Gyrinus orientalis Régimbart, 1883

Gyrinus orientalis Régimbart, 1883: 167 is a junior primary homonym of Gyrinus orientalis Modeer, 1780: 160 (currently in Dineutus ), and thus Régimbart’s name is permanently invalid. At present both taxa are treated as different valid species. Article 23.9.5 of the ICZN (1999) cannot be applied because Modeer’s name was transferred to the genus Dineutus only by OCHS (1926a: 73) and not before 1900. There is no name available to replace G. orientalis Régimbart. OCHS (1929: 2) published a ‘female form’ politus of G. orientalis Régimbart , but this is an infrasubspecific entity, and thus not an available name according to Article 45.6.4 ( ICZN 1999).

This is why we hereby replace the permanently invalid name Gyrinus orientalis Régimbart, 1883 by a new replacement name, Gyrinus mauricei nom. nov. The name is a substantive in the singular genitive formed from the forename of Maurice Régimbart and in honour of that great entomologist.
