Species within the genus ''Paraprosostenia'' include:
* ''
Paraprosostenia minuta'' Annandale, 1919 - type species, fossil of
Pleistocene of
Namma in northern
Burma,

The length of the shell is 6 mm.
It was found in freshwater lake beds,
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''.

Subsequently Davis et al. (1981)
restricted the genus ''Paraprosostenia'' to the Pleistocene of Burma.
These four extant species were moved to the newly established genus ''
