Gyrinus striatus Olivier, 1795

Gyrinus striatus Olivier, 1795: 11 was missing in the ‘ PalCat ’. It is a junior primary homonym of G. striatus Fabricius, 1792: 203 (currently in Aulonogyrus ), and thus it is permanently invalid.

It is quite clear that Gyrinus striatus Olivier denotes one of the two Aulonogyrus species known from Europe: A. concinnus (Klug, 1834) or A. striatus ( Fabricius, 1792) – both have been recorded from Spain which is the type locality of Olivier’s taxon. However, the two species are externally very similar and the description of this taxon does not allow a safe attribution to one of the two species. OLIVIER (1795) described his taxon on the basis of material from the ‘Cabinet de M. Gigot d’Orcy’. According to HORN et al. (1990: 138) Gigot’s collection should be preserved in the Muséum d’Histoire Naturelle, Genève; however, no syntypes of this taxon were found in this museum. Since the name is a junior primary homonym and thus permanently invalid, we do not consider it necessary to designate a neotype and clarify the identity of the taxon, but instead leave Gyrinus striatus Olivier as nomen dubium.
