Re: Magnapaulia, "new" lambeosaurine from Baja California, Mexico
New paper in PLoS ONE, creating a new genus (Magnapaulia) for
"Lambeosaurus" laticaudus. Since the gender of the new generic name
is feminine, the correct Neo-Latin combination technically should be
Magnapaulia laticauda. The specific "laticaudus" was originally
formed from the Latin latus "wide" + noun cauda "tail" and made
masculine to match the gender of Lambeosaurus....
...which was wrong in the first place. You can't change the gender of a
noun, and that's what "tail" is. The ICZN even spells out that species
names which are "nouns in apposition" don't need to agree, and must not
be made to agree, with the names of their genera.
Word to the wise: if you want "-tail_ed_" instead of "-tail" in a name
you create, use "-caud_at_us/-a/-um". I forgot what it was, but a recent
paper erected a "-caudatus" name and pretended to derive it directly
from "cauda"; probably also declared it to be Greek while it's in fact
