  This, 
  the 
  genotypic 
  species, 
  is 
  known 
  from 
  only 
  the 
  unique 
  female 
  

   from 
  Senegambia. 
  The 
  finely 
  punctate, 
  black, 
  maculated 
  abdomen 
  

   readily 
  separates 
  hraueri 
  from 
  the 
  following 
  three 
  species.

  The 
  bright 
  red, 
  immaculate, 
  finely 
  punctate 
  abdomen 
  distinguishes 
  

   fugosofunctata 
  from 
  all 
  other 
  members 
  of 
  the 
  hraueri 
  group 
  except 
  

   bridwelli. 
  The 
  diiferential 
  characters 
  separating 
  the 
  present 
  species 
  

   from 
  hridwelli 
  have 
  been 
  presented 
  in 
  the 
  foregoing 
  key 
  to 
  species.
