italy, Spain and the Maghreb (Kataev & Wrase, 2017c).
