Alan,

I think you're conflating taxonomy and nomenclature.  The nomenclatural
rules prohibit use of the name Anapagurus marginatus for two different
animals, REGARDLESS of their taxonomic positions.  It sounds as though
Garcia-Gomez could have tidied up the nomenclature while adjusting the
taxonomy.
