[Taxacom] New species descriptions based on only 1 specimen

Difficult to answer by yes or no. In theory, it's not a good idea to
describe a species on 1 specimen. But... In the case of a revision, better
to describe the species available, even if there is only one specimen, so
all species are available to play with. Another person can find the way to
rear the species or to collect more and confirm the validity of the species
or put it as a synonym of another species. I know it's not an election, but
my vote would be to describe the species, even on an orphan specimen.
