†Paraprosostenia is a fossil genus of prehistoric^[1] freshwater snails, aquatic gastropod mollusks in the family Pomatiopsidae.

Species

Species within the genus Paraprosostenia include:

Paraprosostenia minuta Annandale, 1919 - type species, fossil of Pleistocene of Namma in northern Burma,^[1] The length of the shell is 6 mm.^[2] It was found in freshwater lake beds,^[2]^[3] so it is presumed to be a freshwater species as is the case in all other Triculinae.

Davis (1979) classified also four extant species within the genus Paraprosostenia.^[2] Later Davis (1981)^[4] referred number of species in Paraprososthenia to be ten.^[4] Subsequently Davis et al. (1981)^[1] restricted the genus Paraprosostenia to the Pleistocene of Burma.^[1] These four extant species were moved to the newly established genus Neoprososthenia:^[1]

(extant) Paraprososthenia hanseni Brandt, 1970^[2] is a synonym of Neoprososthenia hanseni (Brandt, 1970)^[4]
(extant) Paraprososthenia iijimai Brandt, 1970^[2] is a synonym of Neoprososthenia iijimai (Brandt, 1970)^[4]
(extant) Paraprososthenia levayi (Bavay, 1895)^[2] is a synonym of Neoprososthenia levayi (Bavay, 1895)^[4]
(extant) Paraprososthenia poirieri (Brandt, 1970)^[2] is a synonym of Neoprososthenia poirieri (Brandt, 1970)^[4]
