    Jeremy is not the image with 21on it that Blair & Watkins 2009 assign to Reinhardtites clavicaviformis Varol 1991. I think the genus may be a problem I got a few images of this species

    Hi Kevin

    Interesting comment - I have not put the Blair & Watkins paper in to te system - although Rich Howe has got it into the Catalog. I'll have to ask Jackie her opinion on the species.

    Jeremy
