  resembles 
  that 
  species, 
  especially 
  in 
  the 
  markings 
  of 
  the 
  abdomen

   wings, 
  but 
  is 
  distinguishable, 
  inter 
  alia, 
  by 
  its 
  smaller 
  size, 
  by 
  the 
  less 
  elongate 
  

   antennae, 
  and 
  by 
  the 
  more 
  swollen 
  first 
  antennal 
  joint.
