"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
family. p 132- lists in this family "all other acoels that lack feamle ducts" includes:
Proporus, Haplodiscus, Remicola, Achoerus, Afronta, Childia, Avagina.
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,
Afronta and Childia- also remove Achoerus to the Tribe Proandropera-Abursalia.
