† Gyrinus dubius Giebel [† Paragyrinus ] and Gyrinus dubius Wallis

History of classification. Gංൾൻൾඅ (1856) published Gyrinus dubius by indication to fig. 6 of plate VII (an unnamed Coleoptera ) in Bඋඈൽංൾ (1845). HൺඇൽඅංඋඌർIJ (1906: 448) [not in 1908] introduced the generic name † Paragyrinus [not OർIJඌ 1924: 231] for Giebel’s taxon, accompanied by the remark that it does not belong to Gyrinidae . Nൾඅ (1989: 328) listed it with doubtful assignment to family Gyrinidae . This fact has, however, no impact on the homonymy given below.

Homonymy. Gyrinus dubius Wallis, 1926: 93 is a junior primary homonym of the fossil † Gyrinus dubius Giebel, 1856: 56 (currently in † Paragyrinus Handlirsch, 1906 ), and thus Wallis’ name is permanently invalid.

No junior synonym of Gyrinus dubius Wallis is known which might substitute Wallis’ name according to Article 60 of the ICZN. This is why we hereby replace the junior primary homonym of Gyrinus dubius Wallis, 1926 with Gyrinus suspectus nom. nov. The specific name is a Latin adjective in the nominative singular and is chosen because its meaning is more or less the same as ‘dubius’ [= doubtful]. A potential homonymy with the name Gyrinus dubius Motschulsky, 1853 can be disregarded because this name is a nomen nudum and thus unavailable.
