Tylomelania is a genus of freshwater snails which have an operculum, aquatic gastropod mollusks in the family Pachychilidae.
Distribution
These freshwater snails are endemic to Sulawesi in Indonesia,[2] with the vast majority restricted to Lake Poso and the Malili Lake system (consisting of Matano and Towuti, and the smaller Lontoa (Wawantoa), Mahalona, Masapi).[5]
Species
There were known 34 described species in 2005.[2] Thomas von Rintelen with colleagues described 15 new species of Tylomelania in 2003-2008.

Description
In species within this genus, the albumen gland is very large.[2]

Ecology
Species in the genus Tylomelania are ovoviviparous.[2] Newly hatched snails of some species of Tylomelania measure nearly 2 cm and are the largest newly hatched viviparous gastropods.[2]
