Catalogue of Life has the canonical Geotrupes stercorarius twice with different authors. Once accepted and once as a synonym of Geotrupes spiniger.

In particular this is also true for infraspecific names such as Crotalus triseriatus triseriatus, see NubGeneratorIT.testColInfraspecifics().

The nub currently only allows one usage per canonical name unless they are homonyms.
How can this be improved? List those names as homonyms (read all those homonyms from CoL at HomonymInformer bootstrapping?)

Geotrupes stercorarius Erichson, 1847 Species synonym for Geotrupes spiniger Marsham, 1802 Animalia
Geotrupes stercorarius Linnaeus, 1758 Species accepted name Animalia

he combination authorship must be different to allow several usages with the same canonical name.
These two Geotrupes stercorarius name for example could well represent the same taxon as the one with just the basionym author does not specify which combination author was meant. These 2 should therefore not coexist in the backbone:

  • Geotrupes stercorarius (Linnaeus, 1758) (ACC)
  • Geotrupes stercorarius Erichson, 1847 (SYN) for Geotrupes spiniger (Marsham, 1802)
