Now I've had sight of Disney's key (thanks guys ;)), I'm sure this is
T. verralli. I've tried again without success to demonstrate this in a photo. This dorsal view at least shows that the central projection at the top of the head has side-lobes. With the microscope I can see that the three lobes are pointed enough to match the diagram for
verralli.
