Cercopsis (1 Viewer)

Is the name Cercopsis for a bird just the name Cereopsis Latham with a typo? It seems that the name Cercopsis (or alternatively Cercopis) is an insect. But, in most of old publications explaining the taxon Alectorides, the name Cercopsis is used, along with Glareola, Dicholophus, Palamedea, Chauna and Psophia to define this "family". Maybe the first one got it wrong and the others just reproduced the mistake?

Examples of this use here, here and here.

Does someone know where I can find Illiger's original description of this taxon?

Thank you very much Taphrospilus!

If of any help?

PS. The reason for the different entries being on either one, or two, lines (and/or colours) is a Key tech (computer) thing.
They still have the same meaning, they all lead to Cereopsis.
-

Neave ([here]) attributed "Cercopsis" to Billberg 1828, [here]; Billberg attributed it directly to Latham as if the latter had written it that way, and placed it (together with Chionis) in a 'natio'* Cereopsides, with the stem spelled correctly. This was quite clearly a mere typo there too, in any case.
The insect "Cercopsis" seems to be an incorrect subsequent spelling as well, by the way -- Cercopis Fabricius 1775 being the correct form.

*) 'Natio' was the word Billberg used for family-group taxa. (He was the first author to form family-group names correctly from many avian genus-group names; but Bock 'omitted' to check his work back in the 1990s, thus none of these names is credited to him.)

Thank you very much Björn and Laurent!

I must have missed the entry in the HBW Alive Key.
