Given the significance of such crests in specific recognition, I would
generally not give such differences more than specific significance. Such
crests will tend to differ substantially, and more or less randomly,
between closely related species.

I am not sure would give this much weight. Unless a rather different
ontogeny is indicated, I would tend to treat this as just a
species-specific variant of the same structure.
In short, unless more differences are described, I will probably treat
_Rinchenia_ as a junior synonym of _Oviraptor_ when it *is* published.
