Solenaia is a genus of freshwater mussels in the family Unionidae. [1] [2] [3] [4] They have a very elongated shell [3] [4] that lacks dentition. [3]
There is only one recognized extant species: [1] [2]
There is also one species only known from the fossil record: [1]
Many other species have been recognized before. [1] [3] [4] Chinese literature sources have records of at least five different species. [5] However, recent taxonomic work has moved most former Solenaia species to other genera, including Sinosolenaia , Parvasolenaia , and Koreosolenaia . [4]
The only extant species, Solenaia emarginata (synonym: Solenaia khwaenoiensis [1] [2] ) is found in Thailand [2] [6] [7] in Chao Phraya and Mae Klong drainages. [3]
