Graff L v 1882 (citation)- give definition:
  	"Acoela with one genital opening, without female accessory apparatus (bursa seminalis),
  	with weak penis.  The single genus Proporus lacks a pharynx, the mouth opening lies behind
  	the otolith and there are two well defined eyes.  The body is small and oval, broadly 
  	round at both ends (1-1.5 mm long)". [BUSH L translation]
  Graff L v 1904 (citation)- definition "Acoela with one genital pore, without or with a bursa
  	seminalis, with ovary."

  Graff L v 1905 (citation), p 4.
	"Acoela with a single genital opening, with or without a bursa seminalis, with ovaries. 
	Testes sometimes follicular, sometimes compact (Otocelis rubropunctata, Haplodiscus).
	Location of the mouth and length of the sometimes almost completely lacking pharynx varies.
	Elongated, enrolled or platelike in form, from 018-2.5 mm.  Littoral or pelagic, one species
	(Haplodiscus incola) parasitic."  Tierreich - Graff L v 1905 (citation), p 4.  3 genera
  Hyman LH 1951 (citation)- p 128- notes there are no female organs (ducts, bursae, etc.) in this

  Westblad E 1948 (citation)- p 52, 55, 56 in the key take out of this family Diopisthoporidae for 
	new family and for Haploposthiidae, the genera Haploposthia, Paranaperus, Paraproporus,
