A. lacustris (Luetken, 1875)

Tetragonopterus lacusris Luetken, 1875

Tetragonopterus jacuhiensis Cope, 1894 info Astyanax bimaculatus paraguayensis Eigenmann, 1921

Astyanax bimaculatus asuncionensis Géry, 1972 info Astyanax altiparanae Garutti & Britski, 2000

type locality bimaculatus paraguayensis : Paraguay remarks Bertoni (1914) listed the subspecies A. bimaculatus paraguayensis 7 years before Eigenmann (1921)

presented the same as “subsp. nov.”. Therefore the taxon exists twice with different authorship, but the one of Bertoni must be treated as a nomen nudum as it was published as a mere listing without any further information than the name.

A. bimaculatus asuncionensis was proposed by

Gèry as a replacement name for Eigenmann’s A.

bimaculatus paraguayensis, preoccupied in

Astyanax by A. paraguayensis ( Fowler, 1918) .
