The identity of Pecten solidulus Reeve, 1853, a species from an unknown locality, has always been subject to debate. As type species of Argopecten Monterosato, 1889, by subsequent designation by Monterosato himself (1899: 193), the identity of the genus is connected with the identity of the species. Initially Monterosato (1889: 20) relegated his Pecten commutatus, which he described in 1875, to the synonymy of P. solidulus. This synonymy was regarded as erroneous by Dautzenberg & Fischer (1906: 59). Grau (1959: 93) has regarded P. commutatus as type species for the genus Argopecten, because in his opinion P. solidulus was unidentifiable. Keen (1960: 101) has pointed out that he did so incorrectly.
