  by 
  the 
  interrupted, 
  transverse, 
  abdominal 
  bands 
  being 
  

   very 
  dark, 
  more 
  regular 
  in 
  shape, 
  approaching 
  closer 
  to 
  the 
  hind 
  margin 
  of 
  the 
  segment 
  

   in 
  each 
  case, 
  and 
  having 
  their 
  inner 
  ends 
  close 
  together, 
  sharply 
  defined 
  and 
  terminating 
  

   squarely 
  {instead 
  of 
  more 
  or 
  less 
  taper 
  ed-off 
  or 
  even 
  obsolescent)

  pale 
  median 
  

   interspace

  the 
  third

  the 
  fifth 
  tergites

  a 
  narrow, 
  clean-cut, 
  longitudinal

  is 
  of 
  uniform 
  width 
  on 
  the 
  third

  slightly 
  narrower 
  

   on 
  the 
  fifth

  a 
  and 
  b, 
  fig. 
  1) 
  ; 
  distinguishable 
  also 
  in 
  the 
  male 
  sex 
  by 
  the 
  different 
  

   shape, 
  heavier 
  chitinisation 
  and 
  much 
  darker 
  coloration 
  of 
  the 
  superior 
  claspers, 
  by 
  the 
  

   greater 
  size

  much 
  greater 
  prominence 
  of 
  the

  tooth

  on 
  the 
  distal 
  

   margin 
  of 
  each

  the 
  latter, 
  and 
  by 
  the 
  strikingly 
  different 
  shape

  median 
  lobes
