  SIMILAR LOOKING SPECIES  
As young males, the first 3 are grouped together with julia due to the similar pattern on the abdomen. Of these 4, only brachiale and guineense have dark claspers with julia and stemmale having white claspers. The Pt of julia in most cases turns black very fast. Thorax markings very similar to robustum but the shape and color of the Pt together with the large number of doubled cells in the Rspl loops of robustum should be enough to differenciate these two.

  SIMILAR LOOKING SPECIES  
Abdomen and thorax patterns may look similar, but when young only julia has pale claspers.  On the mature female, the Ax veins are ALWAYS dark and the pterostigma is orange to dark brown/black in contrast with brachiale that ALWAYS have pale Ax veins with light coloured Pt's.
