  Description. 
  — 
  This 
  description 
  is 
  based 
  on 
  the 
  holotype 
  and 
  para- 
  

   types 
  listed 
  above. 
  The 
  counts 
  are 
  given 
  for 
  the 
  holotype, 
  followed 
  

   in 
  parentheses 
  by 
  the 
  average 
  and 
  range 
  of 
  counts 
  taken 
  from 
  the 
  11 
  

   paratypes. 
  When 
  counts 
  for 
  the 
  paratypes 
  are 
  identical 
  with 
  those 
  

   of 
  the 
  holotype, 
  only 
  one 
  number 
  is 
  given. 
  Certain 
  characters 
  are 
  

   compared 
  with 
  other 
  species 
  of 
  the 
  genus 
  in 
  tables
