Edit

The zoological code (http://www.nhm.ac.uk/hosted-sites/iczn/code/) allows citation of contributions authors as "A in B".

"Recommendation 51E. Citation of contributors. If a scientific name and the conditions other than publication that make it available [Arts. 10 to 20] are the responsibility not of the author of the work containing them, but of some other person(s), or of less than all of joint authors, the authorship of the name, if cited, should be stated as "B in A", or "B in A & B", or in whatever form is appropriate to facilitate information retrieval (normally the date should also be cited)."

Currently this can only be handled in the AbbrevTitleCache of the author with an extra record for this author that contains both information. Alternatively we could have an extra field for the "in" author for zoological taxon names. Or maybe even 2 such fields for combination author and original author.

Examples for this were first observed in edaphobase.
