Geographic Range [top]
Range Description:
Lamellidens lamellatus is known from the lower Gangetic plain in West Bengal, and a lake in the Damodar River basin (Tenughat reservoir) in Jharkhand in India. It is also reported from Sri Lanka and Myanmar (Mandalay, Pegu and Bhamo) (Preston 1915, Subba Rao 1989, Nesemann et al. 2005, 2007). It is likely to be present in further Indian states and expert survey is required to confirm this; several of the known records are nearly a century old (Preston 1915).
