Subspecies
editWHO (1995)[2] recognized the following subspecies:
- Bithynia siamensis siamensis - synonym: Bithynia siamensis goniomphalus[2]
- Bithynia siamensis funiculata[2]
- Bithynia siamensis laevis[2]
Bithynia siamensis and Bithynia funiculata (synonym: Bithynia goniomphala) were recognized as separate species in the 2012 IUCN Red List.[1][3]
Distribution
editThis species occurs in:
The population of Bithynia siamensis fluctuates during the year.[4]
Parasites
editBithynia siamensis serves as a first intermediate host for Southeast Asian liver fluke Opisthorchis viverrini.[2] The number of excretory cells of the digestive system is increased in infected Bithynia siamensis.[5]
Parasites of Bithynia siamensis include trematode Multicotyle purvisi.[6]
