  Two 
  species 
  of 
  this 
  genus 
  have 
  been 
  described 
  previously, 
  P. 
  prumosa 
  

   Kertesz

  the 
  genotype, 
  from 
  Formosa, 
  and 
  P. 
  glabra 
  Bezzi 
  1927, 
  

   from 
  Fiji. 
  The 
  following 
  key, 
  based 
  on 
  the 
  descriptions, 
  will 
  separate 
  

   these

  the 
  one
