Some new papers on DNA based species delimitation have been published.
A paper about a mutilocus species delimitation method has just been published.
Fujisawa, T., Aswad, A. and Barraclough, T.G. (2016) A rapid and scalable method for multilocus species delimitation using Bayesian model comparison and rooted triplets. Syst.Biol. doi: 10.1093/sysbio/syw028
It describes a new multilocus species delimitation method which is applicable to large data.
Another paper I coauthored is about the GMYC and taxon sampling.
It is about empirical and simulation studies about the effects of different taxon sampling schemes on the single locus delimitation method.
