  penis 
  (?). 
  

  

  on 
  the 
  dorsal 
  surface; 
  otherwise 
  it 
  does 
  not 
  differ 
  from 
  the 
  female; 
  

   the 
  chitinous 
  genital 
  structures 
  are 
  rather 
  ill-defined, 
  the 
  large 
  penis 
  

   (?) 
  (fig. 
  7,5), 
  projecting 
  slightly 
  from 
  the 
  genital 
  aperture 
  at 
  the 
  

   posterior 
  extremity 
  of 
  the 
  body.

  at 
  

   the

  parts 
  closely 
  resembling 
  those 
  of

  much 
  shorter, 
  reaching 
  to
