FIGURE 10. Photograph of the anterior arculus of Lutetialestes uniformis (holotype USNM 559048). Note RP separating from RA & RP distal of the arculus. The apparent double nature of vein CuP and the posterior side of dc is an artefact of preservation that resulted from a splitting of the two wing membranes of the single preserved wing. Scale bar = 0.5 mm.
