Taxacom: Superfluous replacement names (Zoo Code)

[Laurent Raty]

Hi,

It seems obvious that Capitella fabricii Blainville must have been 
intended as a new replacement name (nomen novum; see Art. 12.2.3) for 
Lumbricus capitatus Fabricius, introduced by Blainville to avoid a 
situation of virtual tautonymy. (I.e., to avoid using a binomen that 
would combine a generic and specific name of same derivation.)

This replacement was certainly not made "without a reason"; but it was 
made for a reason that the current Code does not recognize as valid (see 
Art. 18).

Cheers, Laurent -
