«P. Testa crassa, inflata, rubra, striis longitudinaliter, subsquamoso-scabris ornata; radiis 8, aut 9, crassis, elevatis, rotundatis, nodosis.
Dimensions. Longueur: 34 millimètres. Largeur: 33 millimètres. Épaiseur: 17 millimètres. Coquille. Épaisse, renflée, inéquilatérale; les stries qui rayonnent du sommet aux bords sont couvertes de petites lames imbriquées, peu élevées, formant huit ou neuf grosses côtes arrondies, sailantes, sur lesquelles sont quelques nodosités par intervalles; oirelles très-inégales. Couleur. D'un beau rouge de corail, avec des interruptions jaunâtres près des tubercules; l'intérieur est rouge ou violacé. Cette espèce ressemble beaucoup au Pecten nodosus, Linn. (Pecten corallinus Chemnitz), qu'on rencontre aux Antilles.; mais il est bien plus bombé, plus irrégulier dans sa forme; ses stries sontt moins élevées; ses nodosités moins marquées; ses oreilles moins longues, et tout, dans la comparaison immédiate, annonce deux espèces voisines, mais très-distinctes. Nous avons obtenu cette coquille des pêcheurs de Santa-Cruz de Ténériffe; c'est aussi de ce lieu que MM. Webb et Berthelot l'ont rapportée.» ALCIDE D'ORBIGNY, 1839 |
«Three extant lineages emerge from the Tertiary Caribbean Nodipecten Complex (Fig. 3): N. fragosus (Conrad, 1849) (Node 9), N. subnodosus (Node 10), and N. arthriticus (Node 11), the last giving rise to the Galápagos species, N. magnificus (Node 12). Another extant species, N. corallinoides (Orbigny, 1839) of the eastern Atlantic (Azores, Canary Islands, and Cape Vert) is probably a relatively recent derivative of N. nodosus (J. T. Smith, 1991a, p. 91) and is not shown in the phylogeny.»

«Distribution. — Subtropical to tropical eastern Atlantic from the Azores southwards to the Cape Verde Islands. Living littorally to sublittoral depths amongst coral rubble on sandy bottoms. Depth range of present material 0-480 m, living at 10-90 m.
Description. — Shell up to c. 50 mm in height, usually smaller, solid, orbicular, usually commarginally undulated, slightly equivalve and equilateral. Right valve somewhat more convex than left one. Auricles very unequal in size; umbonal angle c. 95°. Left valve ornamented with 8-9 primary radial, nodose lirae. The nodose sculpture is usually very strongly developed, rarely weak or even lacking. Secondary sculpture consists of delicate, closely spaced, radial riblets throughout ontogeny and intercostal commarginal microsculpture. Anterior auricle with 6-8 radial riblets and prominent intercostal commarginal lamellae; posterior with 2-3 radial riblets near disc and 2 radial, heavily nodose ribs near dorsal margin. Right valve similarly sculptured as left valve, although with 7-8 broader primary lirae. Anterior auricle with 5-6 radial riblets. Prominent squamose sculpture on dorsal margin. Posteror auricle with 2 radial riblets near disc and 2 heavily nodose ribs near dorsal margin. Hinge line straight. Byssal notch moderately deep, byssal fasciole rather broad. Active ctenolium with 4-6 teeth. Colour left valve usually deep reddish or creamy, stained and dotted, right valve paler. Remarks. — Reeve (1852: species 26) supplied the present species with a wrong locality 'Zanzibar', subsequently followed by other authors. The Indo-West Pacific species is Bractechlamrys nodulifera (G.B. Sowerby 2nd,, 1842) and mainly differs from B. corallinoides in having a more closely spaced commarginal microsculpture, less prominent sculptured auricles and a different colour pattern. Nordsieck (1969: 54) and Rombouts (1991: 45) placed the present species in Lyropecten.» DIJKSTRA, H. H. & J. GOUD. 2002.
