Parabasalid Rostronympha. Image by Guy Brugerolle via Micro*scope.
I can't find the original description at the moment, but vaguely recall having searched for it ambitiously once and failed miserably. It's supposed to be (Duboscq, Grassé & Rose, 1937), with a later mention in PP Grasse, A Hollande (1963) Ann. Sci. Natur. Zool. Ser "Les flagelles des genres Holomastigotoides et. Rostronympha". Might as well order it sometime...
And now onto a really nice taxonomic summary of parabsalians by Cepicka, Hampl and Kulda 2009 in Protist:
Recently revised parabasalian taxonomy.
Ok, I must run...will definitely get back to parabasalians in much more detail later. Some people in our department happen to be rather obsessed with them, and obsession can be contagious. But for now, feel free to join me in salivating over that really sweet diagram!
