I didn't find the OD of Myothera ferruginea Temminck
Are you something about Eriodora ?The Biodiversity Heritage Library works collaboratively to make biodiversity literature openly available to the world as part of a global biodiversity community.www.biodiversitylibrary.org
I typed Eriodora in the BHL search field and noticed incongruities, sometimes used as a synonym of Formicivora while squamata was placed in another genus (Ellipura). So, I don't know, I have a doubt on his type
Yes, I read that, but it has a different type species and it exists apart from Garrulax ...and 'probably a deliberate mispelling' certainly wouldn't hold up in court!
'Garrulaxis' is a subsequent spelling of Garrulax. Indeed, "probably deliberate" would not hold up in court. This name does not meet the Code requirements to be treated as a demonstrably deliberate emendation (Lafresnaye attributed it to Lesson and treated it as if Lesson had used this spelling). Hence is is to be treated as an error and is wholly unavailable.
Even if it could be interpreted as a deliberate emendation, an emendation is always an objective synonym of the original name, hence Garrulaxis, being junior to Garrulax, would be permanently invalid. (Beware that the type fixation of Garrulax itself is extremely muddy. The earliest designated type, belangeri, has more recently been regarded as nude in the OD, which resulted in another type, rufifrons, being designated. If you found two different types indicated for these two names, it is likely that these corresponded to two different treatments of Garrulax. Not to two independent treatments of Garrulax and 'Garrulaxis'.)
