Filopaludina martensi

Filopaludina martensi is a species of large freshwater snail with a gill and an operculum, an aquatic gastropod mollusc in the family Viviparidae.

[3] The peristome is straight, thick, blunt, often outwardly blackish.

[3] The operculum has the color of horn with golden shining and it is widely ovate.

[3] This species was firstly described by Eduard von Martens under the name Paludina cingulata in 1860 based on specimen collected by Henri Mouhot.

[3] Georg Ritter von Frauenfeld created a new replacement name Vivipara martensi for this species in 1864, because the name Vivipara cingulata was already used for a fossil species by Philippe Matheron before.

[1] This species is found in Cambodia, Indonesia, Laos, Malaysia, Philippines, Thailand and Vietnam.
