[Taxacom] Small mystery - the name Byrrhininus Pic

Thanks Francisco - if that is the only occasion when Pic erected this genus
name, then the second entry (which I presently have ex J. Hallan's Catalog
in 2012) for "Byrrhus Linnaeus, 1767 subgenus Byrrhininus" [Family:
Byrrhidae] would seem to be redundant, i.e. a duplicate in my system, to be
deleted. If no-one has evidence that this exists as a separate
nomenclatural entity, I shall delete it (actually the record stays on the
system but is hidden, and is redirected to the correct name publication
instance, in case earlier downloaders of my data need to check what has
happened to that record). Thanks for the clarification of the French
translation (my schoolboy French being pretty rusty by now).

In other similar cases, the original publication information e.g. in Neave
is helpful in establishing whether we are dealing with a single or multiple
publication instances, however this name appears to be missing from there.

Best regards - Tony
