  tangent

   eye 
  nearly 
  twice 
  as 
  long 
  as 
  broad, 
  rather 
  shallowly 
  emarginate; 
  

   ocelli 
  narrowly 
  but 
  distinctly 
  separated 
  from 
  eyes; 
  malar 
  space 
  

   short 
  but 
  distinct; 
  face 
  and 
  clypeus 
  nearly 
  flat, 
  coarsely 
  punctate, 
  

   the 
  face 
  more 
  densely 
  and 
  finely 
  so 
  medially 
  and 
  polished

  nearly 
  

   impunctate 
  laterally, 
  the 
  head 
  elsewhere 
  impunctate 
  and 
  polished; 
  

   clypeus 
  twice 
  as 
  broad 
  as 
  long, 
  very 
  broadly 
  truncate 
  at 
  apex 
  ; 
  exposed 
  

   portion 
  of 
  labrum 
  nearly 
  as 
  long 
  as 
  clypeus, 
  heavily 
  sclerotized, 
  

   punctate,

  long 
  rather 
  dense 
  hair; 
  mandible 
  more 
  than

  as 
  broad 
  basally, 
  tapering 
  to 
  apex, 
  slightly 
  twisted, 
  punctate; 
  

   antenna 
  slightly 
  shorter 
  than 
  body 
  rt:40-jointed, 
  slender, 
  of 
  nearly 
  

   uniform 
  diameter 
  except 
  for 
  a 
  slight 
  apical 
  taper. 
  

  

  Thorax: 
  Stout, 
  shining, 
  punctate, 
  mesoscutum 
  less 
  distinctly 
  so, 
  

   notaulices 
  briefly 
  impressed 
  anteriorly; 
  scutellum 
  high, 
  polished 
  and 
  

   sparsely 
  punctate, 
  margined 
  basally, 
  its 
  frenum 
  more 
  coarsely 
  and 
  

   densely 
  punctate; 
  frenum 
  of 
  postscutellum 
  striate; 
  propodeum 
  with 
  

   basal 
  carina 
  medially 
  and 
  the 
  apical 
  carina 
  laterally 
  distinct, 
  the 
  

   latter 
  sometimes 
  complete, 
  basal 
  area 
  polished 
  and 
  sparsely 
  punctate, 
  

   the 
  rest 
  of 
  the 
  surface 
  finely 
  rugoso-punctate

  large, 
  elongate 
  

   reniform. 
  Wings 
  rather 
  densely

   stigma 
  and 
  in 
  base 
  of 
  radiellan 
  cell; 
  stigma 
  narrowly 
  triangular 
  with 
  

   radius 
  distinctly 
  basad 
  of 
  middle; 
  thickening 
  of 
  basal 
  abscissa 
  of 
  

   radius 
  extending 
  nearly 
  to 
  middle; 
  apical 
  abscissa 
  slightly 
  curved; 
  

   basal
