[Taxacom] molecular species description

[Stephen Thorpe]

> Not so according to his later paper
Well, if it was an independent judgement by someone else, I might give  
it more weight, but the same guy defending himself from criticism, and  
without the benefit of us hearing the other side of the story???  
Sounds a bit "dodgy" to me! Anyway, without naming names, I heard a  
VERY negative critique of his work on this from someone who is a  
MOLECULAR taxonomist on these critters!
