''Hyalopecten'' is a genus of marine bivalve mollusks. The placement of the genus ''Hyalopecten'' is currently uncertain. Habe〔Habe, T. (1977): ''Systematics of Mollusca in Japan. Bivalvia and Scaphopoda''. 372 pp., Zukan no Hokuryukan, Tokio.〕 included ''Hyalopecten'' within the subfamily Camptonectinae. However, ''Hyalopecten'' lacks antimarginal microsculpture, which is a key characteristic of Camptonectinae.〔Waller, T. R. & Marincovich, L. jr. (1992): ''New species of'' Camptochlamys ''and'' Chlamys ''(Mollusca: Bivalvia: Pectinidae), from near the Cretaceous/Tertiary Boundary at Ocean Point, North Slope, Alaska''. Journal of Paleontology 66 (2): 215-227〕 Some authors consider ''Ciclopecten'' Seguenza, 1877 to be a senior synonym, however ''Ciclopecten'' has antimarginal microsculpture. ==Species and their Distribution== *''Hyalopecten frigidus'' (Jensen, 1904) - North Atlantic and Arctic Ocean *''Hyalopecten hadalis'' (Knudsen, 1970) - Kermadec Trench *''Hyalopecten mireilleae'' Dijkstra, 1995 - Eastern New Caledonia to the New Hebrides *''Hyalopecten neoceanicus'' (Dall, 1908) - Eastern Pacific coast from Oregon to northern Peru, including the Galapagos Islands *''Hyalopecten profundicola'' (Okutani, 1962) - Aogashima Island, Japan *''Hyalopecten pudicus'' (E.
