Although there's never been a formal system for it, I believe I usually consider more specific taxon descriptions to be more important, e.g. Oozlebachridae, being based on the positioning of certain parts, is more specific than Carnitoria, which is based only on the largest mouthparts, hence carnivorous cells with front-facing spikes go in the former taxon.
