Here's a comparison of the three species traditionally assigned to Tapejara but now split up into two or three different genera. Note that Naish and Witton 2006 found T. navigans basal to all other tapejarines (or tapejarids, if you prefer a topology where the thalassodromines are closer to azhdarchids) and therefore still deserves its own genus name. Some variation on Ingridia would be nice...
The extent of the beaks and pycnofibres based on the new specimen described in:
Pinheiro, F.L., Fortier, D.C., Schultz, C.L., De Andrade, J.A.F.G. and Bantim, R.A.M. (in press). "New information on Tupandactylus imperator, with comments on the relationships of Tapejaridae (Pterosauria)." Acta Palaeontologica Polonica, in press, available online 03 Jan 2011.
Also, a yet-undescribed specimen may preserve a Pterorhynchus style "beard", which I restored on T. imperator. The specimen described by Pinheiro et al. does have pycnofibres up to the mandibular keel, so it's not so far out for the beard to be real and not, say, a bit of plant material.
