  Remarks. 
  — 
  S. 
  fiehrigi 
  Kieffer, 
  1917, 
  from 
  Paraguay 
  and 
  Brazil, 
  

   resembles 
  S. 
  coquilletti 
  very 
  closely 
  except 
  for 
  the 
  abdominal 
  markings, 
  

   with 
  a 
  pair 
  of 
  large 
  lateral 
  brown 
  spots 
  on 
  the 
  first 
  tergite 
  and 
  a 
  large 
  

   median 
  brown 
  spot 
  on 
  the 
  second, 
  and 
  tergites 
  3 
  to 
  7 
  with 
  dark 
  markings 
  

   on 
  the 
  disc 
  rather 
  than 
  on 
  the 
  margins. 
  In 
  the 
  male 
  genitalia 
  of 
  

   jiehrigi 
  the 
  basistyles 
  bear 
  a 
  prominent 
  mesal 
  lobe, 
  the 
  dististyles 
  are 
  

   slenderer 
  at 
  the 
  apices, 
  the 
  lateral 
  bars 
  of 
  the 
  aedeagus 
  are 
  slender 
  

   without 
  capitate 
  tips, 
  and 
  the 
  parameres 
  are 
  not 
  so 
  broad 
  and 
  the 
  

   lateral 
  tooth 
  is 
  not 
  so 
  prominent.
