  forms 
  for 
  the 
  species 
  having 
  two 
  

   longitudinal 
  furrows 
  the 
  sub-genus

  Karennee,

   which 
  is 
  very 
  different 
  from 
  the

   e.g., 
  the 
  median 
  segment 
  is 
  tranversely 
  striated, 
  the 
  head 
  

   is 
  without 
  keels, 
  the

  not 
  punctured,
