«Evolution.— Smith (1991b: 94) claimed that "Nodipecten nodosus evolved directly from N. collierensis in the late Miocene or early Pliocene." The basis for this claim are specimens identified as N. collierensis from the late Miocene and early Pliocene of Venezuela (Smith, 1991b: pl. 8, fig. 6, pl. 9, figs 3-4, pl. 10, fig. 6). These specimens differ from typical N. collierensis from the Tamiami Formation of Collier County, Florida, in having slightly more rounded, less distinctly paired ribs on the right valve and stronger somewhat broader minor ribs in the central sector of the left valve. In this sense, these specimens are closer to N. nodosus than is typical N. collierensis, and the Venezuelan specimens might indeed represent the beginning of the N. nodosus lineage as well as the beginning of a separate group that includes more typical N. collierensis of the southeastern United States, which evolved in the Gulf of Mexico and Florida, giving rise to extant N. fragosus.»

«Type locality
“Habitat in O. Africano & Indico”. These localities suggest, that Linnaeus is here referring to Pecten corallinoides d’Orbigny, 1839 from the Canary Islands and the Indian Ocean, which is related to the present species. However, material of P. corallinoides is not present in the UUZM or the LSL collections. Smith (1991: 93) mentioned the erroneous localities of Linnaeus (1758, 1767), and compared material (UCMP 37389, 37390) from Margarita Island, Venezuela with the selected lectotype; they were similar. The type locality is restricted herein to Margarita Island, Venezuela.
UUZM (isolated by Odhner):
A specimen with two handwritten Thunberg labels ‘‘Mus.Gust.Ad.’’ and ‘‘nodosa.’’. Inside of right valve marked in pencil ‘‘nodosa’’. This specimen is designated as the lectotype (Fig. 7E) by J.T. Smith (1991: 93) (see also Wallin, 1993: 87, Ostrea nodosa # 494). LSL (isolated by Hanley): Hanley (1855: 106) isolated two left valves, according to Dance’s accompanying printed label of which the smallest is marked ‘‘nodosa’’ in pencil on the inside. According to a label of Morris’ (1987) this mark could have been made by Hanley. However Hanley (1855: 106) mentioned only one specimen. Both specimens are typical for O. nodosa. In the Gualtieri collection of the MSNP two specimens (rv) were traced, which are similar to Linnaeus’ reference (Gualtieri, 1742: pl. 99, figs C, D). Other material UUZM (in general collection): A box with a specimen and a printed Swartz label, no accompanying Thunberg labels [ = Pecten mirificus Reeve, 1853, det. Dijkstra]. This specimen does not correspond to the type material, nor to Linnaeus’ descriptions (1758, 1764, 1767). LSL (not isolated): One left valve of Pecten corallinoides d’Orbigny. This specimen was not isolated by Hanley. It may have belonged to Linnaeus, judging by his cited localities. Small specimens of O. nodosa may be easily confused with P. corallinoides, when localities are unknown. Remarks Linnaeus (1758: 697) first referred to Buonanni (1684), figure 18, which is a Spondylus species. This reference is omitted in Linnaeus’ publications of 1764 and 1766. The second reference is to Rumphius (1705), plate 48, figure 8 (a right valve), which is similar to the type material. However, he overlooked figure 7 (a left valve), which is also similar. The third reference is to Gualtieri (1742), plate 99, figures C and D. Both figures correspond very well with the type material. The fourth reference is to Argenville (1742), plate 27, figure F. The plate number is incorrect and should be 24; figure F also resembles the type material. Current taxonomic position Ostrea nodosa Linnaeus, 1758 is the type species of Nodipecten Dall, 1898 by original designation. Hertlein (1969: N360) treated Nodipecten as a subgenus of Chlamys Röding, 1798, whereas Abbott (1974: 449) mentioned it as a subgenus of Lyropecten Conrad, 1862. Recently Smith (1991: 86) treated Nodipecten as an extant genus. The current taxonomic combination for the present species is Nodipecten nodosus (Linnaeus, 1758). Distribution N. nodosus is widely distributed in the Caribbean region from eastern Panama through the southern region of the Greater Antilles to Brazil and tropical western Africa, living in the littoral zone between coral on sandy bottoms.» DIJKSTRA, H.
