  This 
  new 
  species 
  has 
  the 
  upper 
  parts 
  like 
  Acredula 
  rosea, 
  

  

  but 
  the 
  black 
  on 
  the 
  sides 
  of 
  the 
  head 
  is 
  much 
  broader 
  and 
  

  

  extends 
  to 
  the 
  base 
  of 
  the 
  bill, 
  the 
  lores 
  also 
  being

  underparts 
  resemble

  patch 
  on
