Hello,
as I saw the pircture for the first time I was thinking about that this could be one of the 'new' supspecies from T. eques - maybe T. eques carmensis. I haven't found any realistic photographs from this supspecies, but here
http://diglib1.amnh.org/novitates/i0...ensis%20pdf%22 is the link to the description of all new subspecies (it's an pdf-file).
Best regards from Jan.
