We're not really disagreeing. Yes, IOSPE recognizes 3 genera for 3 species. I just think it is likely that they never incorporated the merge when it was new in 2001 and have never revisited it, rather than deciding to split them again more recently as you seem to imply. I don't think it has any bearing on what is generally accepted now. IOSPE does a fantastic job providing a huge amount of relatively up-to-date information on publications, but I don't think passing judgement on recent taxonomic changes is their strength or their real mission.
