Kiaora Larry - Peter here replying from Salzburg. Korthalsella is now back in the Viscaceae (or rather its been there a while). I wrote a summary of all the changes in the Santales in Trilepidea 91 called "What's up in the Santales?'" Seems everyone has overlooked this. Anyway that article was based on a paper by Dan Nickrent and friends published in Taxon which I had overlooked when compiling what is now de Lange & Rolfe (2010). The paper you want is:
Nickrent, D.L.; Malécot, V.; Vidal-Russell, R.; Der, J.P. 2010: A revised classification of Santalales. Taxon 59: 538-558.
But note they got Mida wrong in there. Mida IS MONOTYPIC and it is ENDEMIC to New Zealand. Also Mida is in the Nanodeaceae - we only have one Santalaceae representtaive now - Exocarpos
