What is correct according to the code?

  • Oreotrochilus adela (d'Orbigny, 1838)
  • Oreotrochilus estella (d'Orbigny, 1838)

...as in IOC World bird list or...

  • Oreotrochilus estella (d'Orbigny & Lafresnaye, 1838)
  • Oreotrochilus adela (d'Orbigny & Lafresnaye, 1839)

...as in Avibase. The OD is to find here. From the title of the article here...

Synopsis Avium ab Alcide d’Orbigny, in ejus per Americam meridionalem itinere, collectarum et ab ipso viatore necnon a de Lafresnaye in ordine redactarum

...both could be the authors. The decriptions of course have only d'Orbigny.

As Oreotrochilus adela has a publishing date of 1839 in Avibase I tend to trust IOC World bird list.
 
Synopsis Avium ab Alcide d’Orbigny, in ejus per Americam meridionalem itinere, collectarum et ab ipso viatore necnon a de Lafresnaye in ordine redactarum
This means "Synopsis of the birds collected by Alcide d'Orbigny, in his voyage through southern America, and written in order by this traveller as well as de Lafresnaye". Based on this, I would regard both d'Orbigny and Lafresnaye as the authors of the work.

However, if a name in this work is explicitly attributed to d'Orbigny alone, then Art. 50.1 says:
If a work is by more than one person but it is clear from the contents that only one of these is responsible for the name or act, then that person is the author
...and d'Orbigny alone is the author of this name.
 
Thank you Laurent. In Dickinson & Lebosse 2018 and as to T. Estella footnote 230 states "We consider that this credit to d’Orbigny alone implies that the authors believed the plate would appear first." Not sure what that means.
