Recommendations concerning the presentation of synonymic and related lists in zootaxonomy: the example of the family Cryptobranchidae Fitzinger, 1826 (Amphibia, Urodela)

Abstract

Synonymic and related (logonymic) lists play important roles in taxonomy: they give the valid and correct nomina of the taxa of a zoological group, they allow to know whether nomina are available for naming newly recognised taxa, and they provide a condensed history of the taxonomy of the group. To be really useful, such lists should be complete and accurate. This is not always the case, in particular in many taxonomic and nomenclatural online databases, which should be used with great caution. Recommendations are offered concerning the presentation of such lists in order to make them more useful and reliable. They are illustrated by the family-series and genus-series logonymic lists of the amphibian family Cryptobranchidae.
