mention it at all. When you describe a new species you must give it a
species name (which due to a historical accident also means giving it
a genus name) -- that is all. There is no requirement to say anything
at all about Subfamily, Family, Suborder and all the rest. Just say
which is the least inclusive clade that you're pretty confident that
it belongs to, and move on. Anything else is just castles in the
And this of course is exactly what we did a few years ago when
describing a sauropod that was too aberrant to refer confidently to
any of the known sauropod families. We just named the species
(Xenoposeidon proneneukos), referred it to Neosauropoda incertae
sedis, and we were done.
Hopefully one day someone will discover a more complete specimen of it
or a relative, and be able to show that it's a super-derived
titanosaur or rebbachisaur whatever. But until then, there would be
no value at all in assigning it to a "family". Even if we knew what
