meeting announcements, etc., please feel free to send them to me and I can post them to the Facebook page, or just send out a tweet with the @CrayfishOrg tag and it should make it out to all members that have linked their social networking accounts to our sites. As another bit of news, I have also been working on an update and redesign of the IAA website, which will hopefully launch sometime later this year. Our current website was initially created back in 2001 and has been in dire need of both a cosmetic and technology update for quite some time. You will hear more about this upcoming site launch at a later date. If you have any other ideas that you feel may help our association to grow and prosper long into the future, please feel free to contact either myself, or any one of the IAA offic- ers, with your comments or suggestions.

When writing a paper recently I thought it would be useful to say in the introduction how many extant crayfish David Holdich species there are. This proved more difficult than I thought! (Honorary IAA member, ex-IAA President) Nottingham, England (February 2014) My interest was raised by this question when I read [email protected] Gherardi (2010) who stated that there were 644 described species.

Mitochondrial figure of ‘over 644’, if you add the numbers up in their table phylogeography of New Zealand freshwater , one row totals 638 and another 659!). I thought these figures Paranephrops spp. Molecular Ecology 16:1897–1908. were a bit high as Sibley et al. (2011) quoted a figure of 590.
