Castor fiber Linnaeus, 1758 is therefore the type species of Castor by Linnaean tautonymy. |
Instead we should look to Speusippus' analysis of tautonymy and heteronymy and bypass eponymy altogether. |
The main difference is that the animal code allows tautonymy, while the plant code prohibits it. |
The type of Amphidesma must, by tautonymy, be regarded as A. donailla. |
