M. pallida, Green. The pygidial characters of the two species are also very similar. 
But, while in pallida the lateral lobules are more than half the size of the median 
lobes, in ocellata the lateral lobules are markedly smaller and narrower. The main 
structural difference, however, is in the presence of the well-defined eye-spots on the 
cephalic segment.
