  vomerifera 
  group 
  

  

  The 
  propria 
  group 
  includes 
  only 
  this 
  species; 
  the 
  second 
  group 
  

   includes 
  ecuadoriensis 
  Muir 
  and 
  quadrimaculata 
  (described 
  below) 
  ; 
  

   albolineata 
  Muir, 
  by 
  contrast, 
  typifies 
  a 
  large 
  group 
  including 
  hnm- 
  

   nivenosa 
  Muir, 
  latinotata 
  Muir, 
  longispinis 
  Muir, 
  quadrispinosa 
  Muir,

   fuscipennis 
  Muir, 
  alhomarginata 
  Muir, 
  ohscurata 
  Muir, 
  and 
  two 
  

   species, 
  raamiorata 
  and 
  ohliquivitta^ 
  described 
  below; 
  the 
  ohtorta 
  

   group, 
  including 
  obtorta 
  Muir, 
  pulchella 
  Muir, 
  and 
  fuscomarginata 
  

   Muir, 
  would 
  appear 
  to 
  be 
  quite 
  closely 
  related 
  to 
  the 
  infuscata 
  group 
  

   {infuscata 
  Muir, 
  angustinofata 
  Muir, 
  and 
  falcata 
  (described 
  below) 
  ) 
  

   if 
  judged 
  by 
  the 
  shape 
  of 
  the 
  anal 
  segment; 
  omata 
  Muir 
  is 
  grouped 
  

   with 
  altamasonica 
  Muir 
  and 
  discrepans 
  Muir, 
  huigrensis 
  Muir 
  is 
  

   somewhat 
  doubtfully 
  associated 
  with 
  furcata 
  Muir, 
  while 
  bicaudata 
  

   Muir, 
  maculipennis 
  Muir, 
  and 
  curvivitta 
  and 
  daedala 
  (both 
  described 
  

   below) 
  form 
  a 
  fairly 
  closely 
  knit 
  group 
  ; 
  vomerifera 
  (described 
  below) 
  

   is 
  placed 
  apart, 
  though 
  it 
  shares 
  characters 
  with 
  the 
  preceding 
  group 
  

   and 
  with 
  the 
  obtorta 
  group, 
  on 
  the 
  ground 
  that 
  the 
  shape 
  of 
  the 
  genital 
  

   styles 
  and 
  the 
  general 
  structure 
  of 
  the 
  aedeagus 
  differ 
  considerably 
  

   from 
  those 
  of 
  all 
  the 
  species 
  so 
  far 
  considered.
