[Taxacom] Species-level homonyms - between/within codes

Well Tony, Wikisp. may have the disadvantage of manual entry, but it has the 
advantage of a bit more scrutiny than automated approaches which are often 
leading to GIGO problems. For example, in your list:

Cynthia carnea 
    Cynthia carnea Fritsch (Animalia-Arthropoda-Insecta-Lepidoptera-Nymphalidae) 
.. within genus: Cynthia Fabricius, 1807 

    Cynthia carnea (Agassiz, 1850) 
(Animalia-Chordata-Ascidiacea-Stolidobranchia-Pyuridae) .. within genus: Cynthia 
Savigny, 1816 .. (Current name: Dendrodoa carnea) 

it is going to take a bit of sorting out, but it is looking quite likely that 
the lep name is bogus. You probably got it from databases which ultimately 
harvested LepIndex names. LepIndex is VERY RAW and often sketchy with details. 
There is very little data (verifiable or otherwise) given on it about Cynthia 
carnea, but what is indicated is that the name was infrasubspecific (and 
therefore unavailable) when originally proposed. MAYBE someone later validated 
it, but LepIndex provides no reason to think that, and if it is so, then the 
name dates from the subsequent publication (if there is one). If, as I suspect, 
it hasn't been validated, then there is no homonymy of any kind going on here

Dear Stephen, all,
I’ve just modified my display code so that the original genus and its authorship 
is also displayed along with each homonymous species name, which may be of 
interest to users and also with regard to wikispecies entries etc.
However I’m not sure how manual wikispecies data entry will scale to cope with 
the hundreds/thousands of disambiguation pages needed for the cases of 
within-genus homonymy, not presently included in my list; there are plenty of 
these to be found e.g. within Catalogue of Life, see for example

(I am presuming that not all of these can in fact be “provisionally accepted 
names” even though listed as such, and maybe the promised appearance of “The 
Plant List” will fix the majority of these as synonyms).
Regards – Tony
