«During comparative studies of Recent Pectinidae taxa, it was noted that several actually used species names are preoccupied and in need of rectification. In this series new names of taxa are proposed in accordance with the third edition of the International Code of Zoological Nomenclature (ICZN, 1985), and their current classification is treated.
This first part deals with the epithets aurantia(us) and aurantiaca (us). One new species name (Anguipecten picturatus nom. nov. for Pecten aurantiacus Adams & Reeve, 1850, nec Roding, 1798) is introduced and a lectotype is designated for Ostrea senatoria Gmelin, 1791. (...) Anguipecten picturatus nom. nov. According to modern views (Dijkstra, 1984, 1991; Waller, 1986), this taxon should be assigned to the genus Anguipecten Dall, Bartsch & Rehder, 1938, which is placed in the tribe Decatopectinini by Waller (1986). Etymology. ─ Lat., picturatus = gay-coloured. Distribution. ─ Western and southwestern Pacific.» HENK H. DIJKSTRA, 1995

«Description. — Shell solid, up to c. 50 mm high, most specimens smaller, somewhat triangularly elongate, posterior margin longer than anterior, left valve almost flat, right valve weakly convex, slightly inequivalve and inequilateral, auricles short and almost equal in size, umbonal angle 80˚-85˚; cream, maculated with dots and streaks, right valve paler and more uniform in colour than left. Both valves sculptured with 12-14 primary radial costae and secondary radial riblets, riblets somewhat more prominent on costae than in interstices. Microsculpture of closely spaced commarginal lamellae. Auricles weakly sculptured with radial riblets near disc flank, sculpture of anterior auricle of right valve most prominent. Hinge line straight, somewhat raised on right valve. Inner surface plicated, internal rib carinae weak, carinate riblets present near margin. Adductor scar insertion prominent. Resilifer triangular, oblong, resilial teeth weak, intermediate teeth strongly developed. Byssal notch shallow, byssal fasciole absent; functional ctenolium weak, with 3 teeth.
Distribution. — Indo-West Pacific, from southern Japan to northern Australia, westwards to the east coast of Africa and eastwards to Fiji. Okinawa (Japan) southwards to tropical West Pacific: 10-50 m (Hayami, 2000: 903), Taiwan, South China Sea: intertidal zone to 25 m (Bernard, Cai & Morton, 1993: 50), Philippines: 25 m (Raines, 2010: 596), Indonesia: 59-275 m, dead (Dijkstra, 1991: 41), Zululand, South Africa: 100 m, dead (Dijkstra & Kilburn, 2001: 273). Present specimens from the Philippines alive at 80-90 m. The bathymetric range of live-taken specimens is from 10-120 m. Living under coral slabs or boulders or amongst coral rubble on soft sediment (sandy bottoms). Remarks. — The present specimens from the Philippines are morphologically identical to the type specimen from the South China Sea.» DIJKSTRA, H. H. 2013.
