Taxonomy and nomenclature of the genus Complicachlamys Iredale, 1939, and its species (Bivalvia, Pectinidae)
Basteria , Volume 53 - Issue 4/6 p. 111- 116
The genus Complicachlamys Iredale, 1939, was created for four species, viz. Pecten fulvicostatus Adams & Reeve, 1848, P. luculenta Reeve, 1853 (with P. dringi Reeve, 1853, as junior synonym), P. crouchi E. A. Smith, 1892, and Complicachlamys wardiana Iredale, 1939. The latter was designated as type species. As the identity of P. fulvicostatus, P. luculenta and P. dringi has been subject to debate in the past, a critical examination of the remnant type material was carried out. The type material studied exists of holotypes of P. fulvicostatus, P. crouchi, C. wardiana and two samples, of three syntypes each, of P. luculenta and P. dringi. The two samples of syntypes comprise more than one species, thus lectotypes are designated in order to stabilize the names. The figured syntypes are selected as lectotypes, and as a consequence both P. luculenta and P. dringi become junior synonyms of P. fulvicostatus. P. fulvicostatus can be assigned to the genus Semipallium Jousseaume, 1928. The recently described Semipallium barnetti Dijkstra, 1989, is relegated to the synonymy of Semipallium fulvicostatum. The holotype of P. crouchi also belongs to Semipallium. One of the paralectotypes of P. luculenta probably belongs to Chlamys lemniscata (Reeve, 1853). The two paralectotypes of P. dringi belong to the type species of Complicachlamys: C. wardiana. The genus Complicachlamys is rejected and is relegated to the synonymy of the genus Chlamys Röding, 1798.
