Notes for Proporidae Schizoprora
Schizopora = Schizoporus = Proporus Schmidt O 1852 (citation)- Carus JV 1863 (citation)- p 473 defines. Graff L v 1882 (citation)- gives as synonym or Proporus venenosa. Pereyaslawzewa D 1892 (citation)- places Proporus venenosus Graff in this genus- see Porporus (places the genus Schizopora in a Tribe Pseudoacoels) Dorjes J 1971 (citation)- Schizopora venenosoa is synonym with Proporus venenosa.
Notes for Proporidae Archiproporus
Only species moved to Proporus see Westblad E 1945 (citation)- p 43. Archiproporus minimus = Proporus minimus An der Lan H 1936 (citation)- p 322-3 describes and illustrates, figure 4 and 16. Westblad E 1945 (citation)- p 43 says Archiproporus minimus = Proporus minimus. Westblad E 1948 (citation)- p 58 says he has eliminated this genus. Dorjes J 1971 (citation)- also places minimus in Proporus. Karling TG 1974 (citation)- says Dorjes considers this a valid genus. Dorjes J, Karling TG 1975 (citation)- lists.
