Species Pecten propinquus Hupé 1854

Discussion / Comments:
Griffin & Nielsen (2008):
TYPE MATERIAL. Two syntypes in the Typothèque of the Laboratoire de Géologie under catalogue number MNHN-Gg2002/91. REMARKS. Philippi (1887, p. 203) introduced Pecten hupeanus clearly as a replacement name for Hupé’s species, as the name was preoccupied by Pecten propinquus Münster, 1833. He also stated (and figured in pl. 47, fig. 4) that he had one additional specimen that was left in the Museum by Gay. According to Philippi its preservation seems to have been very poor in comparison to Hupé’s original figured material, but Philippi was correct in identifying both species. Möricke (1895, p. 578, pl. 13, figs 2-4) described and figured material he also correctly placed under Pecten hupeanus Philippi. Herm (1969, p. 103), who never saw Hupé’s type material, included Pecten propinquus (apparently only Hupé’s types) as a synonym of Pecten vidali Philippi, 1887. On the other hand he described Pecten hupeanus from Caldera and Coquimbo, stating that the holotype of Pecten hupeanus Philippi was in the “Museo Nacional de Historia Natural” in Santiago, Chile. However, the specimen there is the one mentioned by Philippi and labeled Pecten propinquus and left behind by Gay. As Pecten hupeanus is clearly a replacement name for Pecten propinquus Hupé, the type material is the type material available to Hupé, and not Philippi’s additional specimens (ICZN 1999, Art. 72.7). In any event, Herm (1969, p. 106) compared Pecten vidali and Pecten hupeanus as closely related species, only separable by means of slight differences in the ornamentation. The shell outline and geminate ribs indicate this species belongs in Zygochlamys Ihering, 1907.
