Another example from entomology:

Heterotoma Bourlet, 1839 (a genus of Collembola, springtails,
now called Orchesella)

Was called Heterotoma by Bourlet, because he, mistakenly used the
differently segmented antennae for a taxonomical character...

One can find often specimens of Orchesella with two different antennae,
due to incomplete regenerated broken antennae...
