|Scientific Name:||Filopaludina sumatrensis|
|Species Authority:||(Dunker, 1852)|
Brandt (1974) described various subspecies of Filopaludina sumatrensis (Dunker, 1852); F. sumatrensis speciosa, F. sumatrensis polygramma, and F. sumatrensis peninsularis. According to Brandt this species was first described from Sumatra and later also from Java, Malaysia, Indochina and Thailand under synonyms. Though the continental taxa seem to be closely related to the Indonesian type form, Brandt (1974) found it more convenient to treat the continental taxa under different names. Here we assess the nominate species until further taxonomic study resolves uncertainty. He also mentions intermediate morphs between F. sumatrensis polygramma and F. sumatrensis speciosa and between the type form and continental taxa.
Molecular as well as morphological studies will help to clarify the phylogenetic status of concerning taxa.

The species has a wide range and is considered Least Concern. The identity and distributions of specimens from throughout the species' range requires further study.
The subspecies F. s. speciosa is known from much of eastern and southern Thailand (provinces of Khon Kaen, Kalasin, Mahasarakam, Roi Ett, Nakon Panom, Ubon, Buriram, Surin, Sri Saket, Chantaburi, Prachinburi, Nakhon Si Thammarat, Phattalung, Songkhla, Yala, Pattani, and Narathiwat), Lao PDR, Cambodia and northern Viet Nam. F. s. polygramma is known from central and southern Thailand and Yangon and southern Myanmar. F. s. peninsularis is known from a few localities in southern Thailand (Brandt 1974, Sri-aroon et al. 2007), Malaysia and Singapore (Tan and Woo 2010).
Most records from Malaysia refer to other species (Brandt 1974), however the species is present in Peninsular Malaysia and Indonesia (Sumatra; type locality). Further work is required to confirm the identity of specimens from throughout its range.

|Population:||No information available.|
|Habitat and Ecology:||
The subspecies F. s. speciosa is predominantly fluviatile, but it is also found in still water.
Several cercariae of unidentified trematodes have been obtained in this species and it serves as an important intermediate host for representatives of the trematode family, as it is generally infected with metacercariae of Echinostomatidae. It can cause also Angiostrongyliasis.
|Major Threat(s):||Although likely to be threatened in parts of its range, the threats are not thought to be widespread.|
|Conservation Actions:||Surveys are required to confirm the distribution and taxonomic status of specimens from through its range.|
