Parafossarulus spiridonovi is a species of freshwater snail with gills and an operculum, an aquatic prosobranch gastropod mollusk in the family Bithyniidae.

The specific name spiridonovi is apparently in honour of Croatian malacologist Spiridon Brusina.

[citation needed] The type locality of this species is near the village of Kirovo, in the basin of the Bidzan River in Jewish Autonomous Oblast, Khabarovsky District, Russia.

[3] Parafossarulus spiridonovi serves as the first intermediate host for the trematode Notocotylus intestinalis (natural infection).

[6] Parafossarulus spiridonovi serves as the second intermediate host for the trematode Sphaeridiotrema monorchis (experimental infection).
