   dead

  Remarks. 
  — 
  Females 
  are 
  somewhat 
  variable 
  in 
  the 
  distinctness 
  of 
  the 
  

   head 
  markings 
  and 
  in 
  the 
  color 
  of 
  the 
  haustellum, 
  which 
  may 
  be 
  light 
  

   or 
  dark. 
  Males 
  sometimes 
  have 
  the 
  terminal 
  process 
  (aedeagus) 
  of 
  

   the 
  genitalia 
  retracted. 
  

  

  This 
  species 
  can 
  be 
  distinguished 
  in 
  the 
  female 
  from 
  nigriventris 
  by 
  

   the 
  paler 
  dorsal 
  color, 
  lack 
  of 
  dark 
  pleural 
  areas, 
  and 
  more 
  complete 
  

   abdominal 
  setosity. 
  The 
  male 
  can 
  be 
  told 
  from 
  nigriventris 
  and 
  other 
  

   species 
  by 
  its 
  large 
  aedeagus 
  and 
  the 
  anterior 
  loop 
  of 
  its 
  associated 
  

   genitalic 
  structures. 
  

  

  The 
  fly 
  is 
  named 
  for 
  C. 
  L. 
  Wyman, 
  who 
  worked 
  with

  many 
  

   months 
  overseas
