My paper (Chapman 2009 - ref below) looking in detail at each taxonomic
group gave a figure of 1.9 million already published names and produced
an estimate for the total number of species of ~11 million (8.73 million
eukaryotic species). I think you must have misinterpreted the Costello
et al. paper as the figures you give suggest that we know all the species.
It is interesting to me that the new paper by Mora et al. in PLos
Biology using a completely different approach to mine, have come up with
a very similar estimate.
