Galton has recently applied for the designation of a neotype for the Late Triassic sauropodomorph dinosaur Plateosaurus engelhardti Meyer, 1837 under Article 75.5 of the Code. Whereas I support Galton’s application to have Meyer (1837) rather than Meyer (1839) formally established as the authority for Plateosaurus engelhardti, there are issues that lead me to urge the Commission to reject his proposed designation of a neotype.
The purpose of this comment is to request the Commission to issue a ruling on Case 1721, which has been in limbo since the original application made 45 years ago (Nielsen & Klausewitz, 1968) and completed by an additional request 41 years ago (Woodland, 1972). The case and the subsequent comments concern three generic names of fishes well known in the literature. They are in frequent use by ecologists; incorporated in legal instruments on conservation and international trade; used in the aquarium-fish trade; and in aquaculture.
The application presented by Gaimari, Hauser & Fricke tries to modify a correctly formed name (PHYCINAE Lyneborg, 1976) to conserve an incorrectly formed name (PHYCINAE Swainson, 1838), creating complications instead of solving them with the extant rules of the Code. This application overlooks the fact that the Latinized Greek name for the fish genus Phycis makes a genitive Phycidis, and consequently its stem is Phycid-, as the Greek noun ???ί? (a fish that hides among seaweed) makes a genitive ???ί???.
The abovementioned case submitted by Bauernfeind and Haybach is of critical importance for taxonomists and ecologists dealing with Ephemeroptera throughout the world.
I strongly support the proposed conservation of usage by designation of a neotype for Ephemera venosa (currently Ecdyonurus venosus) for the following reasons:
The commonly used name Arion fasciatus (Nilsson, 1823), originally Limax fasciatus, is a junior primary homonym of the dubious and hardly used name Limax fasciatus Razoumowsky, 1789. Falkner et al. (2002, p. 141) declared Limax fasciatus Razoumowsky, 1789 a nomen oblitum in accordance with Article 23.9.2 of the Code with the aim of preserving the current usage of the name Arion fasciatus (Nilsson, 1823). Von Proschwitz & Falkner demonstrated that this action had been taken in error, because the conditions of Article 23.9.2 of the Code were not met.
Nordsieck (BZN 70: 43–45) argues again that Linnaeus’s Turbo bidens was based on the species better known as Papillifera papillaris (Müller, 1774). Giusti & Manganelli (2005) and Kadolsky (2009; BZN 69: 213–218) concluded that Linnaeus so named the species now known as Cochlodina laminata (Montagu, 1803), and gave a bibliographic reference to a different Cochlodina species of very similar external appearance, C. incisa (Küster, 1876).
